we have installed VBR on a physical server, that is...
backed-up with Veeam Agent for Windows ( just for sake of the Operating system and C drive based on volume level backup ).
We copy this backup to another server with a backup copy job.
We experienced a hugo performance impact when we have had installed the agent on the VBR server during backup copy jobs / backup jobs.
After uninstalling the agent, all jobs where running properly again.
hmm, I checked the case and it looks like it's about agent speed in general. I remember that I answered to you some days ago file level backup vs. block level backup in another thread.
If you really want to dig into that, then I would recommend the following
- fix all open issues / cases
- reproduce the issue again and open a new case (no need to post it on the forums. it's not a "general known issue" and it does not help if everybody posts his cases on the forums)
mixing different issues into one case rarely leads to good results...
