As you did a full backup including the data warehouse you need engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --provision-dwh-db --restore-permissions see https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migratio...

Chapter 12: Backups and Migration Backing Up and Restoring the oVirt Engine Backing up oVirt Engine - Overview. Use the engine-backup tool to take regular backups of the oVirt Engine. The tool backs up the engine database and configuration files into a single file and can be run without interrupting the ovirt-engine service..

Please see '/usr/bin/engine-backup --help'. I'm running ovirt Version:4.3.4.3-1.el7 If I run # engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --no-restore-permissions still the same error Any idea?
