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 | ||
9 | ||
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. | |
22 | ||
23 | ||
24 | How long will my Proxmox Backup Server version be supported? | |

34 | Can I copy or synchronize my datastore to another location? | |
35 | ----------------------------------------------------------- | |
36 | ||
3bbb70b3 | 37 | Proxmox Backup Server allows you to copy or synchronize datastores to other |
1de47507 DW |
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. | |
42 | ||
43 | ||
44 | Can Proxmox Backup Server verify data integrity of a backup archive? | |
45 | -------------------------------------------------------------------- | |
46 | ||
e84fde3e TL |
47 | Proxmox Backup Server uses a built-in SHA-256 checksum algorithm, to ensure |
48 | data integrity. Within each backup, a manifest file (index.json) is created, | |
49 | which contains a list of all the backup files, along with their sizes and | |
50 | checksums. This manifest file is used to verify the integrity of each backup. | |

53 | When backing up to remote servers, do I have to trust the remote server? | |
54 | ------------------------------------------------------------------------ | |
55 | ||

56 | Proxmox Backup Server supports client-side encryption, meaning your data is |
57 | encrypted before it reaches the server. Thus, in the event that an attacker | |
58 | gains access to the 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 | |
3294b516 | 63 | of the Proxmox Backup Server Administration Guide. |

66 | Is the backup incremental/deduplicated? | |
67 | --------------------------------------- | |
68 | ||
e84fde3e TL |
69 | With Proxmox Backup Server, backups are sent incremental and data is |
70 | deduplicated on the server. | |
71 | This minimizes both the storage consumed and the network impact. |
