+
+  * pxar: accompany existing .zip download support with a tar.zst(d) one. The

+
+Certificate Management
+----------------------
+
+Access to the API and thus the web-based administration interface is always
+encrypted through ``https``. Each `Proxmox Backup`_ host creates by default its
+own (self-signed) certificate. This certificate is used for encrypted
+communication with the host’s ``proxmox-backup-proxy`` service, for any API
+call between a user or backup-client and the web-interface.
+
+Certificate verification when sending backups to a `Proxmox Backup`_ server
+is either done based on pinning the certificate fingerprints in the storage/remote
+configuration, or by using certificates, signed by a trusted certificate authority.
+
+.. _sysadmin_certs_api_gui:
+
+Certificates for the API and SMTP
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`Proxmox Backup`_ stores it certificate and key in:
+
+-  ``/etc/proxmox-backup/proxy.pem``
+
+-  ``/etc/proxmox-backup/proxy.key``
+
+You have the following options for the certificate:
+
+1. Keep using the default self-signed certificate in
+   ``/etc/proxmox-backup/proxy.pem``.
+
+2. Use an externally provided certificate (for example, signed by a
+   commercial Certificate Authority (CA)).
+
+3. Use an ACME provider like Let’s Encrypt to get a trusted certificate
+   with automatic renewal; this is also integrated in the `Proxmox Backup`_
+   API and web interface.
+
+Certificates are managed through the `Proxmox Backup`_
+web-interface/API or using the the ``proxmox-backup-manager`` CLI tool.
+
+.. _sysadmin_certs_upload_custom:

+
+Trusted certificates via Let’s Encrypt (ACME)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`Proxmox Backup`_ includes an implementation of the **A**\ utomatic
+**C**\ ertificate **M**\ anagement **E**\ nvironment (**ACME**)
+protocol, allowing `Proxmox Backup`_ admins to use an ACME provider
+like Let’s Encrypt for easy setup of TLS certificates, which are
+accepted and trusted by modern operating systems and web browsers out of
+the box.
+
+Currently, the two ACME endpoints implemented are the `Let’s Encrypt
+(LE) <https://letsencrypt.org>`_ production and staging environments.
+Our ACME client supports validation of ``http-01`` challenges using a
+built-in web server and validation of ``dns-01`` challenges using a DNS
+plugin supporting all the DNS API endpoints
+`acme.sh <https://acme.sh>`_ does.
+
+.. _sysadmin_certs_acme_account:
+
+ACME Account
+^^^^^^^^^^^^
+
+.. image:: images/screenshots/pbs-gui-acme-create-account.png
+  :align: right
+  :alt: Create ACME Account
+
+You need to register an ACME account per cluster, with the endpoint you
+want to use. The email address used for that account will serve as the
+contact point for renewal-due or similar notifications from the ACME
+endpoint.
+
+You can register or deactivate ACME accounts over the web interface
+``Certificates -> ACME Accounts`` or using the ``proxmox-backup-manager`` command
+line tool.
+
+::
+
+    proxmox-backup-manager acme account register <account-name> <mail@example.com>
+
+.. tip::
+
+   Because of
+   `rate-limits <https://letsencrypt.org/docs/rate-limits/>`_ you
+   should use LE ``staging`` for experiments or if you use ACME for the
+   very first time until all is working there, and only then switch over
+   to the production directory.
+
+.. _sysadmin_certs_acme_plugins:
+
+ACME Plugins
+^^^^^^^^^^^^
+
+The ACME plugin’s role is to provide automatic verification that you,
+and thus the `Proxmox Backup`_ server under your operation, are the
+real owner of a domain. This is the basic building block of automatic
+certificate management.
+
+The ACME protocol specifies different types of challenges, for example
+the ``http-01``, where a web server provides a file with a specific
+token to prove that it controls a domain. Sometimes this isn’t possible,
+either because of technical limitations or if the address of a record is
+not reachable from the public internet. The ``dns-01`` challenge can be
+used in such cases. This challenge is fulfilled by creating a certain
+DNS record in the domain’s zone.
+
+.. image:: images/screenshots/pbs-gui-acme-create-challenge-plugin.png
+  :align: right
+  :alt: Create ACME Account
+
+`Proxmox Backup`_ supports both of those challenge types out of the
+box, you can configure plugins either over the web interface under
+``Certificates -> ACME Challenges``, or using the
+``proxmox-backup-manager acme plugin add`` command.
+
+ACME Plugin configurations are stored in ``/etc/proxmox-backup/acme/plugins.cfg``.
+
+.. _domains:
+
+Domains
+^^^^^^^
+
+You can add new or manage existing domain entries under
+``Certificates``, or using the ``proxmox-backup-manager`` command.
+
+.. image:: images/screenshots/pbs-gui-acme-add-domain.png
+  :align: right
+  :alt: Add a Domain for ACME verification
+
+After configuring the desired domain(s) for a node and ensuring that the
+desired ACME account is selected, you can order your new certificate
+over the web-interface. On success, the interface will reload after
+roughly 10 seconds.
