OK, the restore had took complete 5h 15min which is quite a bit longer that the backup. Good things, all partitions are there and boot from the restored System HDD (which I had formatted upfront) were just fine. That said, unlike the version 9.x the version 8 of this Acronis Echo Enterprise Server is working correctly. Tomorrow I'll carry on to check with CloneZilla again. That last I'd done were not able to restore! More to come will be PC-Backup, Amanda, FWBackup and Idera Backup Server. Again, all will be done for Linux Debian Server only and NOT any version of MS OS's!
