+# 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.
