I am having problems with backing up a 2 volumes from my HP MSA1000 SAN to an LTO tape library. The volumes are 80 & 90 GB in size and contain around 600,000 small files in each set. The 2 volumes are RAID 5 and I am getting about 5-8 GB per hour back-up. I am also backing up other RAID 5 sets and getting much better performance. I am running Commvault V5.0 and back up through a dedicated Gig LAN. Can anyone offer any advice please?
