Terminology
|
|
-----------
|
|
|
|
Backup Type
|
|
~~~~~~~~~~~
|
|
|
|
The backup server groups backups by *type*, where *type* is one of:
|
|
|
|
``vm``
|
|
This type is use for :term:`virtual machine`\ s. Typically
|
|
contains the virtual machine configuration and an image archive
|
|
for each disk.
|
|
|
|
``ct``
|
|
This type is use for :term:`container`\ s. Contains the container
|
|
configuration and a single file archive for the container content.
|
|
|
|
``host``
|
|
This type is used for physical host, or if you want to run backup
|
|
manually from inside virtual machines or containers. Such backup
|
|
may contains file and image archives (no restrictions here).
|
|
|
|
|
|
Backup ID
|
|
~~~~~~~~~
|
|
|
|
An unique ID. Usually the virtual machine or container ID. ``host``
|
|
type backups normally use the hostname.
|
|
|
|
|
|
Backup Time
|
|
~~~~~~~~~~~
|
|
|
|
The time when the backup was made.
|
|
|
|
|
|
Backup Snapshot
|
|
~~~~~~~~~~~~~~~
|
|
|
|
We call the triplet ``<type>/<ID>/<time>`` a backup snapshot. It
|
|
uniquely identifies a specific backup within a datastore.
|
|
|
|
.. code-block:: console
|
|

vm/104/2019-10-09T08:01:06Z
|
|
host/elsa/2019-11-08T09:48:14Z
|
|
|
|
As you can see, the time is formatted as RFC3399_ using Coordinated
|
|
Universal Time (UTC_, identified by the trailing *Z*).
|
|
|
|
|
|
:term:`DataStore`
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
A datastore is a place to store backups. The current implementation
|
|
uses a directory inside a standard unix file system (``ext4``, ``xfs``
|
|
or ``zfs``) to store backup data.
|
|
|
|
Datastores are identified by a simple *ID*. You can configure that
|
|
when setting up the backup server.
|
|
|
|
|
|
Backup Server Management
|
|
------------------------
|
|
|
|
The command line tool to configure and manage the server is called
|
|
:command:`proxmox-backup-manager`.
|
|
|
|
|
|
Datastore Configuration
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
A :term:`datastore` is a place to store backups. You can configure
|
|
several datastores, but you need at least one of them. The datastore is identified by a simple `name` and point to a directory.
|
|
|
|
The following command creates a new datastore called ``store1`` on :file:`/backup/disk1/store1`
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager datastore create store1 /backup/disk1/store1
|
|
|
|
To list existing datastores use:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager datastore list
|
|
store1 /backup/disk1/store1
|
|
|
|
Finally, it is also possible to remove the datastore configuration:
|
|
|
|
.. code-block:: console
|
|
|
|
# proxmox-backup-manager datastore remove store1
|
|
|
|
.. note:: Above command removes the datastore configuration. It does
|
|
not delete any data from the underlying directory.
|
|
|
|
|
|
File Layout
|
|
^^^^^^^^^^^

|
|
|
.. todo:: Add datastore file layout example
|
|
|

|
Backup Client usage
|
|
-------------------
|
|
|
|
The command line client is called :command:`proxmox-backup-client`.
|
|
|
|
Respository Locations
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The client uses a special repository notation to specify a datastore
|
|
on the backup server.
|
|
|
|
[[username@]server:]datastore
|
|
|
|
If you do not specify a ``username`` the default is ``root@pam``. The
|
|
default for server is to use the local host (``localhost``).
|
|
|
|
You can pass the repository by setting the ``--repository`` command
|
|
line options, or by setting the ``PBS_REPOSITORY`` environment
|
|
variable.
|
|
|
|
|
|
Environment Variables
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
``PBS_REPOSITORY``
|
|
The default backup repository.
|
|
|
|
``PBS_PASSWORD``
|
|
When set, this value is used for the password required for the
|
|
backup server.
|
|
|
|
``PBS_ENCRYPTION_PASSWORD``
|
|
|
|
When set, this value is used to access the secret encryption key (if
|
|
protected by password).
