Single post in Daily backup failure + potential changes

I'm not sure entirely what changes have happened in the last day or so since this update was announced (I belive Niet mentioned the fix was to remove the shelter from being backed up) but I'd like to throw some numbers out that I saw with today's backup:

• Backup began at 10:12 and ended at 10:22 - only 10 minutes, not the previously estimated 20. Probably has something to do with the above-mentioned change.
• Only about 280 people were logged in at the time when backup began.
• The backup progression went pretty quickly until 64% completion, where it sat for the longest time (about 6 minutes). I wonder what happens at that stage? It went pretty quickly again after passing that point.

Just some things to think about, moving forward with this debate. If you can't tell I get pretty bored sometimes and document/pay attention to random things
