I realise there’s one topic from a couple years back which is close to this, but so far the potential fixes there didn’t apply or help.

I’ve had a backup task now for around a year, 2x SSDs (1x500GB, 1x1TB) from a windows machine. At some point in the past month just after a client update, the read speed of the C drive has slowed down to ~8MB/s from a previous read speed of 150MB/s+. 

The disk is at under 50% capacity, and from Task Manager CPU is at ~25%, RAM (32GB) is at 60%, the disk fluctuates between 0% and 20% utilization, with the disk transfer rate at 0, peaking at about 125MB/s once every 12 seconds.

The disk is about 4 years old, so not new, but also doesn’t show any issues, `winsat disk` shows the below:

This is puzzling me, so any advice would be great. 

What version of Veeam are you using?  Is are you using the Agent if so what version and what is the target for the backup?  If you are using VBR to manage the agent what version are you using?

What is the target for the repository and how is it connected to the systems?  What is your network speeds - 1GB, 10GB, etc.?

We need a lot more details in order to try and guide you but if this is a real problem then contacting support to open a ticket would be the better route to take.  First send us the details and we will try to help out.

Thanks for the reply.

Veeam Agent for windows v6.2.0.121 which I believe is latest, not using VBR. 

Target repository is an SMB share on the NAS, network speed is 1GB. Is the ‘Read’ in the Veeam console also actually a write to the target? That wasn’t clear to me, otherwise I’d have tried something like an iperf between client and target, which actually turns out to be the problem. Le sigh. 

 

 

We can close this, looks like it’s a network issue I didn’t realise I had.

Not a problem glad to hear you figured out the issue and it was network related.  Typically that is the case many times with slow speeds as I just had my backup run and it was 750MB/s+ speeds on my OS SSD and 1GB/s on my Data SSD drive.  But I am sending to a Veeam Repository on VBR versus a NAS SMB share.