+
+Renewal will happen `automatically <#sysadmin-certs-acme-automatic-renewal>`_
+
+.. _sysadmin_certs_acme_http_challenge:
+
+ACME HTTP Challenge Plugin
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There is always an implicitly configured ``standalone`` plugin for
+validating ``http-01`` challenges via the built-in web server spawned on
+port 80.
+
+.. note::
+
+   The name ``standalone`` means that it can provide the validation on
+   its own, without any third party service.
+
+There are a few prerequisites to use this for certificate management
+with Let’s Encrypts ACME.
+
+-  You have to accept the ToS of Let’s Encrypt to register an account.
+
+-  **Port 80** of the node needs to be reachable from the internet.
+
+-  There **must** be no other listener on port 80.
+
+-  The requested (sub)domain needs to resolve to a public IP of the
+   `Proxmox Backup`_ host.
+
+.. _sysadmin_certs_acme_dns_challenge:
+
+ACME DNS API Challenge Plugin
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On systems where external access for validation via the ``http-01``
+method is not possible or desired, it is possible to use the ``dns-01``
+validation method. This validation method requires a DNS server that
+allows provisioning of ``TXT`` records via an API.
+
+.. _sysadmin_certs_acme_dns_api_config:
+
+Configuring ACME DNS APIs for validation
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+`Proxmox Backup`_ re-uses the DNS plugins developed for the
+``acme.sh``  [1]_ project. Please refer to its documentation for details
+on configuration of specific APIs.
+
+The easiest way to configure a new plugin with the DNS API is using the
+web interface (``Certificates -> ACME Accounts/Challenges``).
+
+Here you can add a new challenge plugin by selecting your API provider
+and entering the credential data to access your account over their API.
+
+.. tip::
+
+   See the acme.sh `How to use DNS
+   API <https://github.com/acmesh-official/acme.sh/wiki/dnsapi#how-to-use-dns-api>`_
+   wiki for more detailed information about getting API credentials for
+   your provider. Configuration values do not need to be quoted with
+   single or double quotes; for some plugins that is even an error.
+
+As there are many DNS providers and API endpoints, `Proxmox Backup`_
+automatically generates the form for the credentials, but not all
+providers are annotated yet. For those you will see a bigger text area,
+into which you simply need to copy all the credential’s
+``KEY``\ =\ ``VALUE`` pairs.
+
+.. _dns_validation_through_cname_alias:
+
+DNS Validation through CNAME Alias
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A special ``alias`` mode can be used to handle validation on a different
+domain/DNS server, in case your primary/real DNS does not support
+provisioning via an API. Manually set up a permanent ``CNAME`` record
+for ``_acme-challenge.domain1.example`` pointing to
+``_acme-challenge.domain2.example``, and set the ``alias`` property in
+the `Proxmox Backup`_ node configuration file ``/etc/proxmox-backup/node.cfg``
+to ``domain2.example`` to allow the DNS server of ``domain2.example`` to
+validate all challenges for ``domain1.example``.
+
+.. _sysadmin_certs_acme_dns_wildcard:
+
+Wildcard Certificates
+^^^^^^^^^^^^^^^^^^^^^
+
+Wildcard DNS names start with a ``*.`` prefix and are considered valid
+for all (one-level) subdomain names of the verified domain. So a
+certificate for ``*.domain.example`` is valid for ``foo.domain.example``
+and ``bar.domain.example``, but not for ``baz.foo.domain.example``.
+
+Currently, you can only create wildcard certificates with the `DNS
+challenge
+type <https://letsencrypt.org/docs/challenge-types/#dns-01-challenge>`_.
+
+.. _combination_of_plugins:
+
+Combination of Plugins
+^^^^^^^^^^^^^^^^^^^^^^
+
+Combining ``http-01`` and ``dns-01`` validation is possible in case your
+node is reachable via multiple domains with different requirements / DNS
+provisioning capabilities. Mixing DNS APIs from multiple providers or
+instances is also possible by specifying different plugin instances per
+domain.
+
+.. tip::
+
+   Accessing the same service over multiple domains increases complexity
+   and should be avoided if possible.
+
+.. _sysadmin_certs_acme_automatic_renewal:
+
+Automatic renewal of ACME certificates
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a node has been successfully configured with an ACME-provided
+certificate (either via ``proxmox-backup-manager`` or via the web-interface/API), the
+certificate will be renewed automatically by the ``proxmox-backup-daily-update.service``.
+Currently, renewal is triggered if the certificate either has already
+expired or if it will expire in the next 30 days.
+
+.. _manually_change_certificate_over_command_line:
+
+Manually Change Certificate over Command-Line
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to get rid of certificate verification warnings, you have to
+generate a valid certificate for your server.
