That depends on what kind of mailbox format you have. If you're using
maildirs or something similar, you're in luck. If you're still using
mboxes, you may have locking issues. If an email comes in while you're
in the middle of backing stuff up, you could have a mailbox whose
partial contents you're saving into your backup. It will be a corrupt
mbox with a portion of the mail at the end, easily recoverable, but a
damned nuisance. It would be safer to shut down mail service while you
back up in that case; at any rate, any decent MTA attempting to send
mail to your system while it's down will have the sense to queue the
mail and then try again a few hours later, by which time your backup
should be done. I seriously doubt that you have more than a thousand
users and even if you do I doubt that more than a few of them will
consume more than a couple megabytes of mail at any given time, so the
backup process may take more like a few minutes.
