I don't understand why he didn't pipe btrfs through network. Do a btrfs snapshot first, then btrfs send => nc => network => nc => brtfs receive. That way only blocks in use are sent.
- tarruda 3y agoThat's the first thing I thought when I saw he used btrfs. I use btrfs send/receive all the time via SSH and it works great. He could easily have setup SSH server in GRML live session. There's one caveat though: With btrfs it is not possible to send snapshots recursively, so if he had lots of recursive snapshots (which can happen in Docker/LXD/Incus), it is relatively hard to mirror the same structure in a new disk. I like btrfs, but recursive send/receive is one aspect ZFS is just better.
- streb-lo 3y agoYea, there needs to be a `snapshot -r` option or something. I like using subvolumes to manage what gets a snapshot but sometimes you want the full disk.
