I'm backing up my primary Netapp filer using NDMP to a tape library. I have Daily backups configured during the week and full Weekly backups over the weekend. Everything was working well until I setup a SNAPMIRROR relationship from a Branch office to this site. The data being mirrored over is about 3TB and when included in the selection list is being backed up as if it was a full backup during a daily backup job. I suspect this is due to the fact the archive BIT is not being reset at the source and snap mirror is a readonly copy.
I see some people talking about different netapp NDMP level options. Do I need to set up different jobs from the rest of my CIFS backups to deal with this SNAPMirror data? Can someone who has done this before provide me some direction.
Thanks
