I understand that COW file-systems can do snapshots at “instantaneous” points in time and KVM snapshots ram state as well, but I still worry that a database could be backed up at just the wrong time and be in an inconsistent state at restore. I’d rather do less frequent backups of a stopped VM and be more confident it will restore and boot correctly. Maybe I’m a curmudgeon?

I suppose it boils down to a threat model. I wouldn’t lose sleep if any of my VMs imploded and I had to rebuild them from scratch.