+
+Log in to your `Proxmox Backup`_ via ssh or use the console:
+
+::
+
+   openssl req -newkey rsa:2048 -nodes -keyout key.pem -out req.pem
+
+Follow the instructions on the screen, for example:
+
+::
+
+   Country Name (2 letter code) [AU]: AT
+   State or Province Name (full name) [Some-State]:Vienna
+   Locality Name (eg, city) []:Vienna
+   Organization Name (eg, company) [Internet Widgits Pty Ltd]: Proxmox GmbH
+   Organizational Unit Name (eg, section) []:Proxmox Backup
+   Common Name (eg, YOUR name) []: yourproxmox.yourdomain.com
+   Email Address []:support@yourdomain.com
+
+   Please enter the following 'extra' attributes to be sent with your certificate request
+   A challenge password []: not necessary
+   An optional company name []: not necessary
+
+After you have finished the certificate request, you have to send the
+file ``req.pem`` to your Certification Authority (CA). The CA will issue
+the certificate (BASE64 encoded), based on your request – save this file
+as ``cert.pem`` to your `Proxmox Backup`_.
+
+To activate the new certificate, do the following on your `Proxmox Backup`_
+
+::
+
+   cp key.pem /etc/proxmox-backup/proxy.key
+   cp cert.pem /etc/proxmox-backup/proxy.pem
+
+Then restart the API servers:
+
+::
+
+   systemctl restart proxmox-backup-proxy
+
+Test your new certificate, using your browser.
+
+.. note::
+
+   To transfer files to and from your `Proxmox Backup`_, you can use
+   secure copy: If your desktop runs Linux, you can use the ``scp``
+   command line tool. If your desktop PC runs windows, please use an scp
+   client like WinSCP (see https://winscp.net/).

+The same filter is applied to local groups for handling of the
+``remove-vanished`` option.
+
+.. note:: The ``protected`` flag of remote backup snapshots will not be synced.
+
+Namespace Support
+^^^^^^^^^^^^^^^^^
+
+Sync jobs can be configured to not only sync datastores, but also sub-sets of
+datastores in the form of namespaces or namespace sub-trees. The following
+parameters influence how namespaces are treated as part of a sync job
+execution:
+
+- ``remote-ns``: the remote namespace anchor (default: the root namespace)
+
+- ``ns``: the local namespace anchor (default: the root namespace)
+
+- ``max-depth``: whether to recursively iterate over sub-namespaces of the remote
+  namespace anchor (default: `None`)
+
+If ``max-depth`` is set to `0`, groups are synced from ``remote-ns`` into
+``ns``, without any recursion. If it is set to `None` (left empty), recursion
+depth will depend on the value of ``remote-ns`` and the remote side's
+availability of namespace support:
+
+- ``remote-ns`` set to something other than the root namespace: remote *must*
+  support namespaces, full recursion starting at ``remote-ns``.
+
+- ``remote-ns`` set to root namespace and remote *supports* namespaces: full
+  recursion starting at root namespace.
+
+- ``remote-ns`` set to root namespace and remote *does not support* namespaces:
+  backwards-compat mode, only root namespace will be synced into ``ns``, no
+  recursion.
+
+Any other value of ``max-depth`` will limit recursion to at most ``max-depth``
+levels, for example: ``remote-ns`` set to `location_a/department_b` and
+``max-depth`` set to `1` will result in `location_a/department_b` and at most
+one more level of sub-namespaces being synced.
+
+The namespace tree starting at ``remote-ns`` will be mapped into ``ns`` up to a
+depth of ``max-depth``.
+
+For example, with the following namespaces at the remote side:
+
+- `location_a`
+
+  - `location_a/department_x`
+
+    - `location_a/department_x/team_one`
+
+    - `location_a/department_x/team_two`
+
+  - `location_a/department_y`
+
+    - `location_a/department_y/team_one`
+
+    - `location_a/department_y/team_two`
+
+- `location_b`
+
+and ``remote-ns`` being set to `location_a/department_x` and ``ns`` set to
+`location_a_dep_x` resulting in the following namespace tree on the sync
+target:
+
+- `location_a_dep_x` (containing the remote's `location_a/department_x`)
+
+  - `location_a_dep_x/team_one` (containing the remote's `location_a/department_x/team_one`)
+
+  - `location_a_dep_x/team_two` (containing the remote's `location_a/department_x/team_two`)
+
+with the rest of the remote namespaces and groups not being synced (by this
+sync job).
+
+If a remote namespace is included in the sync job scope, but does not exist
+locally, it will be created (provided the sync job owner has sufficient
+privileges).
+
+If the ``remove-vanished`` option is set, namespaces that are included in the
+sync job scope but only exist locally are treated as vanished and removed
+(provided the sync job owner has sufficient privileges).
+
+.. note:: All other limitations on sync scope (such as remote user/API token
+   privileges, group filters) also apply for sync jobs involving one or
+   multiple namespaces.
