Resolved Backup fails, Unable to create dump, Debian 9.6

[OldShadowHand]

I just updated my "Debian Version" to 9.6 (with the plesk update manual) and now my Backups aren´t working.
Plesk version: Version 17.8.11 Update #35

I tryed Full and Incremental Backup, each one ends with this error:

DEBUG Unable to create dump: Can't locate object method "getDumpFilesSize" via package "Storage::ArchiveStorage" at /opt/psa/PMM/agents/PleskX/PleskX.pm line 5211.

Try to fix it with

# plesk installer --select-release-current --reinstall-patch --upgrade-installed-components
# plesk repair installation
