Selfhosted backup server and open source client

• BorgBackup

  333 10,526 9.4 Python

  Deduplicating archiver with compression and authenticated encryption.

  

I have used two different tools: Borg, which I have used for several years. It works very well over SSH and has good configurability in all areas, from file exclusions to retention configs. It does deduplication and client side encryption.

• restic

  357 23,766 9.7 Go

  Fast, secure, efficient backup program

  

The only reason I switched away from it was that I'm now running a Ceph cluster and wanted to back up to one of it's pools via S3. So now I'm using Restic. It has a far wider variety of backup targets, including local disk and S3. Similar to Borg, it does deduplication and does encryption.

• UrBackup

  56 615 5.5 C

  UrBackup - Client/Server Open Source Network Backup for Windows, MacOS and Linux

• btrfs

  220 5,280 8.4 C

  WinBtrfs - an open-source btrfs driver for Windows

For other OSes, I'm not really sure. I think they don't support those for their system drives but I guess it should be possible to get them to work for data drives somehow (e.g., https://github.com/maharmstone/btrfs).
