Question about how backups should be configured
I have a question about how I should configure our backups and i'm hoping someone here can answer my question.
Just so you are aware of the setup, we have a Netapp FAS3040 connected directly to a tape drive via fiber. We have the NDMP license and backup serveral volumes from the Netapp to tape via NDMP on a weekly schedule. We also have several B2D volumes on the same Netapp device, and I need to be able to duplicate the data on these B2D volumes to tape.
Sounds easy enough, but if I configure the standard option of "Backup to Disk then Duplicate to Tape", when it tries to write to tape I get an overwhelming speed of 14mb/min. I'm not really sure why it's THAT slow, maybe someone could offer some insight as to why.
But my main question is whether I can configure it slightly differently, so that I still have my Backup to Disk jobs, and then when I run the NDMP job at the weekend, I can just include those B2D volumes and back them up that way. This would give me my normal 4500mb/min backup speed, but would this provide a valid restore path? In the event of a restore I guess I would need to restore the data back from tape back to the Netapp, and then catalog those B2D files, and restore the actual data from them?
