Hi,
Our legacy data store retains a single copy of a message regardless of the number of mailboxes in which that message resides. It does this by creating hard links to that message in the mailboxes containing that message. Thus, when we perform data migration to the server target (Dovecot), the copies of the same message are copied over with the migration process (imapsync). We use the storage format maildir. With a small message store, this means that a lot of messages are duplicated unnecessarily. How to reduce message store size due to duplicate storage of identical messages ?
Does a relinking function exist and can be run in real-time mode ? how can we configure Dovecot to deduplicate for all users using a hash to determine whether the file could be already exist ?
Thanks in advance.
