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

[aleksey.maksimov at it-kb.ru]

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-restore/

And at the same time, in another document, there are no such steps:
https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/single/self-hosted-engine-guide/#sect-Restoring_SHE_bkup

What should be the correct procedure for the recovery of Hosted Engine 4.0 ?
