Question mysql daily dump task

[Sellighsphire]

Hello!

I 'm facing some quota issues.
I created a daily full backup to my external ftp-server (rotating 14 days). This works fine.
After all, plesk creates a mysql daily backup in folder /var/lib/psa/dumps which aren't deleted at any time.
Therefore my quote drops and my daily backup fails because of the lack of disk space.
Is there any option to
- disable daily mysql backup of plesk
or
- reduce number of daily backups created by plesk?

Is there any option to automatically delete the preupgrade dumps after sucessful update?

Regards
Jens

P.S.
Plesk Onyx - Version 17.8.11 Update #89
