Issue Can't restore Backup from Google Drive

[filavision]

I have a Plesk Server with Obsidian 18.0.35 Web Host Edition. I do a scheduled daily backup of the whole Server with 50 Clients and 100 Domains. The Backup file is 65GB. When i try to install the backup on another Server (exactly same machine) it is running since 1 day now without creating any Client or any error message. Tested it on 2 different machines.

Source & Target machine: Ubuntu 20.04.2 LTS

Please help.
