For this project, I used btrfs because it was quick to use as a proof-of-concept and I happened to be most familiar with it of the CoW-capable file systems. But pg_branch is easy to extend with other snapshot-capable fs (it's a single trait, internally, that someone would need to implement). Happy to accept pull requests for supporting e.g. ZFS or XFS.

Should presumably be possible to support bcachefs too?

  Any file system that can implement the Branching trait should be possible to support. The only assumption made is that "snapshots" (or whatever equivalent term applies for that file system) are atomic.
