Plesk Administrator receives an email after creating a scheduled backup to OneDrive or other remote storage:
CONFIG_TEXT: pmm-ras failed (Error code = 1): Repository error: Failed to read backup backup_1912140200_1912180201.zip: Import error: Unable to find archive metadata. The archive is not valid Plesk backup or has been created in an unsupported Plesk version
Note: The mentioned file is not the newly created backup but an old one.
Similar error can be found in an attempt to remove the backup file from the error directly via the Plesk interface in Tools & Settings > Backup Manager.
Corrupted backup file in the storage.
Remove the file
backup_1912140200_1912180201.zip mentioned in the error and other
backup_1912140200*.zip files directly from the remote storage via its interface.
It may additionally be required to find mentioned backup timestamps (in this case
1912180201) in the
/var/lib/psa/dumps/.last-dumps file and remove these lines from the file.
