Summary0000565: use btrfs features to efficiently detect changed files
Descriptionbtrfs (a default filesystem on SLES 12) provides features to generate a list of changed files between snapshots. This can be useful for Bareos to efficiently generate the file lists for Incremental and Differential backups.
Additional Informationbtrfs send operation compares two subvolumes and writes a description of how to convert one subvolume (the parent subvolume) into the other (the sent subvolume).
btrfs receive does the opposite.

SLES 12 comes the the tool snapper, which provides an abstraction for this functionality (and should work in the same way for LVM and ext4?).

6years later any news or plans for that?
the same can be done with zfs and bcachefs (in near feature)

so it would be great if bareos can support zfs/btrfs/bcachefs send/receive/snapshot

Note :
+ To work the snapshot has to be configured and run on time for the desired FS (use a subvolume + disk space)
+ To be benchmarked on heavily used FS compared to traditional Accurate module.
+ Think that Accurate is needed in AI
