Multiple sessions with Veeam Backup

If you had to deal with several admins using Veeam Backup 5 at the same time, you may had issues with multiple sessions support.

It’s not possible with an out-of-box Veeam Backup to launch more than one console at a time, so it’s no use with Terminal Services and if you are more than one working on backup, let’s rotate! However, it’s not a technical limit but a support question from Veeam.

Diging into Veeam forum, we found a Gostev post (well known member and Product Manager) explaining :

! this functionality is not fully tested or officially supported (works fine though, according to feedback). We would also like to track customers receiving and applying this workaround !

After a little chat with Veeam support (btw we wanted to thank them for their accuracy and their sympathy), we had the agreement to publish a blogpost with the RegistryHack in order to enable this feature, and allow multiple session support.

Here is the hack :

Browse the registry hive to HKEY_LOCAL_MACHINE\SOFTWARE\VeeaM\Veeam Backup and Replication

Create a REG_DWORD key named MultiSessionMode

Set the value to 1 (multiple sessions enabled) or **** (multiple sessions disabled)

Restart the Veeam Backup Server service

One this tips set, you’ll be able to run multiple session with Veeam Backup console, Welcome in Multi-user mode !

Note : This tips is only applicable for Veeam Backup 5.x, the version 6 of Veeam (which just came out) works fine with multi-session out of box :p
