[ovirt-users] Correct recovery procedure of the oVirt Hosted Engine 4.0

Hello oVirt guru`s! My Hosted Engine VM located on a dedicated LUN FC Storage. I do daily data backups (on NFS share) with the command: /usr/bin/engine-backup --mode=backup --scope=all --file=$BcpFileName.xz --log=$BcpFileName.log --archive-compressor=xz --files-compressor=None However, I don't know what would be the correct procedure to recover, because in different manuals outline the various steps. For example, there is information that I have to do configure postgresql (with password from file files/etc/ovirt-engine/engine.conf.d/10-setup-database.conf) before restoring (engine-backup --mode=restore): https://www.ovirt.org/documentation/admin-guide/hosted-engine-backup-and-... And at the same time, in another document, there are no such steps: https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/sin... What should be the correct procedure for the recovery of Hosted Engine 4.0 ?
