ONTAP: 7.2

NetBackup: 6.x

I'm doing some NDMP full and cumilative incrementals on some NAS data via NetBackup. I've noticed that the incs are taking the same amount of time as the fulls and are backing up roughly the same amount of data. The change rate on the NAS data isn't that great. I'm also doing the NDMP dumps from the SnapMirror destinations.

I was hoping to save some tapes by doing incs over nighlty fulls. Can anyone help please?
