Choose specific backup location for backups during upgrades

I currently backups to:

  • Local
  • SAN
  • Nabu Casa
  • Google Drive

(Overkill I know, but after a about 30 years as an sysadm, I’m paranoid)

I would very much like to choose only local storage and SAN for backup when I do an upgrade. Right now it’s all or nothing.
Reasoning: Backups during an upgrade is for quick rollbacks, and not for disaster recovery.
