Easy backups via snapshotting is quick to say, but has an outsized benefit IME. My go-to approach for keeping many of my machines up to date is now scheduled apt get update; apt get upgrade and relying on scheduled backups in the unlikely event that goes awry. I don't have to worry about package interdependencies across machines.

For major upgrades, I may go a step further and do a manual snapshot before upgrading and then decide whether or not to commit (usually) or rollback (easy, when needed).

The (emotional) security provided by this is nice, as is the time-savings (after initial time expense to learn and setup the base proxmox infrastructure).
