Re: [CentOS] Backup solution to backup /var/spool/imap above 150GB data

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
