  Alternatively, you can use NDMPcopy available on

This is the approach we've used successfully many times. It's nice to do a level 0, then do a 1, cut to the new filer, then do a level 2. If you plan to do the whole thing at during hours of light load, the risk involved here is negligible

We've used NDMPcopy to do just that, and it works pretty well. In one of our more recent adventures with NDMPcopy, however, the level0 of a ~100GB directory worked, but the level 1 bombed out with a "volume too high" error. That was really irritating, espescially when NDMPcopy usually works. We resorted to a date-restricted GNU tar to capture the very rough equivalent of a level 1 dump.
