We have a problem with backup and only backup on a CSV storage Windows 2012R2 up to date with last KB.
On backup with Veeam we have high latency up to 5 seconds and sometimes 15 seconds !
Perfmon show latency only on IO Redirect. So it seems there is no problem with storage.
And IO redirect show high latency also with only one node !
I dont understand why there is IO Redirect when we have only one node UP. Why CSV dont make direct IO ?
Do you know issue ?
Thank a lot
