Crazy? Perhaps, but rsync'ing shouldn't cause any problems because
of the unique file names, and it's --delete option should preserve
the Maildir structure across to the "mirror" server, right? Our
main office only has about 100 employee's, so the T1 bandwidth
should suffice...
If one of the lines goes down and everyone switches over to using the
rsync-ed mailboxes on the other server, then when service is restored
the first rsync will obliterate any changes made to the rsync-ed
copies of the mailboxes.
I'll have to do something creative to not allow that to happen, maybe
something with rsync's --include to have the server's only mirror what
it's delivered (as the hostname is in the filename...). I'll sort that
out later...
Or, it's possible that a fractional T1 between the two offices may be
cheaper than a pair of backup low-bandwidth circuits. Except that a
backhoe incident in the immediate neighborhood will likely take out
both circuits.
I should clarify - it's been mandated that I put a server in the remote
location... or else we move to Exchange.
Folks in the remote office, about 25 users all using IMAP via Outlook
2000, were seeing intermitent response degradation, the cause of which
I have been unable to pinpoint. The frustration level has gotten pretty
high there, so it has been decided they get their own server.
