The only sure strategy is to do your dumps in single user mode, with

This obviously won't fly in a 24x7 environment, so people take their
calculated chances and run backups with the system live.
That's what snapshots are for.
No need for single user mode or taking chances.
A snapshot gives you a consistent filesystem that you can dump or tar.
