For the duplicates , when an email is flagged , am working on a script that will remove the duplicates.
Am thinking about the following files: dovecot.index dovecot.index.cache dovecot.index.log maildirsize subscriptions dovecot-uidlist
Will they affect the restore process ??

The main potential problem with that is that if a message's flag is changed, the filename changes so it's now stored twice in the backup server. So when restoring mails, be sure not to restore duplicates.
Using a different dedicated directory for restored messages could lead to the same problem?
If you didn't give --delete parameter to rsync, there could be duplicates, yes. Dovecot just logs about them and gives new UIDs to them, so you'll end up having duplicate mails. I suppose some day I should just change it to log a warning, but delete if the files are otherwise identical.
Using rsync will have the flags issue and others to be dealt with; lvm (or any other kind) of snapshot and rdiff-backup gives you a consistent snapshot, as well as the option of saving a lot of space and time as only changes gets backed up. As a bonus you can also restore anything to a given point in time, either induvidual messages or whole folders or even the whole mailbox.
