No one proposed that. The scenario is that the backup server would have its rsync destination dir (from multiple other systems) periodically snapshotted, providing a historic view of what it contained 1-2-3 months ago.

But now we have that directly in filesystem, no need to cling to userspace crutches anymore. -- With respect, Roman
