Summary	0000565: use btrfs features to efficiently detect changed files
Description	btrfs (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 Information	btrfs 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?).
Tags	No tags attached.

mdc 2024-03-25 11:28 reporter ~0005865	I think ZFS will be possible using libzfs_core which comes with the ZFS distribution for any linux. And provides the needed hight level functions for snapshots and send/receive it.

bruno-at-bareos 2024-03-27 15:08 manager ~0005875	We're closing this issue: it may become a feature request (with proper sponsoring) in the soon opened gthub issues and feature system.
