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?

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?
|
||
|
|
--------------------------------------------------------------------
|
||
|
|
|
||
|
|
PBS 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?
|
||
|
|
------------------------------------------------------------------------
|
||
|
|
|
||
|
|
PBS 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 PBS Administration Guide.

|
Is the backup incremental/deduplicated?
|
||
|
|
---------------------------------------
|
||
|
|
|
||
|
|
With PBS, backups are incremental and data is deduplicated. This minimizes both
|
||
|
|
the storage consumed and the network impact.
