Veeam Backup Server, Proxy, and Repository are all on the same server.
I am trying to determine how to solve a performance problem with my backup jobs. Target is being shown as the bottleneck, with % busy usually around:
Source - 10%
Proxy - 1%
Network - 40%
Target - 75%
Backup is running over FC SAN.
Target repo storage is 4x 7.2k RPM SAS drives in RAID 5. They're local disks on the Veeam server.
I'm considering doubling the number of drives in the array to 8 (or even tripling it to 12), and making it RAID 10 instead of 5. Theoretically (based on this calculator http://wintelguy.com/raidperf.pl) I think I should see a 333% increase in IOPS by switching to an 8 disk RAID 10, or 500% increase in IOPS using a 12 disk RAID 10. Should I expect that to have a real-world performance increase in 333 or 500 % on the MB/s processing rate of my backup job?
Some example statistics from a recent job are pasted below:
