The only time I've used the Upgrade Data or the console data was for an
upgrade, and twice (since the HMC came out with P5) to repair an HMC that
had a massive hardware failure. I do them and keep them off site more for
the auditors piece of mind than my own. Particularly since you can recover
the partition information etc. from the ASMI on the POWER system if it comes
to that. I've never restored a single file, even at IBM's prompting.

Subject: vHMC backups
Summary question: Do you ever restore single files back to your HMC or just
full system restores? If I never restore an individual file then it has a
significant impact on backup.
I don't recall ever having done either. Normally I do a vHMC snapshot and
the "Save Upgrade Data" and "Backup Management Console Data" right before an
upgrade. I don't recall ever having ran "Restore Management Console Data"
Currently we backup our vHMCs with Simplivity backups and IBM Spectrum
The Simplivity backup is good for a full system restore. The IBM Spectrum
Protect is better suited to restore individual files, along with full system
Both do the offsite replication, etc
It is suspected that the way the IBM Spectrum Protect is configured to do
the backup it causes some brief disruption between the HMC and the Power
Systems. It's not that critical. You may lose system console sessions but
if you've configured "console takeover" it is not disruptive to that job.
It's normally at o'dark thirty too so not so noticeable other than you have
to reenter the shared console session password at the HMC. However if this
backup is unnecessary it would be nice.
