While I agree that the issue involving Timeshift, BTRFS, and subvolumes needs to be addressed, it is important to clarify that this problem only affects the use of Timeshift with BTRFS snapshots. It does not impact the use of Timeshift with rsync. If users encounter this issue and have formatted their drive with BTRFS, they can opt to use rsync instead of BTRFS snapshots as a fallback.
