# Work around OpenSims slow database corruption bug by using git to store all old backups.
# Try to squeeze every last byte out of the tarballs. Seems to cut the total storage size down to one third the size of just the raw I/OAR files.
# Saves even more if there's been no changes.
# On the other hand, these backup files will grow indefinately, the more changes, the faster it grows. I can live with that for more reliable backups that go back further.
# Tries to avoid loosing data if things go wrong. I think the main remaining problem would be running out of space, in which case you have bigger problems to deal with.
# Strategy - unpack the last one, unpack and commit any old I/OARs, pack up the result, delete it's working directory, THEN run the save i/oar.
# Avoids having to sync with OpenSim finishing the current I/OAR, and as a bonus, an easy to deliver latest I/OAR for people that want it.
# Not really meant to be called by users, so don't bother validating the input and such.
