I'd like to see if anyone out there could provide some clarification on something.
I have a client with a FAS2040 with several volumes that are assigned to an ESXi cluster via NFS. They are using SMVI for local backup but they have the need to write to tape for off site disaster recovery. We are going to use the enhanced NDMP option through Backup Exec 2010. My question is as follows:
1.) In this model, is it possible to do an incremental backup of these volumes using NDMP?
My plan is to write a level 0 backup on the weekend and then do level 1 backups during the week.
I'm a little confused because I was under the understanding that NDMP is a block level copy but the documentation refers to the incremental determination based on "file dates". In a block level copy, Backup Exec shouldn't really know anything about files. How could it do a block level incremental? I'm assuming that Backup Exec is talking to the Netapp and saying, I backed up from Snapshot A on Sunday, I need all of the changes from that snapshot up until now.
I want to make sure it's truly an incremental and the combination of Backup Exec and Netapp is smart enough to truly do a NDMP block level incremental backup.
Thanks in advance for any replies.
