| 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? | |
| 25 | ------------------------------------------------------------ | |

| 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. | |
| 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 | ------------------------------------------------------------------------ | |

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. |
