Hi Jeremy,
I think you must have run the engine-setup before the
restore, the restore is designed to restore to a clean install or the previous
install with the same credentials. If you delete the postgresql config you can
then install with your postgres credentials.
e.g.
systemctl stop rh-postgresql10-postgresql.service
rm -rf /var/opt/rh/rh-postgresql10/lib/pgsql/data/*
regards,
Paul S.

I did get a little further.
First I ran engine-cleanup on my new engine where I will be running the restore
operation. (I had previously run the engine-setup script on this machine)
Then I ran this-
[root@engine ~]# engine-backup --mode=restore
--file=ovirt-engine-backup-20200217125040.backup
--log=ovirt-engine-backup-20200217125040.log --provision-db --provision-dwh-db
--restore-permissions
Start of engine-backup with mode 'restore'
scope: all
archive file: ovirt-engine-backup-20200217125040.backup
log file: ovirt-engine-backup-20200217125040.log
Preparing to restore:
- Unpacking file 'ovirt-engine-backup-20200217125040.backup'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
FATAL: Existing database 'engine' or user 'engine' found and temporary ones
created - Please clean up everything and try again
Time to research further for that FATAL error message. Isn't that the purpose
of engine-cleanup though? Why the conflict?

Try looking at the RHEV info here and go to section 6.2.2 and see if that helps.

OK, I was able to get the backup completed. I am a little confused on how to
do the restore though.
https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environment.html<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt.org%2Fdocumentation%2Fself-hosted%2Fchap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environment.html&data=02%7C01%7Cp.staniforth%40leedsbeckett.ac.uk%7Ccd79555b8ae944903bfb08d7b439437e%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637176030350726202&sdata=m7M4G8R74x21WFDKT%2BGaKISRX01Ua9A749vsQRVROw4%3D&reserved=0>
Is this link even applicable? My environment is a single node, not EL based.
Anyhow, here is what I have so far-
[root@engine glusterfs]# engine-backup
Start of engine-backup with mode 'backup'
scope: all
archive file:
/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup
log file: /var/log/ovirt-engine-backup/ovirt-engine-backup-20200217125040.log
Backing up:
Notifying engine
- Files
- Engine database 'engine'
- DWH database 'ovirt_engine_history'
Packing into file
'/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup'
Notifying engine
Done.
[root@engine glusterfs]#
I moved the backup file to my new engine.
How do I perform the restore?
The directions say:
# engine-backup --mode=restore --file=file_name --log=log_file_name
--provision-db --provision-dwh-db --restore-permissions
What is the file name and log_file name? Do I need to do something to unpack
my backup file?

Can you take a backup of the original, build the new one, then do a restore?
