You could do it with dsync.
dsync seems to do a marvelous job - new question.?
Given a mailbox with a larger number of older mails - assuming any new
mails will have later dates - will the new mail storage files be
identical? I'm probably not saying the right - let me try this:
1. "dsync backup mdbox" (with appropriate args) is run for a given user.
2. "dsync mirror mdbox" is done just to catch up.
3. Old mailstore moved off.
4. New mailstore moved to active location.
I'm sure there's a safer way to do the above - but I've got a
low-traffic site and I can just shut down mail service altogether for
a few minutes if I want during this.
Now - repeat the above four steps. Will mail files m.1 through
m.(n-1) be identical to the last run? Is this a valid packing
strategy prior to performing an rsync type backup - assuming no
changes are being made to the archived mails between pack runs?
Given the above, and SIS - if the backup is performed in the same spool,
i.e. original is /var/mail/domain/user, backup is
/var/mail/domain/user-new - will this result in any problems with SIS?
If after the pack and rename operation, the old mail tree is simply
deleted - will that leave SIS files unreferenced if the user later
deletes the messages from their active store?
