Which begs another question that I've struggled a bit with lately.
I've considered making a series of snapshots by using --link-dest, and
moving(/copying) the backup directory prior to (in between) each run.
Once that's done, and there are several snapshots and thus files with
link counts of up to the number of snapshots, how can I tell how much
space is being used by all of the snapshots (and current backup) put
together, counting each file only once. du doesn't appear to cut it. ;)
I think I have a solution, but am curious to know what others may think
of the problem.
