Hi
We have an issue with one of our clients , they have a mail server with the /var/spool/imap partition as 150 GB . They need to take differential backup on to /backup partition ( a different HDD of total 250 GB space )
.
We have tried dar , rsync, rdiff and impasync . But its is not sufficing
the
need as to take a lot of time and consumes a lot of I/O .
Is there any back up solution that you can think of , that can work in
this
situation - open source or proprietary
Is seems to me, that you are using mbox format. So, differential backup is hard to achieve. Migrate to maildir, every mail is a file, easy to backup differentially. David
backup directory structure is /var/spool/imap/a /adomain.com/a/agnello^dsouza/
