Veeam VM Backup software restore agent timeout fix.

Veeam Backup and Replication software is a very popular Virtual Machine backup software at the moment. It is very robust and offers a lot of options for backing up and moving your virtual infrastructure off site.

Recently after setting up the software I discovered that after about 11 hours of a restoration processing of a 4TB MSSQL vm backup the software would hang and the restore would fail.

After about 3 weeks of back and forth with Veeam support and digging into the software my entire infrastructure and even my SAN. The developers came back with a registry entry fix that prevents the software from hanging on restore. This registry needs to be added to the Veeam Server,  Veeam Proxies, and Veeam Repositories.

Essentially you need to add this to any and all installations of Veeam in your infrastructure. Then all you do is Restart the Veeam Transport Service, named Veeam Data Mover Service. Alternatively reboot any and all servers.

The registry entry you need to add is as follows;

name: HangedAgentKillTimeout
path: HKLM\SOFTWARE\Veeam\Veeam Backup Transport
type: REG_DWORD
value: 28800

You can also put the following in a batch file if you’d like.

Reg Add “HKLM\SOFTWARE\Veeam\Veeam Backup Transport” /v HangedAgentKillTimeout /t REG_DWORD /d 28800

  1. Hello Dave, before I go over to learn more about crossovers I have to tell you how much I have thoroughly enjoyed the time I’ve spent on your site reading your articles. I started a few hours ago at Monoprice looking at Logitech remotes. Then, looking for more information came across one of your articles that looks like it was written in 2016? Wow, how much information you put down and so in-depth, with so much detail. From there I followed one link to another until I ended up in the basement of your new house. I really thoroughly enjoyed the time I spent all the way to learning about your new system and how you got there. BTW, belated congrats on the new home purchase. Regarding Home Theater, I have much interest as I’m currently upgrading my home theater components. I only just found Monoprice a few months ago. What a great find. Are you familiar with Fluance? They’re a Canadian Speaker Company. I’ve been trying out their 12 in subwoofer (DB12) but I think it’s going to go back as I have figured out a way to spend more money on a subwoofer. But I’m probably wasting money as this really is a very nice subwoofer I already have here. Anyway, I didn’t want you to talk about my system I want to acknowledge all the time you have put forth to help anyone seeking information and how much better off they will be if they find your site. It seems you have the unique ability to better explain what many find to be difficult or perhaps dry technical jargon. Thanks again. Regards… -joe
