Problem with full PSA backup restore

[calderwood]

I upgraded to 8.4, the server failed, so I re-formated server and re-installed a fresh OS with PSA 8.3 the did a full restore using the most recent backup. Do I need to update to 8.4 again before restoring as I got these errors:

WARNING: Backup file has wrong signature for this server

WARNING! Restore with "-level server" switch brings server to exactly the same
state, as was saved in backup file. All objects, not presented in the backup
file (clients or domains) will be deleted. Proceed? [yes/no]: yes

Hello!

Looks like the backup was made by Plesk 8.4.

Thanks.

Upgrade

Yes I did in fact have to update the system to 8.4 before restoring the files. Of the backups from the last three days, the most recent 8.4 backup was in fact corrupt and the only one that worked was an older 8.3 backup. So whatever happened to the system after updating was captured in the backup files. All seems to be running ok now.