+
+Bandwidth Limit
+^^^^^^^^^^^^^^^
+
+Syncing a datastore to an archive can produce lots of traffic and impact other
+users of the network. So, to avoid network or storage congestion you can limit
+the bandwidth of the sync job by setting the ``rate-in`` option either in the
+web interface or using the ``proxmox-backup-manager`` command-line tool:
+
+.. code-block:: console
+
+    # proxmox-backup-manager sync-job update ID --rate-in 20MiB

+Markdown Basics

+~~~~~~~~
+
+.. code-block:: md
+
+  # This is a Heading h1
+  ## This is a Heading h2
+  ##### This is a Heading h5
+
+
+Emphasis
+~~~~~~~~
+
+Use ``*text*`` or ``_text_`` for emphasis.
+
+Use ``**text**`` or ``__text__`` for bold, heavy-weight text.
+
+Combinations are also possible, for example:
+
+.. code-block:: md
+
+  _You **can** combine them_
+
+
+Links
+~~~~~
+
+You can use automatic detection of links, for example,
+``https://forum.proxmox.com/`` would transform it into a clickable link.
+
+You can also control the link text, for example:
+
+.. code-block:: md
+
+  Now, [the part in brackets will be the link text](https://forum.proxmox.com/).
+
+Lists
+~~~~~
+
+Unordered Lists
+^^^^^^^^^^^^^^^
+
+Use ``*`` or ``-`` for unordered lists, for example:
+
+.. code-block:: md
+
+  * Item 1
+  * Item 2
+  * Item 2a
+  * Item 2b
+
+
+Adding an indentation can be used to created nested lists.

+
+  1. Item 1
+  1. Item 2
+  1. Item 3
+    1. Item 3a
+    1. Item 3b
+
+NOTE: The integer of ordered lists does not need to be correct, they will be numbered automatically.
+
+Task Lists
+^^^^^^^^^^
+
+Task list use a empty box ``[ ]`` for unfinished tasks and a box with an `X` for finished tasks.
+
+For example:
+
+
+.. code-block:: md
+
+  - [X] First task already done!
+  - [X] Second one too
+  - [ ] This one is still to-do
+  - [ ] So is this one
+
+Tables
+~~~~~~
+
+Tables use the pipe symbol ``|`` to separate columns, and ``-`` to separate the
+table header from the table body, in that separation one can also set the text
+alignment, making one column left-, center-, or right-aligned.
+
+
+.. code-block:: md
+
+  | Left columns  | Right columns |  Some  | More | Cols.| Centering Works Too
+  | ------------- |--------------:|--------|------|------|:------------------:|
+  | left foo      | right foo     | First  | Row  | Here | >center<           |

+  | left rab      | right rab     | And    | Last | Here | The End            |
+
+Note that you do not need to align the columns nicely with white space, but that makes

+
+Code and Snippets
+~~~~~~~~~~~~~~~~~
+
+You can use backticks to avoid processing for a few word or paragraphs. That is useful for
+avoiding that a code or configuration hunk gets mistakenly interpreted as markdown.
+
+Inline code
+^^^^^^^^^^^
+
+Surrounding part of a line with single backticks allows to write code inline,
+for examples:
+
+.. code-block:: md
+
+  This hosts IP address is `10.0.0.1`.
+
+Whole blocks of code
+^^^^^^^^^^^^^^^^^^^^
+
+For code blocks spanning several lines you can use triple-backticks to start
+and end such a block, for example:
+
+.. code-block:: md
+
+  ```
+  # This is the network config I want to remember here
+  auto vmbr2
+  iface vmbr2 inet static

+~~~~~~~~~~~~~~~~~
+
+A datastore can host many backups as long as the underlying storage is big
+enough and provides the performance required for one's use case.
+But, without any hierarchy or separation its easy to run into naming conflicts,

+The backup namespace hierarchy allows you to clearly separate different users
+or backup sources in general, avoiding naming conflicts and providing

+
+Namespace Permissions
+^^^^^^^^^^^^^^^^^^^^^
+
+You can make the permission configuration of a datastore more fine-grained by
+setting permissions only on a specific namespace.
+
+To see a datastore you need permission that has at least one of `AUDIT`,
+`MODIFY`, `READ` or `BACKUP` privilege on any namespace it contains.
+
+To create or delete a namespace you require the modify privilege on the parent
+namespace. So, to initially create namespaces you need to have a permission
+with a access role that includes the `MODIFY` privilege on the datastore itself.
+
+For backup groups the existing privilege rules still apply, you either need a
+powerful permission or be the owner of the backup group, nothing changed here.

+Partitions properly configured and synchronized. It copies certain kernel
+versions to all ESPs and configures the respective bootloader to boot from
+the ``vfat`` formatted ESPs. In the context of ZFS as root filesystem this means
+that you can use all optional features on your root pool instead of the subset
+which is also present in the ZFS implementation in ``grub`` or having to create a
+separate small boot-pool (see: `Booting ZFS on root with grub
+<https://github.com/zfsonlinux/zfs/wiki/Debian-Stretch-Root-on-ZFS>`_).
+
+In setups with redundancy all disks are partitioned with an ESP, by the
+installer. This ensures the system boots even if the first boot device fails
+or if the BIOS can only boot from a particular disk.
