The storage shows less than near zero busy time on the RAID. The backup storage shows less than 1Mb of activity over the 10Gb link. The backup storage isn't getting taxed, either. The VM OSes (Windows 2008r2) report less than 20% (dual) CPU usage, less than 10% disk busy time, and less than 10% (~100Mb) network usage. In fact, there's more than enough performance to spare. I can run 10 VM backups simultaneously and not impact the performance of the VMs' services at all. I've tried both direct VM backups without GRT, VM backups with GRT, and agent backups from the VM OS. Even the previously fast backups have slowed to the same crawl. It is taking upwards of 5 days to complete the jobs. For the VMs, though, I'm getting 180-240MB/min for all the backups, including our big file servers. The physical machines backup slowly, at about 600-700MB/min, but they aren't horrible. Upon moving the rest of the servers (VMs and physical) over to the new backup system, it slowed down horribly. It's tested and ready to take on the rest of the backups. The actual backups, 3 VMs and one physical machine, are showing 1300-1700MB/min speeds in Backup Exec.
The first 4 backups I put on there worked perfectly, and I was seeing 1.3-1.8 Gb traffic on the server network side and 400-700Mb/s traffic on the iSCSI side.
I start out with the new backup system, the exact same server and storage, but with 10Gb networking using an Intel dual port X520 and Cisco Nexus switches, one link for network and the other for iSCSI traffic. Mostly, backups would average 500-600MB/min. It was able to back up even our largest file shares in just over 28 hours, so all the full backups could get done over a weekend. The old backup server only had 1Gb networking, and the previous admin had it set up with 2 1Gb links software bonded (Windows 2012r2 link bonding) and the iSCSI storage also used just a 1Gb link. On BE 2014, I managed to adjust things to get the backups stable and performing OK. Not wanting to make waves, I went along with it and tuned up the old 2014 setup, and made the plans to move to the new BE 15 setup.) This decision was made before I joined the company. I was very familiar with it, and hadn't had too many issues with it previously, but I still knew its reputation. I've recently moved our main backup system from Backup Exec 2014 to Backup Exec 15.
