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 synchronize 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 transfers data via `Transport Layer Security (TLS)
|
|
<https://en.wikipedia.org/wiki/Transport_Layer_Security>`_ and additionally
|
|
supports client-side encryption. This means that data is transferred securely
|
|
and can be encrypted before it reaches the server. Thus, in the event that an
|
|
attacker gains access to the server or any point of the network, they will not
|
|
be able to read the data.
|
|
|
|
.. note:: Encryption is not enabled by default. To set up encryption, see the
|
|
:ref:`backup client encryption section <client_encryption>`.
|
|
|
|
|
|
Is the backup incremental/deduplicated/full?
|
|
--------------------------------------------
|
|
|
|
With Proxmox Backup Server, backups are sent incrementally to the server, and
|
|
data is then deduplicated on the server. This minimizes both the storage
|
|
consumed and the impact on the network. Each backup still references all
|
|
data and such is a full backup. For details see the
|
|
:ref:`Technical Overview <tech_design_overview>`