+
+The ESPs are not kept mounted during regular operation. This helps to prevent
+filesystem corruption to the ``vfat`` formatted ESPs in case of a system crash,
+and removes the need to manually adapt ``/etc/fstab`` in case the primary boot
+device fails.
+
+``proxmox-boot-tool`` handles the following tasks:
+
+* formatting and setting up a new partition
+* copying and configuring new kernel images and initrd images to all listed ESPs
+* synchronizing the configuration on kernel upgrades and other maintenance tasks
+* managing the list of kernel versions which are synchronized
+* configuring the boot-loader to boot a particular kernel version (pinning)
+
+
+You can view the currently configured ESPs and their state by running:
+
+.. code-block:: console
+
+  # proxmox-boot-tool status
+
+.. _systembooting-proxmox-boot-setup:
+
+Setting up a new partition for use as synced ESP
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To format and initialize a partition as synced ESP, e.g., after replacing a
+failed vdev in an rpool, ``proxmox-boot-tool`` from ``pve-kernel-helper`` can be used.
+
+WARNING: the ``format`` command will format the ``<partition>``, make sure to pass
+in the right device/partition!
+
+For example, to format an empty partition ``/dev/sda2`` as ESP, run the following:
+
+.. code-block:: console
+
+  # proxmox-boot-tool format /dev/sda2
+
+To setup an existing, unmounted ESP located on ``/dev/sda2`` for inclusion in
+`Proxmox Backup`_'s kernel update synchronization mechanism, use the following:
+
+.. code-block:: console
+
+  # proxmox-boot-tool init /dev/sda2
+
+Afterwards `/etc/kernel/proxmox-boot-uuids`` should contain a new line with the
+UUID of the newly added partition. The ``init`` command will also automatically
+trigger a refresh of all configured ESPs.
+
+.. _systembooting-proxmox-boot-refresh:
+
+Updating the configuration on all ESPs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To copy and configure all bootable kernels and keep all ESPs listed in
+``/etc/kernel/proxmox-boot-uuids`` in sync you just need to run:
+
+.. code-block:: console
+
+  # proxmox-boot-tool refresh
+
+(The equivalent to running ``update-grub`` systems with ``ext4`` or ``xfs`` on root).
+
+This is necessary should you make changes to the kernel commandline, or want to
+sync all kernels and initrds.
+
+.. NOTE:: Both ``update-initramfs`` and ``apt`` (when necessary) will automatically
+   trigger a refresh.
+
+Kernel Versions considered by ``proxmox-boot-tool``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following kernel versions are configured by default:
+
+* the currently running kernel
+* the version being newly installed on package updates
+* the two latest already installed kernels
+* the latest version of the second-to-last kernel series (e.g. 5.0, 5.3), if applicable
+* any manually selected kernels
+
+Manually keeping a kernel bootable
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Should you wish to add a certain kernel and initrd image to the list of
+bootable kernels use ``proxmox-boot-tool kernel add``.
+
+For example run the following to add the kernel with ABI version ``5.0.15-1-pve``
+to the list of kernels to keep installed and synced to all ESPs:
+
+.. code-block:: console
+
+  # proxmox-boot-tool kernel add 5.0.15-1-pve
+
+
+``proxmox-boot-tool kernel list`` will list all kernel versions currently selected
+for booting:
+
+.. code-block:: console
+
+  # proxmox-boot-tool kernel list
+  Manually selected kernels:
+  5.0.15-1-pve
+
+  Automatically selected kernels:
+  5.0.12-1-pve
+  4.15.18-18-pve
+
+Run ``proxmox-boot-tool kernel remove`` to remove a kernel from the list of
+manually selected kernels, for example:
+
+.. code-block:: console
+
+  # proxmox-boot-tool kernel remove 5.0.15-1-pve
+
+
+.. NOTE:: It's required to run ``proxmox-boot-tool refresh`` to update all EFI System
+   Partitions (ESPs) after a manual kernel addition or removal from above.

+
+.. _systembooting-determine-bootloader:
+
+Determine which Bootloader is Used
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. image:: images/screenshots/boot-grub.png
+  :target: _images/boot-grub.png
+  :align: left
+  :alt: Grub boot screen
+
+The simplest and most reliable way to determine which bootloader is used, is to
+watch the boot process of the `Proxmox Backup`_ node.
+
+
+You will either see the blue box of ``grub`` or the simple black on white
+``systemd-boot``.
+
+.. image:: images/screenshots/boot-systemdboot.png
+  :target: _images/boot-systemdboot.png
+  :align: right
+  :alt: systemd-boot screen
+
+Determining the bootloader from a running system might not be 100% accurate. The
+safest way is to run the following command:
+
+
+.. code-block:: console
+
+  # efibootmgr -v
+
+
+If it returns a message that EFI variables are not supported, ``grub`` is used in
+BIOS/Legacy mode.
+
+If the output contains a line that looks similar to the following, ``grub`` is
+used in UEFI mode.
