From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Filesystem mirroring: best backup tool? (feddit.de)

I am currently using Freefilesync Flatpak, but that app is not great at all. I dont want weird archives or anything, just to copy my filesystem to another drive.

Also, I want to mirror with the possibility to exclude folders. Mirroring means that the backup should be updated to look like my disk, including deletion of files.

I tested many tools in the Past and for some reason came back to FFS.

Best would be to have automatic backups once I plug in and decrypt the backup drive.

Thanks!

So many options. As others have mentioned, rsync, borg, restic, etc. You might want to look into filesystem snapshots. If you use something like BTRFS you can create instant snapshots and send them to a second BTRFS formatted disk or even a remote system with a BTRFS filesystem.

ZFS would also work here.

I use btrbk for automatic BTRFS snapshots and backing them up to remote systems.

If you want built-in encryption you can use Borg or Restic, which also has the advantage of deduplicating within a single backup set. Restic can also backup to an s3 bucket, in case you want to use a cloud service.

Thanks! I have a local drive, does btrbk work there too?

I am on Fedora so BTRFS ftw

Yes of course. On the btrbk homepage they even describe how to set it up so that a backup gets triggered automatically when you plug in a designated backup drive.

My setup is to create local snapshots and keep X amount of local snapshots. Copy snapshots to a remote server and keep a different amount of snapshots there. Finally I also have a backup drive and btrbk is setup to copy all my local snapshots to that backup drive when it's plugged in.
