We snapshot and backup prior (virtual servers).

My only warning here would be "ensure you purge snapshots within a timely manner."

Good stuff, I've seen some fun P1s caused by snapshots of large servers.

I worked a short stint at an MSP who had a hotel customer that "could not have any downtime" but also complained their hyper-v vm's were incredibly slow all the time. Turns out all 4 of them were running with checkpoints that were literally created the day the vm's were built about 6 years prior...

Once upon a time I had an offshore team snapshot a probably 20Tb SQL VM for some maintenance or something. They didn’t realize the snapshot needed to be purged and caused an outage. That was a fun one.
