Backup is slow while taking from Netapp Cifs filer to DSU on SAN
I have Netbackup 7.5.6 master server on windows 2003 R2 Enterprsie Edition. we have a Netapp FAS2240-2 CIFS Filer.
I have create a policy to take backup of my CIFS filer (file server) actually current size of filer is appx 410 GB.
We have created a DSU's on Netapp SAN for primary copy, then secondary copy will be copied to TAPE using stagging.
when i take backup from netapp cifs filer to DSU, it took too much time , around 12-13 hours for full backup.
I want to know is any guidence or suggestion to improve the speed to minizime the backup windows time.
While from SAN to TAPE it took 4 hours.
