Help me gather them?

btrbk

Backup utility using BTRFS

snapper

General system snapshot utility with BTRFS support, used in OpenSUSE Tumbleweed

butter-manager

Tool for managing snapshots, balancing filesystems and upgrading the system safetly.

    Maintaining btrfs is more work than maintaining ext4, which basically doesn’t need any. I.e. running btrfs scrub is important to keep performance up. Monthly scrubs are good because they don’t take as long if done regularly.

    Btrfs balance can free up some space, but otherwise isn’t important on SSDs.

      I think BTRFS is especially problematic on Fedora Atomic desktops.

      Afaik the OSTree snapshots use BTRFS deduplication, also the zstd compression helps reduce storage usage and increase SSD use.

      But as the entire system partitions are read only, you cant balance, scrub etc them.

      This is a big issue I think, I will open a Fedora Discussion post about this.

        Note: OSTree will transparently take advantage of some BTRFS features if deployed on it. [1]

        Interesting, I didn’t know OSTree takes advantage of BTRFS features.

        On my current system I use ext4 instead of btrfs which I regret specifically because of the missing transparent compression and reflink copy.
