OSVDC Series: oVirt Hosted Engine Backup - rharmonson/richtech GitHub Wiki
For convenience, I have created this page to link back to the oVirt backup procedure.
https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.html
Example:
Log on to the engine and execute
[root@engine ~]# engine-backup --mode=backup --scope=all --file=engine2019feb20.tar.bz2 --log=engine2019feb20.log
Copy the files to a safe location.
