Plesk for Linux
Connect to a Plesk server via SSH
Run the following command to validate the backup file structure. Replace backup_info_1809291722.xml with an actual backup XML file name:
Note: The command validates only backup structure.
# plesk bin pleskrestore --check-backup /var/lib/psa/dumps/backup_info_1809291722.xml
If a backup file has been uploaded via FTP, specify the full path to the .xml.tar file:
# plesk bin pleskrestore --check-backup /root/backup_info_1809291722.xml.tar
Plesk for Windows

Note: The command validates only backup structure.
C:> "%plesk_dir%binpleskrestore.exe" --check-backup backup_info_1809291722.xml
Possible results
The backup file is valid.
The backup is valid for restoration.
The specified backup file is corrupted, modified, created on another server or in an earlier Plesk version. To restore it, use the -ignore-sign option.
In case the backup was created on another Plesk server, restore it according to this KB article.
