cyrus backup
We're moving to cyrus so we can do all the nifty kolab stuff.
Right now we're studying how to get a good enough backup.
After discarding LVM snapshots and stopping the mail server, Our options
seem to be:
A) Do a 'hot' backup while the server is running
B) sync to another cyrus, stop that cyrus and back
it up.
Option A has the advantage of simplicity, We can reuse our courier
backup w/o problem. It has the disadvantage of backing up cyrus Berkley
db files in an inconsistent state. --We risk losing some state,
particularly the "seen" state of messages.
Option B has the disadvantage of complexity.
We have only about 300 mailboxes but expect to be at 1200 in a year or so.
Does anyone have experience with a full restore of a cyrus server from a
hot sloppy backup ?
From our small search-fu, we have a pretty good idea of how to do
either option. We're looking for more thought on why.
