Question

Is it safe to remove mysql.preupgrade.* files from the /var/lib/psa/dumps/ directory, which are created by Plesk automatically?

# ls -lat /var/lib/psa/dumps | grep "mysql.preupgrade"

-rw------- 1 root root 298700 Dec 20 06:20 mysql.preupgrade.apsc.17.8.11-17.8.11.20181220-062042.dump.gz
-rw------- 1 root root 259607 Dec 20 06:20 mysql.preupgrade.17.8.11-17.8.11.20181220-062041.dump.gz
...
-rw------- 1 root root 298800 Dec 10 05:22 mysql.preupgrade.apsc.17.8.11-17.8.11.20181210-052236.dump.gz
-rw------- 1 root root 239266 Dec 10 05:22 mysql.preupgrade.17.8.11-17.8.11.20181210-052235.dump.gz

Answer

The mysql.preupgrade.* files are the backups of the databases that are automatically created before any Plesk upgrade/update.

It is not recommended to remove all mysql.preupgrade.*.dump.gz files, however, it is safe to keep the last backups of each type mysql.preupgrade.apsc and mysql.preupgrade:

# ls -lat /var/lib/psa/dumps | grep "mysql.preupgrade"

and remove old backups.
