Issue Restore Incremental Backup

[GuillaumeM]

Hello

My dedicated server has burned (OVH SGB2 incident).
I ordered a new one.

Both have Plesk Obsidian 18

I use Plesk Backup manager with OVH's Storage Backup in Incremental mode.

My last full backup was on 2020-11-11.

I successfully restored this one.

But I can't restore any incremental backup (the last one is on 2021-03-09 so it can be perfect).

When I click on a incremental backup I have this error :

Error: Failed to open the dump backup_**************.com_2103090708.tar: Import error: Unable to find archive metadata. The archive is not valid Plesk backup or has been created in an unsupported Plesk version

How can I restore my last versions of my backup (this one) ??

Kind regards everybody

Guillaume