+
+.. code-block:: console
+
+  Boot0005* proxmox	[...] File(\EFI\proxmox\grubx64.efi)
+
+
+If the output contains a line similar to the following, ``systemd-boot`` is used.
+
+.. code-block:: console
+
+  Boot0006* Linux Boot Manager	[...] File(\EFI\systemd\systemd-bootx64.efi)
+
+
+By running:
+
+.. code-block:: console
+
+  # proxmox-boot-tool status
+
+
+you can find out if ``proxmox-boot-tool`` is configured, which is a good
+indication of how the system is booted.
+
+
+.. _systembooting-grub:
+
+Grub
+~~~~
+
+``grub`` has been the de-facto standard for booting Linux systems for many years
+and is quite well documented
+(see the `Grub Manual
+<https://www.gnu.org/software/grub/manual/grub/grub.html>`_).
+
+Configuration
+^^^^^^^^^^^^^
+Changes to the ``grub`` configuration are done via the defaults file
+``/etc/default/grub`` or config snippets in ``/etc/default/grub.d``. To regenerate
+the configuration file after a change to the configuration run:
+
+.. code-block:: console
+
+  # update-grub
+
+.. NOTE:: Systems using ``proxmox-boot-tool`` will call
+  ``proxmox-boot-tool refresh`` upon ``update-grub``
+
+.. _systembooting-systemdboot:
+
+Systemd-boot
+~~~~~~~~~~~~
+
+``systemd-boot`` is a lightweight EFI bootloader. It reads the kernel and initrd
+images directly from the EFI Service Partition (ESP) where it is installed.
+The main advantage of directly loading the kernel from the ESP is that it does
+not need to reimplement the drivers for accessing the storage. In `Proxmox
+Backup`_ :ref:`proxmox-boot-tool <systembooting-proxmox-boot-tool>` is used to
+keep the configuration on the ESPs synchronized.
+
+.. _systembooting-systemd-boot-config:
+
+Configuration
+^^^^^^^^^^^^^
+
+``systemd-boot`` is configured via the file ``loader/loader.conf`` in the root
+directory of an EFI System Partition (ESP). See the ``loader.conf(5)`` manpage
+for details.
+
+Each bootloader entry is placed in a file of its own in the directory
+``loader/entries/``
+
+An example entry.conf looks like this (``/`` refers to the root of the ESP):
+
+.. code-block:: console
+
+  title    Proxmox
+  version  5.0.15-1-pve
+  options   root=ZFS=rpool/ROOT/pve-1 boot=zfs
+  linux    /EFI/proxmox/5.0.15-1-pve/vmlinuz-5.0.15-1-pve
+  initrd   /EFI/proxmox/5.0.15-1-pve/initrd.img-5.0.15-1-pve
+
+
+.. _systembooting-edit-kernel-cmdline:
+
+Editing the Kernel Commandline
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can modify the kernel commandline in the following places, depending on the
+bootloader used:
+
+Grub
+^^^^
+
+The kernel commandline needs to be placed in the variable
+``GRUB_CMDLINE_LINUX_DEFAULT`` in the file ``/etc/default/grub``. Running
+``update-grub`` appends its content to all ``linux`` entries in
+``/boot/grub/grub.cfg``.
+
+Systemd-boot
+^^^^^^^^^^^^
+
+The kernel commandline needs to be placed as one line in ``/etc/kernel/cmdline``.
+To apply your changes, run ``proxmox-boot-tool refresh``, which sets it as the
+``option`` line for all config files in ``loader/entries/proxmox-*.conf``.
+
+
+.. _systembooting-kernel-pin:
+
+Override the Kernel-Version for next Boot
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To select a kernel that is not currently the default kernel, you can either:
+
+* use the boot loader menu that is displayed at the beginning of the boot
+  process
+* use the ``proxmox-boot-tool`` to ``pin`` the system to a kernel version either
+  once or permanently (until pin is reset).
+
+This should help you work around incompatibilities between a newer kernel
+version and the hardware.
+
+.. NOTE:: Such a pin should be removed as soon as possible so that all current
+   security patches of the latest kernel are also applied to the system.
+
+For example: To permanently select the version ``5.15.30-1-pve`` for booting you
+would run:
+
+.. code-block:: console
+
+  # proxmox-boot-tool kernel pin 5.15.30-1-pve
+
+
+.. TIP:: The pinning functionality works for all `Proxmox Backup`_ systems, not only those using
+   ``proxmox-boot-tool`` to synchronize the contents of the ESPs, if your system
+   does not use ``proxmox-boot-tool`` for synchronizing you can also skip the
+   ``proxmox-boot-tool refresh`` call in the end.
+
+You can also set a kernel version to be booted on the next system boot only.
+This is for example useful to test if an updated kernel has resolved an issue,
+which caused you to ``pin`` a version in the first place:
+
+.. code-block:: console
+
+  # proxmox-boot-tool kernel pin 5.15.30-1-pve --next-boot
+
+
+To remove any pinned version configuration use the ``unpin`` subcommand:
+
+.. code-block:: console
+
+  # proxmox-boot-tool kernel unpin
+
+While ``unpin`` has a ``--next-boot`` option as well, it is used to clear a pinned
+version set with ``--next-boot``. As that happens already automatically on boot,
+invonking it manually is of little use.
