sure you have a backup before you use it.". Does that still apply? How
safe is it in practice?

When I used it with 3.1 to backup filesystems overnight, about 25% of the time, there would be a deadlock in the morning required a hard reboot. As this was a mission-critical server I didn't have opportunity to investigate further. I would be interested to know whether 4.0 should be better.
