Before I go off testing that, I just want to mention that you're my
hero. :D Next to the actual authors of BackupPC, of course.
I've made so much use of your scripts it's not even funny; BackupPC
is great but it breaks down when you're trying to juggle super-large
clients (I have *one BackupPC client* with 2.3TiB in the pool)
around between various BackupPC hosts, and other crazy large-scale
crap. Your scripts have been invaluable.
