VMware backup speeds SAN
I've added a large VM estate to my backup enviornment. I am on NetBackup 18.104.22.168 and backing up my VM's across the SAN. I am backing up 5 at a time at the moment, and using a query based client selection. I backing up 1 ESXi host at a time, but for the active jobs i am seeing around 12mb/s each, totalling a max of 60mb/s for 5 combined jobs.
I've seen this tech note however i dont think this is the case as my SAN backups are not that slow, however across the Network they are just as fast.
My policy is set to SAN, yet the job detailed status is showing the transfer type as black, yet when the job is finished it shows LAN. But whilst the backup job is running the NIC on the VM backup host are not utilisted.
Anyone have any performance improvement idea's for VM's?