+
+After setting, or clearing pinned versions you also need to synchronize the
+content and configuration on the ESPs by running the ``refresh`` subcommand.
+
+.. TIP:: You will be prompted to automatically do for  ``proxmox-boot-tool`` managed
+   systems if you call the tool interactively.
+
+.. code-block:: console
+
+  # proxmox-boot-tool refresh

+
+This first restores the snapshot to a temporary location, then restores the relevant
+chunk archives, and finally restores the snapshot data to the target datastore.
+
+The ``snapshot`` parameter can be given multiple times, so one can restore
+multiple snapshots with one restore action.
+
+.. NOTE:: When using the single snapshot restore, the tape must be traversed
+   more than once, which, if you restore many snapshots at once, can take longer
+   than restoring the whole datastore.
+
+Namespaces
+^^^^^^^^^^
+
+It is also possible to select and map specific namespaces from a media-set
+during a restore. This is possible with the ``namespaces`` parameter.
+The format of the parameter is
+
+.. code-block:: console
+
+ store=<source-datastore>[,source=<source-ns>][,target=<target-ns>][,max-depth=<depth>]
+
+If ``source`` or ``target`` is not given, the root namespace is assumed.

+Example Setups
+--------------
+
+Here are a few example setups for how to manage media pools and schedules.
+This is not an exhaustive list, and there are many more possible combinations
+of useful settings.
+
+Single Continued Media Set
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The most simple setup: always continue the media-set and never expire.
+
+Allocation policy:
+  continue
+
+Retention policy:
+  keep
+
+This setup has the advantage of being easy to manage and is re-using the benefits
+from deduplication as much as possible. But, it's also prone to a failure of
+any single tape, which would render all backups referring to chunks from that
+tape unusable.
+
+If you want to start a new media-set manually, you can set the currently
+writable media of the set either to 'full', or set the location to an
+offsite vault.
+
+Weekday Scheme
+~~~~~~~~~~~~~~
+
+A slightly more complex scheme, where the goal is to have an independent
+tape or media set for each weekday, for example from Monday to Friday.
+This can be solved by having a separate media pool for each day, so 'Monday',
+'Tuesday', etc.
+
+Allocation policy:
+  should be 'mon' for the 'Monday' pool, 'tue' for the Tuesday pool and so on.
+
+Retention policy:
+  overwrite
+
+There should be a (or more) tape-backup jobs for each pool on the corresponding
+weekday. This scheme is still very manageable with one media set per weekday,
+and could be easily moved off-site.
+
+Multiple Pools with Different Policies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Complex setups are also possible with multiple media pools configured with
+different allocation and retention policies.
+
+An example would be to have two media pools. The first configured with weekly
+allocation and a few weeks of retention:
+
+Allocation policy:
+  mon
+
+Retention policy:
+  3 weeks
+
+The second pool configured yearly allocation that does not expire:
+
+Allocation policy:
+  yearly
+
+Retention policy:
+  keep
+
+In combination with suited prune settings and tape backup schedules, this
+achieves long-term storage of some backups, while keeping the current
+backups on smaller media sets that get expired every three plus the current
+week (~ 4 weeks).

 verify its content against it. Instead only the CRC-32 checksum gets checked.
+
+Troubleshooting
+---------------
+
+Index files(*.fidx*, *.didx*) contain information about how to rebuild a file.
+More precisely, they contain an ordered list of references to the chunks that
+the original file was split into. If there is something wrong with a snapshot,
+it might be useful to find out which chunks are referenced in it, and check
+whether they are present and intact. The ``proxmox-backup-debug`` command line
+tool can be used to inspect such files and recover their contents. For example,
+to get a list of the referenced chunks of a *.fidx* index:
+
+.. code-block:: console
+
+    # proxmox-backup-debug inspect file drive-scsi0.img.fidx
+
+The same command can be used to inspect *.blob* files. Without the ``--decode``
+parameter, just the size and the encryption type, if any, are printed. If
+``--decode`` is set, the blob file is decoded into the specified file ('-' will
+decode it directly to stdout).
+
+The following example would print the decoded contents of
+`qemu-server.conf.blob`. If the file you're trying to inspect is encrypted, a
+path to the key file must be provided using ``--keyfile``.
+
+.. code-block:: console
+
+    # proxmox-backup-debug inspect file qemu-server.conf.blob --decode -
+
+You can also check in which index files a specific chunk file is referenced
+with:
+
+.. code-block:: console
+
+    # proxmox-backup-debug inspect chunk b531d3ffc9bd7c65748a61198c060678326a431db7eded874c327b7986e595e0 --reference-filter /path/in/a/datastore/directory
+
+Here ``--reference-filter`` specifies where index files should be searched. This
+can be an arbitrary path. If, for some reason, the filename of the chunk was
+changed, you can explicitly specify the digest using ``--digest``. By default, the
+chunk filename is used as the digest to look for. If no ``--reference-filter``
+is specified, it will only print the CRC and encryption status of the chunk. You
+can also decode chunks, by setting the ``--decode`` flag. If the chunk is
+encrypted, a ``--keyfile`` must be provided, in order to decode it.
