Plesk 12.5 incremental backup takes +10GB everytime

[Xav2c]

Hi,

My daily backup weights 18GB and i was really counting on this new incremental backup system, but even if there is no addition to any object in production (except for mails), the incremental backup weights 10GB!

What is the reason of this?

In a day there has been a maximum of 200MB new mail data, but no more.

Maybe you have 10GB database? Incremental backup increments only vhosts and, probably, mail.

Hey! thanks for your answer.

Total database disk usage = 1 922 980 155 bytes or 1,79 GB

I finaly found the time to investigate into this further, every incremental backup, the whole mail accounts are backed up, again, not just the few new mails as an increment.
Since most of our data volume is inside mailboxes, this incremental system is almost useless.

I was really counting on a true incremental backup, not just a system which backs everything up as long as a tiny bit has changed.
