Everyone knows that.
Which is why I have replication every 5 minutes, absolutely foolproof.

True but a ZFS snapshot almost is.
No, but it's a backup to the backup, so that if my changes go poorly, I can revert to a previous state without needing to restore a whole-ass backup
They're incremental backups.
100% always take a snapshot before 3rd party app upgrades if you can. Now... remembering to cleanup the snapshots is another story
Explain
You should do real backups, that won't get corrupted by the same changes that corrupts your main system.
If you have some external dependency that takes your VM down, the image will be down too.
What? If your hypervisor shits the bed, you have bigger problems.
You should have multiple backups, at least one which is on a different medium/different location. Its absolutely fine to have a backup on the same machine, even the same hard drive as the working copy. As long as it is not the only one.
VM snapshots are a backup! Change my mind!
Not until you print it out
You misspelled "screenshot" btw
So what's your back out plan?
Woodworking. Farming, maybe.