+
+Restore without a Running Proxmox Backup Server
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It's possible to restore specific files from a snapshot, without a running
+Proxmox Backup Server instance, using the ``recover`` subcommand, provided you
+have access to the intact index and chunk files. Note that you also need the
+corresponding key file if the backup was encrypted.
+
+.. code-block:: console
+
+    # proxmox-backup-debug recover index drive-scsi0.img.fidx /path/to/.chunks
+
+In the above example, the `/path/to/.chunks` argument is the path to the
+directory that contains the chunks, and `drive-scsi0.img.fidx` is the index file
+of the file you'd like to restore. Both paths can be absolute or relative. With
+``--skip-crc``, it's possible to disable the CRC checks of the chunks. This
+will speed up the process slightly and allow for trying to restore (partially)
+corrupt chunks. It's recommended to always try without the skip-CRC option
+first.

+  :align: right
+  :alt: Add a traffic control limit
+
+Creating and restoring backups can produce lots of traffic and impact other
+users of the network or shared storages.
+
+Proxmox Backup Server allows to limit network traffic for clients within
+specified networks using a token bucket filter (TBF).
+
+This allows you to avoid network congestion or to prioritize traffic from
+certain hosts.
+
+You can manage the traffic controls either over the web-interface or using the
+``traffic-control`` commandos of the ``proxmox-backup-manager`` command-line
+tool.
+
+.. note:: Sync jobs on the server are not affected by its rate-in limits. If
+   you want to limit the incoming traffic that a pull-based sync job
+   generates, you need to setup a job-specific rate-in limit. See
+   :ref:`syncjobs`.
+
+The following command adds a traffic control rule to limit all IPv4 clients
+(network ``0.0.0.0/0``) to 100 MB/s:
+
+.. code-block:: console
+
+ # proxmox-backup-manager traffic-control create rule0  --network 0.0.0.0/0 \
+   --rate-in 100MB --rate-out 100MB \
+   --comment "Default rate limit (100MB/s) for all clients"
+
+.. note:: To limit both IPv4 and IPv6 network spaces you need to pass two
+   network parameters ``::/0`` and ``0.0.0.0/0``.
+
+It is possible to restrict rules to certain time frames, for example the
+company office hours:
+
+.. tip:: You can use SI (base 10: KB, MB, ...) or IEC (base 2: KiB, MiB, ...)
+   units.
+
+.. code-block:: console
+
+ # proxmox-backup-manager traffic-control update rule0  \
+   --timeframe "mon..fri 8-12" \
+   --timeframe "mon..fri 14:30-18"
+
+If there are more rules, the server uses the rule with the smaller network. For
+example, we can overwrite the setting for our private network (and the server
+itself) with:
+
+.. code-block:: console
+
+ # proxmox-backup-manager traffic-control create rule1 \
+   --network 192.168.2.0/24 \
+   --network 127.0.0.0/8 \
+   --rate-in 20GB --rate-out 20GB \
+   --comment "Use 20GB/s for the local network"
+
+.. note:: The behavior is undefined if there are several rules for the same network.
+
+If there are multiple rules that match the same network all of them will be
+applied, which means that the smallest one wins, as it's bucket fills up the
+fastest.

+Objects and Paths
+~~~~~~~~~~~~~~~~~
+
+Access permissions are assigned to objects, such as a datastore, a namespace or
+some system resources.
+
+We use file system like paths to address these objects. These paths form a
+natural tree, and permissions of higher levels (shorter paths) can optionally
+be propagated down within this hierarchy.
+
+Paths can be templated, that means they can refer to the actual id of an
+configuration entry.  When an API call requires permissions on a templated
+path, the path may contain references to parameters of the API call. These
+references are specified in curly braces.
+
+Some examples are:
+
+* `/datastore`: Access to *all* datastores on a Proxmox Backup server
+* `/datastore/{store}`: Access to a specific datastore on a Proxmox Backup
+  server
+* `/datastore/{store}/{ns}`: Access to a specific namespace on a specific
+  datastore
+* `/remote`: Access to all remote entries
+* `/system/network`: Access to configuring the host network
+* `/tape/`: Access to tape devices, pools and jobs
+* `/access/users`: User administration
+* `/access/openid/{id}`: Administrative access to a specific OpenID Connect realm
+
+Inheritance
+^^^^^^^^^^^
+
+As mentioned earlier, object paths form a file system like tree, and
+permissions can be inherited by objects down that tree through the propagate
+flag, which is set by default. We use the following inheritance rules:
+
+* Permissions for API tokens are always clamped to the one of the user.
+* Permissions on deeper, more specific levels replace those inherited from an
+  upper level.
