Okay, we figured out the problem here. The level zero ndmpcopy should have created the "restore_symboltable" file, but it won't do this unless the "-level 0" argument is explicitly called. Now incremental ndmpcopy's work fine.
This behavior is probably reduce the number of stale "restore_symboltable" files laying around that could corrupt future incremental restores, but it would be nice if the ndmpcopy man page described this particular detail.

From Jeff Krueger on Mon, 13 Dec 1999 14:08:46 PST:
I'm trying to migrate a 100GB qtree between two filers using NDMPcopy. A full copy worked flawlessly, but I can't seem to get an incremental to work. The restore process keeps complaining that the "restore_symboltable" file doesn't exist, but restore should be creating that file, right?
Here's a log of the error:

Both crockpot2 and icemaker are F630 heads fully configured with RAM/NVRAM and both running DOT 5.2.3D1.
Any ideas, experiences?
