+Calendar Events
+===============
+
+Introduction and Format
+-----------------------
+
+Certain tasks, for example pruning and garbage collection, need to be
+performed on a regular basis. Proxmox Backup Server uses a format inspired
+by the systemd Time and Date Specification (see `systemd.time manpage`_)
+called `calendar events` for its schedules.
+
+`Calendar events` are expressions to specify one or more points in time.
+They are mostly compatible with systemds calendar events.
+
+The general format is as follows:
+
+.. code-block:: console
+  :caption: Calendar event
+
+  [WEEKDAY] [[YEARS-]MONTHS-DAYS] [HOURS:MINUTES[:SECONDS]]
+
+Note that there either has to be at least a weekday, date or time part.
+If the weekday or date part is omitted, all (week)days are included.
+If the time part is omitted, the time 00:00:00 is implied.
+(e.g. '2020-01-01' refers to '2020-01-01 00:00:00')
+
+Weekdays are specified with the abbreviated english version:
+`mon, tue, wed, thu, fri, sat, sun`.
+
+Each field can contain multiple values in the following formats:
+
+* comma-separated: e.g.,  01,02,03
+* as a range: e.g., 01..10
+* as a repetition: e.g, 05/10 (means starting at 5 every 10)
+* and a combination of the above: e.g., 01,05..10,12/02
+* or a `*` for every possible value: e.g., \*:00
+
+There are some special values that have specific meaning:
+
+=================================  ==============================
+Value                              Syntax
+=================================  ==============================
+`minutely`                         `*-*-* *:*:00`
+`hourly`                           `*-*-* *:00:00`
+`daily`                            `*-*-* 00:00:00`
+`weekly`                           `mon *-*-* 00:00:00`
+`monthly`                          `*-*-01 00:00:00`
+`yearly` or `annualy`              `*-01-01 00:00:00`
+`quarterly`                        `*-01,04,07,10-01 00:00:00`

+======================== =============================  ===================================
+
+
+Differences to systemd
+----------------------
+
+Not all features of systemd calendar events are implemented:
+
+* no unix timestamps (e.g. `@12345`): instead use date and time to specify
+  a specific point in time
+* no timezone: all schedules use the set timezone on the server
+* no sub-second resolution
+* no reverse day syntax (e.g. 2020-03~01)
+* no repetition of ranges (e.g. 1..10/2)
+
+Notes on scheduling
+-------------------
+
+In `Proxmox Backup`_ scheduling for most tasks is done in the
+`proxmox-backup-proxy`. This daemon checks all job schedules
+if they are due every minute. This means that even if
+`calendar events` can contain seconds, it will only be checked
+once a minute.
+
+Also, all schedules will be checked against the timezone set
+in the `Proxmox Backup`_ server.

+FAQ
+===
+
+What distribution is Proxmox Backup Server (PBS) based on?
+----------------------------------------------------------
+
+Proxmox Backup Server is based on `Debian GNU/Linux <https://www.debian.org/>`_.
+
+
+Which platforms are supported as a backup source (client)?
+----------------------------------------------------------
+
+The client tool works on most modern Linux systems, meaning you are not limited
+to Debian-based backups.
+
+
+Will Proxmox Backup Server run on a 32-bit processor?
+-----------------------------------------------------
+
+Proxmox Backup Server only supports 64-bit CPUs (AMD or Intel). There are no
+future plans to support 32-bit processors.
+
+
+How long will my Proxmox Backup Server version be supported?
+------------------------------------------------------------
+
++-----------------------+--------------------+---------------+------------+--------------------+
+|Proxmox Backup Version | Debian Version     | First Release | Debian EOL | Proxmox Backup EOL |
++=======================+====================+===============+============+====================+
+|Proxmox Backup 1.x     | Debian 10 (Buster) | tba           | tba        | tba                |
++-----------------------+--------------------+---------------+------------+--------------------+
+
+
+Can I copy or synchronize my datastore to another location?
+-----------------------------------------------------------
+
+Proxmox Backup Server allows you to copy or synchroize datastores to other
+locations, through the use of *Remotes* and *Sync Jobs*. *Remote* is the term
+given to a separate server, which has a datastore that can be synced to a local store.
+A *Sync Job* is the process which is used to pull the contents of a datastore from
+a *Remote* to a local datastore.
+
+
+Can Proxmox Backup Server verify data integrity of a backup archive?
+--------------------------------------------------------------------
+
+Proxmox Backup Server uses a built-in SHA-256 checksum algorithm, to ensure
+data integrity. Within each backup, a manifest file (index.json) is created,
+which contains a list of all the backup files, along with their sizes and
+checksums. This manifest file is used to verify the integrity of each backup.
+
+
+When backing up to remote servers, do I have to trust the remote server?
+------------------------------------------------------------------------
+
+Proxmox Backup Server supports client-side encryption, meaning your data is
+encrypted before it reaches the server. Thus, in the event that an attacker
+gains access to the server, they will not be able to read the data.
+
+.. note:: Encryption is not enabled by default. To set up encryption, see the
+  `Encryption
+  <https://pbs.proxmox.com/docs/administration-guide.html#encryption>`_ section
+  of the Proxmox Backup Server Administration Guide.
+
+
+Is the backup incremental/deduplicated?
+---------------------------------------
+
+With Proxmox Backup Server, backups are sent incremental and data is
+deduplicated on the server.
+This minimizes both the storage consumed and the network impact.

