We are changing storage providers soon (Compellent), and in the meantime need to run our backups on-host. I'm just wondering how much influence the CPU/Memory on each host, has towards prcessing backups ?. Or is the speed of a backup (among other things such as compression etc) mostly relying on the speed at which each host can read from the SAN/CSV ? Any tips to increase on-host backup speed, would be appreciated!
At the moment, I'm using the MS VSS provider, Optimal compression and LAN target (as backups go onto local disks on another server).
