OK, you ARE using disconnected IMAP. I have to read a little more carefully.

If it is for backup, why don't you copy the imap data over to a local
imap server? There are tools like imapsync and similar to handle this. I
set up a little server at home for this (ok, not only this but all kind
of sharing). And dovecot is easy to set up and uses maildir internally.
