Slow first backup of new machine (source 99%)

Post by B_J »

Hello.
Added a new VM today and thought i run a first backup job on it.

To my surprise it's running incredible slow, i'm seeing speed of 14 MB/s where as my backup of last night of another VM on the same SAN partition ran with ~440 MB/s
I have ran the "rescan storage" under backup infrastructure and checked the logs, it doesn't fail over to network mode, and even if it did i would have higher speeds than this.

Source is reported as bottleneck.

I'm running v6.

Any ideas?

Regards
Björn

Hi, what do the 4 bottleneck numbers say in the real-time statistics for this VM?

Source 99%
Proxy 53%
Network 0%
Target 9%

A quick edit to this:
These are the figures i have on my other jobs as well.

What was the speed of your initial runs of other VMs? Comparing the speed of an initial full to the speed of an incremental will always show extremely different results( i.e the 440MB you are getting on an incremental)

It really shouldn't, are you using VSS(Guest aware image processing) on this machine that you are not doing on others?

Yes, the issue is clearly the source data retrieval speed. Something is wrong with the storage or connection to it. You should troubleshoot your storage infrastructure.

It's hard to say anything without seeing your bottleneck stats and additional info about the setup.

Hi Vitaliy,

The backup used 3 hrs everyday, our Veeam is installed on Windows XP x64 with icore 3 CPU and 4GB Ram. But other VM around 50GB - 200GB only used 3-6mins.

Thanks

What is the bottleneck statistics (4 percent busy numbers) for the problematic VM?

It's on the job's shortcut menu > Realtime Statistics > select VM in question.
