Azure Stack HCI - performance degradation over time
Hi Karl-WE,
Lets first be clear where you see the degradation, is this inside the VM or do you see latency counters go up on the physical disk side?
There is a long standing and known issue when using CBT and particular backup software. A live migration of the virtual machine typically solves the issue. This issue is caused inside the VM, you won't see any latency or errors on physical disk level.

Dear Darryl van der Peijl thank you for taking the time to reply.
Quite unfortunately the customer in question didn't provide any further detail, as they agreed to do so.
Could you name some solutions causing this like CommVault, Veeam B&R or Macrium Reflect ? Are they all affected? So as a remedediation live migrate the VM after the backup with a post backup task or disabling CBT?
DanCuomo cheers, I will do so once I receive more information on the matter.