 Software Stack
 --------------
 
-.. todo:: Eplain why we use Rust (and Flutter)
+Proxmox Backup Server consists of multiple components:
-	  
+
+* A server-daemon providing, among other things, a RESTfull API, super-fast
+  asynchronous tasks, lightweight usage statistic collection, scheduling
+  events, strict separation of privileged and unprivileged execution
+  environments
+* A JavaScript management web interface
+* A management CLI tool for the server (`proxmox-backup-manager`)
+* A client CLI tool (`proxmox-backup-client`) to access the server easily from
+  any `Linux amd64` environment
+
+Aside from the web interface, everything is written in the Rust programming
+language.
+
+ "The Rust programming language helps you write faster, more reliable software.
+ High-level ergonomics and low-level control are often at odds in programming
+ language design; Rust challenges that conflict. Through balancing powerful
+ technical capacity and a great developer experience, Rust gives you the option
+ to control low-level details (such as memory usage) without all the hassle
+ traditionally associated with such control."

+ZFS on Linux
+------------
+
+ZFS is a combined file system and logical volume manager designed by
+Sun Microsystems. There is no need to manually compile ZFS modules - all
+packages are included.
+
+By using ZFS, it's possible to achieve maximum enterprise features with
+low budget hardware, but also high performance systems by leveraging
+SSD caching or even SSD only setups. ZFS can replace cost intense
+hardware raid cards by moderate CPU and memory load combined with easy
+management.
+
+General ZFS advantages
+
+* Easy configuration and management with GUI and CLI.
+* Reliable
+* Protection against data corruption
+* Data compression on file system level
+* Snapshots
+* Copy-on-write clone
+* Various raid levels: RAID0, RAID1, RAID10, RAIDZ-1, RAIDZ-2 and RAIDZ-3
+* Can use SSD for cache
+* Self healing
+* Continuous integrity checking
+* Designed for high storage capacities
+* Asynchronous replication over network
+* Open Source
+* Encryption
+
+Hardware
+~~~~~~~~~
+
+ZFS depends heavily on memory, so you need at least 8GB to start. In
+practice, use as much you can get for your hardware/budget. To prevent
+data corruption, we recommend the use of high quality ECC RAM.
+
+If you use a dedicated cache and/or log disk, you should use an
+enterprise class SSD (e.g. Intel SSD DC S3700 Series). This can
+increase the overall performance significantly.
+
+IMPORTANT: Do not use ZFS on top of hardware controller which has its
+own cache management. ZFS needs to directly communicate with disks. An
+HBA adapter is the way to go, or something like LSI controller flashed
+in ``IT`` mode.
+
+
+ZFS Administration
+~~~~~~~~~~~~~~~~~~
+
+This section gives you some usage examples for common tasks. ZFS
+itself is really powerful and provides many options. The main commands
+to manage ZFS are `zfs` and `zpool`. Both commands come with great
+manual pages, which can be read with:
+
+.. code-block:: console
+
+  # man zpool
+  # man zfs
+
+Create a new zpool
+^^^^^^^^^^^^^^^^^^
+
+To create a new pool, at least one disk is needed. The `ashift` should
+have the same sector-size (2 power of `ashift`) or larger as the
+underlying disk.
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> <device>
+
+Create a new pool with RAID-0
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

