Replication - Applying retention policy

Veeam Logoby obroni » Wed Jan 25, 2017 1:19 pm

Hi All,

Does anybody know if there is a registry key which controls how many concurrent snapshot remove operations can be carried out when Veeam is removing retention points at the end of the job? It seems that it will only issue 4 at a time currently and I would like to be able to increase this.

Hi Nick, you're correct, the number of concurrently removed snapshots is limited by 2 per single host and 4 in total for the entire cluster. Both numbers are configurable with the help of the MaxConcurrentDeletingSnapshotsForHost and
MaxConcurrentDeletingSnapshotsForCluster registry values (DWORD).

Awesome, thanks for that. I was checking this KB

https://www.veeam.com/kb2182

Not sure if they are worth including in there?

I believe the article contains just the most commonly used values, while these two are definitely not.

[MERGED] How to set the max number of "applying restore poin

Veeam Logoby marieelieg » Fri Nov 03, 2017 7:48 am

Hello dears,

I have a replication job that contains 7 VMs. At the end of the job run we have a phase called "Applying restore point for VM <vm name>" for all the VMs. Right now, this phase works for 4 VMs in parallel, and when 1 of them finishes the 5th VM starts and so on. My question is: How/Where can I specify the max number for this? I want to be able to start this phase for all 7 VMs in the replication job at the same time.

Hope my explanations were clear and thank you in advance for your help!

Have a nice day :D

Hello guys,

Where can I change these values? On the Hyper-V hosts themselves? the Veeam Backup Server? and what is the path for these values in regedit?

Thank you so much and have a nice day!

You should create them in the standard Veeam registry hive on the backup server (HKLM\SOFTWARE\Veeam\Veeam Backup and Replication).
