erm, how do I back up solr data? is in that in couch as well?

can I backup mnesia just by copying /var/lib/rabbitmq/mnesia?  I have bad memories of working w/ mnesia from ejabberd.

Backing up your Solr data is not strictly required (you can run `knife index rebuild` to get it back), but may make for a smoother recovery. Similarly, your rabbitmq config (generally in var/lib/rabbitmq/mnesia/ or similar) can be recreated (and Chef generally won't touch it except in something like the bootstrap cookbook) but may be worth backing up as well.

And please do let us know about your experiences testing, both good and bad--it will help us decide when to go from beta to RC. For RCs, we've instituted a three day freeze policy where we wait for three days without a reported regression before shipping the final version.

Thanks in advance!
