Busy adding another proxy to see if it helps.
Running VMware 6.5, and all proxies are VM's using hotadd.
We though don't have many VM's with many disks, but have some large jobs.
Just did an inventory of our VM's in on of our vCenters. Out of around 400-500 VM's,
only 9 VM's has over 3 disks (Ranges between 4-7 disks)
Around 70-75% of the VM's has 1 disk, and 20-25% has 2 disks, rest is above.
Can you look at your jobs and see where the slowdown is to maybe shed some commonalities with our setup? When we look at our jobs, we can easily see the issue. All VMs process correctly (with low incremental backup times 5-10 minutes) until they hit those two "bad" VMs. Then the backup time for those VMs and any other VMs processing at the same time blows up to 2-4 hours. After those two VMs are processed, all remaining VMs are processed correctly again (5-10 minutes). You can literally see it in the backup summary report without even digging deeper. The "duration" column will be good, good, good, bad, bad, bad, then good , good again as soon as the "bad" VMs are done processing (good VMs are also affected while the "bad" VMs are processing concurrently, but everything goes back to normal as soon as the bad VMs are done). This customer only has two VMs with high disk counts out of 60 VMs, but those two are causing a real headache. Hopefully, when you find which VMs are causing an issue, you can share specs on them.