+
+Add cache and log to an existing pool
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you have a pool without cache and log. First partition the SSD in
+2 partition with `parted` or `gdisk`
+
+.. important:: Always use GPT partition tables.
+
+The maximum size of a log device should be about half the size of
+physical memory, so this is usually quite small. The rest of the SSD
+can be used as cache.
+
+.. code-block:: console
+
+  # zpool add -f <pool> log <device-part1> cache <device-part2>
+
+
+Changing a failed device
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: console
+
+  # zpool replace -f <pool> <old device> <new device>
+
+
+Changing a failed bootable device
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Depending on how Proxmox Backup was installed it is either using `grub` or `systemd-boot`
+as bootloader.
+
+The first steps of copying the partition table, reissuing GUIDs and replacing
+the ZFS partition are the same. To make the system bootable from the new disk,
+different steps are needed which depend on the bootloader in use.
+
+.. code-block:: console
+
+  # sgdisk <healthy bootable device> -R <new device>
+  # sgdisk -G <new device>
+  # zpool replace -f <pool> <old zfs partition> <new zfs partition>
+
+.. NOTE:: Use the `zpool status -v` command to monitor how far the resilvering process of the new disk has progressed.
+
+With `systemd-boot`:
+
+.. code-block:: console
+
+  # pve-efiboot-tool format <new disk's ESP>
+  # pve-efiboot-tool init <new disk's ESP>
+
+.. NOTE:: `ESP` stands for EFI System Partition, which is setup as partition #2 on
+  bootable disks setup by the {pve} installer since version 5.4. For details, see
+  xref:sysboot_systemd_boot_setup[Setting up a new partition for use as synced ESP].
+
+With `grub`:
+
+Usually `grub.cfg` is located in `/boot/grub/grub.cfg`
+
+.. code-block:: console
+
+  # grub-install <new disk>
+  # grub-mkconfig -o /path/to/grub.cfg
+
+
+Activate E-Mail Notification
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ZFS comes with an event daemon, which monitors events generated by the
+ZFS kernel module. The daemon can also send emails on ZFS events like
+pool errors. Newer ZFS packages ship the daemon in a separate package,
+and you can install it using `apt-get`:
+
+.. code-block:: console
+
+  # apt-get install zfs-zed
+
+To activate the daemon it is necessary to edit `/etc/zfs/zed.d/zed.rc` with your
+favourite editor, and uncomment the `ZED_EMAIL_ADDR` setting:
+
+.. code-block:: console
+
+  ZED_EMAIL_ADDR="root"
+
+Please note Proxmox Backup forwards mails to `root` to the email address
+configured for the root user.
+
+IMPORTANT: The only setting that is required is `ZED_EMAIL_ADDR`. All
+other settings are optional.
+
+Limit ZFS Memory Usage
+^^^^^^^^^^^^^^^^^^^^^^
+
+It is good to use at most 50 percent (which is the default) of the
+system memory for ZFS ARC to prevent performance shortage of the
+host. Use your preferred editor to change the configuration in
+`/etc/modprobe.d/zfs.conf` and insert:
+
+.. code-block:: console
+
+  options zfs zfs_arc_max=8589934592
+
+This example setting limits the usage to 8GB.
+
+.. IMPORTANT:: If your root file system is ZFS you must update your initramfs every time this value changes:
+
+.. code-block:: console
+
+  # update-initramfs -u
+
+
+SWAP on ZFS
+^^^^^^^^^^^
+
+Swap-space created on a zvol may generate some troubles, like blocking the
+server or generating a high IO load, often seen when starting a Backup
+to an external Storage.
+
+We strongly recommend to use enough memory, so that you normally do not
+run into low memory situations. Should you need or want to add swap, it is
+preferred to create a partition on a physical disk and use it as swapdevice.
+You can leave some space free for this purpose in the advanced options of the
+installer. Additionally, you can lower the `swappiness` value. 
+A good value for servers is 10:
+
+.. code-block:: console
+
+  # sysctl -w vm.swappiness=10
+
+To make the swappiness persistent, open `/etc/sysctl.conf` with
+an editor of your choice and add the following line:
+
+.. code-block:: console
+
+  vm.swappiness = 10
+
+.. table:: Linux kernel `swappiness` parameter values
+  :widths:auto
+
+  ====================  ===============================================================
+   Value                Strategy
+  ====================  ===============================================================
+   vm.swappiness = 0    The kernel will swap only to avoid an 'out of memory' condition
+   vm.swappiness = 1    Minimum amount of swapping without disabling it entirely.
+   vm.swappiness = 10   Sometimes recommended to improve performance when sufficient memory exists in a system.
+   vm.swappiness = 60   The default value.
+   vm.swappiness = 100  The kernel will swap aggressively.
