(...once again me with my rsync :)
If you didn't use send/receive, you wouldn't be required to keep a separate
snapshot trail per filesystem backed up, one trail of snapshots for the entire
backup server would be enough. Rsync everything to subdirs within one
subvolume, then do timed or event-based snapshots of it. You only need more
than one trail if you want different retention policies for different datasets
(e.g. in my case I have 91 and 31 days).
