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:
% ndmpcopy crockpot2:/vr_data icemaker:/vr_data -level 5 Connecting to crockpot2. Connecting to icemaker. crockpot2: CONNECT: Connection established. icemaker: CONNECT: Connection established. crockpot2: LOG: DUMP: crockpot2: LOG: creating "/vol/vol0/../snapshot_for_backup.4609" snapshot. crockpot2: LOG: DUMP: crockpot2: LOG: Using Partial Volume Dump crockpot2: LOG: DUMP: crockpot2: LOG: Date of this level 5 dump: Mon Dec 13 11:18:37 1999. crockpot2: LOG: DUMP: crockpot2: LOG: Date of last level 0 dump: Fri Dec 10 11:30:55 1999. crockpot2: LOG: DUMP: crockpot2: LOG: Dumping /vol/vol0/vr_data/ to NDMP connection crockpot2: LOG: DUMP: crockpot2: LOG: mapping (Pass I)[regular files] crockpot2: LOG: DUMP: crockpot2: LOG: mapping (Pass II)[directories] crockpot2: LOG: DUMP: crockpot2: LOG: estimated 378962 tape blocks. crockpot2: LOG: DUMP: crockpot2: LOG: dumping (Pass III) [directories] icemaker: LOG: RESTORE: icemaker: LOG: restore: Cannot open symbol table file /vol/vol0/vr_data/restore_symboltable: No such file or directory icemaker: Connection halted: HALT: Internal error! Elapsed time: 0 hours, 28 minutes, 1 seconds.
Both crockpot2 and icemaker are F630 heads fully configured with RAM/NVRAM and both running DOT 5.2.3D1.
Any ideas, experiences?

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.
