4 What distribution is Proxmox Backup Server (PBS) based on?
5 ----------------------------------------------------------
6
7 Proxmox Backup Server is based on `Debian GNU/Linux <https://www.debian.org/>`_.
8

10 Which platforms are supported as a backup source (client)?
11 ----------------------------------------------------------
12
13 The client tool works on most modern Linux systems, meaning you are not limited
14 to Debian-based backups.
15
16
17 Will Proxmox Backup Server run on a 32-bit processor?
18 -----------------------------------------------------
19
20 Proxmox Backup Server only supports 64-bit CPUs (AMD or Intel). There are no
21 future plans to support 32-bit processors.

34 Can I copy or synchronize my datastore to another location?
35 -----------------------------------------------------------
36
37 Proxmox Backup Server allows you to copy or synchroize datastores to other
38 locations, through the use of *Remotes* and *Sync Jobs*. *Remote* is the term
39 given to a separate server, which has a datastore that can be synced to a local store.
40 A *Sync Job* is the process which is used to pull the contents of a datastore from
41 a *Remote* to a local datastore.

43
44 Can Proxmox Backup Server verify data integrity of a backup archive?
45 --------------------------------------------------------------------
46
47 PBS uses a built-in SHA-256 checksum algorithm, to ensure data integrity. Within
48 each backup, a manifest file (index.json) is created, which contains a list of
49 all the backup files, along with their sizes and checksums. This manifest file
50 is used to verify the integrity of each backup.
51
52
53 When backing up to remote servers, do I have to trust the remote server?
54 ------------------------------------------------------------------------
55
56 PBS supports client-side encryption, meaning your data is encrypted before
57 it reaches the server. Thus, in the event that an attacker gains access to the
58 server, they will not be able to read the data.
59
60 .. note:: Encryption is not enabled by default. To set up encryption, see the
61 `Encryption
62 <https://pbs.proxmox.com/docs/administration-guide.html#encryption>`_ section
63 of the PBS Administration Guide.

65
66 Is the backup incremental/deduplicated?
67 ---------------------------------------
68
69 With PBS, backups are incremental and data is deduplicated. This minimizes both
70 the storage consumed and the network impact.
