Yes..netapp NDMP backups use the dump (solaris version of ufsdump)command to 
perform backups. The following link explains the NDMP "dump" process, in detail:

Subject: [Veritas-bu]  NDMP backups from Netapp using Netbackup
Sent: Jul 27, 2010 7:45 AM


One of my customers says that his NDMP incrementals are 3TB in size, while his 
full backup size is 6TB. However, when he checks for the block changes in 
Netapp console,it reports block changes amounting to 60GB

I was of the impression that NDMP incrementals happen at the block level, in 
which case his incremental size had to be around 60GB.

Can someone explain to me why this is so.

Appreciate if you could get down to nuts and bolts and tell me how NDMP treats 
incrementals/level backups.