+  ====================  ===============================================================
+
+ZFS Compression
+^^^^^^^^^^^^^^^
+
+To activate compression:
+.. code-block:: console
+
+  # zpool set compression=lz4 <pool>
+
+We recommend using the `lz4` algorithm, since it adds very little CPU overhead.
+Other algorithms such as `lzjb` and `gzip-N` (where `N` is an integer `1-9` representing
+the compression ratio, 1 is fastest and 9 is best compression) are also available.
+Depending on the algorithm and how compressible the data is, having compression enabled can even increase
+I/O performance.
+
+You can disable compression at any time with:
+.. code-block:: console
+
+  # zfs set compression=off <dataset>
+
+Only new blocks will be affected by this change.
+
+ZFS Special Device
+^^^^^^^^^^^^^^^^^^
+
+Since version 0.8.0 ZFS supports `special` devices. A `special` device in a
+pool is used to store metadata, deduplication tables, and optionally small
+file blocks.
+
+A `special` device can improve the speed of a pool consisting of slow spinning
+hard disks with a lot of metadata changes. For example workloads that involve
+creating, updating or deleting a large number of files will benefit from the
+presence of a `special` device. ZFS datasets can also be configured to store
+whole small files on the `special` device which can further improve the
+performance. Use fast SSDs for the `special` device.
+
+.. IMPORTANT:: The redundancy of the `special` device should match the one of the
+  pool, since the `special` device is a point of failure for the whole pool.
+
+.. WARNING:: Adding a `special` device to a pool cannot be undone!
+
+Create a pool with `special` device and RAID-1:
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> mirror <device1> <device2> special mirror <device3> <device4>
+
+Adding a `special` device to an existing pool with RAID-1:
+
+.. code-block:: console
+
+  # zpool add <pool> special mirror <device1> <device2>
+
+ZFS datasets expose the `special_small_blocks=<size>` property. `size` can be
+`0` to disable storing small file blocks on the `special` device or a power of
+two in the range between `512B` to `128K`. After setting the property new file
+blocks smaller than `size` will be allocated on the `special` device.
+
+.. IMPORTANT:: If the value for `special_small_blocks` is greater than or equal to
+  the `recordsize` (default `128K`) of the dataset, *all* data will be written to
+  the `special` device, so be careful!
+
+Setting the `special_small_blocks` property on a pool will change the default
+value of that property for all child ZFS datasets (for example all containers
+in the pool will opt in for small file blocks).
+
+Opt in for all file smaller than 4K-blocks pool-wide:
+
+.. code-block:: console
+
+  # zfs set special_small_blocks=4K <pool>
+
+Opt in for small file blocks for a single dataset:
+
+.. code-block:: console
+
+  # zfs set special_small_blocks=4K <pool>/<filesystem>
+
+Opt out from small file blocks for a single dataset:
+
+.. code-block:: console
+
+  # zfs set special_small_blocks=0 <pool>/<filesystem>
+
+Troubleshooting
+^^^^^^^^^^^^^^^
+
+Corrupted cachefile
+
+In case of a corrupted ZFS cachefile, some volumes may not be mounted during
+boot until mounted manually later.
+
+For each pool, run:
+
+.. code-block:: console
+
+  # zpool set cachefile=/etc/zfs/zpool.cache POOLNAME
+
+and afterwards update the `initramfs` by running:
+
+.. code-block:: console
+
+  # update-initramfs -u -k all
+
+and finally reboot your node.
+
+Sometimes the ZFS cachefile can get corrupted, and `zfs-import-cache.service`
+doesn't import the pools that aren't present in the cachefile.
+
+Another workaround to this problem is enabling the `zfs-import-scan.service`,
+which searches and imports pools via device scanning (usually slower).

+//! We have [`Username`]s and [`Realm`]s. To uniquely identify a user, they must be combined into a [`Userid`].
+//!
+//! Since they're all string types, they're organized as follows:
+//!
+//! * [`Username`]: an owned user name. Internally a `String`.
+//! * [`UsernameRef`]: a borrowed user name. Pairs with a `Username` the same way a `str` pairs
+//!   with `String`, meaning you can only make references to it.
+//! * [`Realm`]: an owned realm (`String` equivalent).
+//! * [`RealmRef`]: a borrowed realm (`str` equivalent).
+//! * [`Userid`]: an owned user id (`"user@realm"`). Note that this does not have a separate
+//!   borrowed type.
+//!
+//! Note that `Username`s are not unique, therefore they do not implement `Eq` and cannot be
+//! compared directly. If a direct comparison is really required, they can be compared as strings
+//! via the `as_str()` method. [`Realm`]s and [`Userid`]s on the other hand can be compared with
+//! each other, as in those two cases the comparison has meaning.
