| 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? | |

| 36 | Can I copy or synchronize my datastore to another location? | |
| 37 | ----------------------------------------------------------- | |
| 38 | ||
| 3bbb70b3 | 39 | Proxmox Backup Server allows you to copy or synchronize datastores to other |
| 1de47507 DW |
40 | locations, through the use of *Remotes* and *Sync Jobs*. *Remote* is the term |
| 41 | given to a separate server, which has a datastore that can be synced to a local store. | |
| 42 | A *Sync Job* is the process which is used to pull the contents of a datastore from | |
| 43 | a *Remote* to a local datastore. | |
| 44 | ||
| 45 | ||
| 46 | Can Proxmox Backup Server verify data integrity of a backup archive? | |
| 47 | -------------------------------------------------------------------- | |
| 48 | ||
| e84fde3e TL |
49 | Proxmox Backup Server uses a built-in SHA-256 checksum algorithm, to ensure |
| 50 | data integrity. Within each backup, a manifest file (index.json) is created, | |
| 51 | which contains a list of all the backup files, along with their sizes and | |
| 52 | checksums. This manifest file is used to verify the integrity of each backup. | |

| 55 | When backing up to remote servers, do I have to trust the remote server? | |
| 56 | ------------------------------------------------------------------------ | |

58 | Proxmox Backup Server transfers data via `Transport Layer Security (TLS) |
| 59 | <https://en.wikipedia.org/wiki/Transport_Layer_Security>`_ and additionally | |
| 60 | supports client-side encryption. This means that data is transferred securely | |
| 61 | and can be encrypted before it reaches the server. Thus, in the event that an | |
| 62 | attacker gains access to the server or any point of the network, they will not | |
| 63 | be able to read the data. | |
| 1de47507 DW |
64 | |
| 65 | .. note:: Encryption is not enabled by default. To set up encryption, see the | |
| 384a2b4d | 66 | :ref:`backup client encryption section <client_encryption>`. |

| d8e4837a | 69 | Is the backup incremental/deduplicated/full? |
| ae66b245 | 70 | -------------------------------------------- |
| 1de47507 | 71 | |
| 2bc1250c DW |
72 | With Proxmox Backup Server, backups are sent incrementally to the server, and |
| 73 | data is then deduplicated on the server. This minimizes both the storage | |
| d8e4837a DC |
74 | consumed and the impact on the network. Each backup still references all |
| 75 | data and such is a full backup. For details see the | |
| 76 | :ref:`Technical Overview <tech_design_overview>` |
