12.1 Linux Agent Jobs Failing - nosnap agents are supported only as members of pre-installed agents protection groups

[JGM2023]

We upgraded to 12.1 yesterday, we are now receiving the following errors on our Linux Agent Jobs (We use the Nosnap package)

Unable to process HOSTNAME: nosnap agents are supported only as members of pre-installed agents protection groups - Our jobs are setup as "Linux Agent Backups", They worked In version 12 absolutely fine.

Has anyone else experienced this problem when upgrading? There Is nothing In the known Issues or upgrade checklist as far as I can see? We have logged a support ticket but thought I would raise awareness here too.

We have been told by support that It shows this In Help centre under Protection groups, but my reaction Is still the same, Why Isn't this In a compatibility check? We can't be expected to check every single help centre article before upgrading to ensure nothing has changed. Have requested a conversion method for these Jobs as we can't run active full backups for over 500 machines.

Agent Version (Multiple versions, All are failing with same error In VBR) - 6.1.0.1498 / 5.0.2.4606 / 6.0.3.1221

Hello,

Thanks Jacob for details and one more thing.
And those Linux machines all had and have pre-installed no-snap agent, correct?

Rovshan.

[JGM2023]

Yes that Is correct. Thanks!

sounds quite like my problem described in Case-Nr.07065405 - opened Dec 23, 2023. Unfortunately no progress at all until today.
Good luck to us....

Hello,
just to finish the topic for future readers: there is a registry key to bring back the old functionality as experimental feature (as it was before). Please contact support if needed.

Best regards,
Hannes

NOTE:

The above-mentioned key enables the functionality that remains an experimental feature. Use this workaround at your own risk.

Thanks

@HannesK

Is there any chance you could send through the key in order for my backups to get up and running? I have just carried out upgrade and unable to backup atm, I have asked support and they want to go through troubleshooting whereas I just want to get back to backing up for now....
