<![CDATA[Backup fail Unable to get the true granularity: 60 & worker exited with code null]]>I am getting some strange errors with a backup job which i had running for few months with little issue..

Any ideas what can be the issue.

I am running this xoa with 6 vcpu and 8gb memory.

Some more details about my setup/environment

Details of the Problematic Backup Job

  • Backing up 13 VMS running in in the same server pool as xoa
  • Daily Backup job set for 11:15 PM
  • Retention = 30
  • backup to an NFS Remote

I have other delta backup jobs for other vms in this environment which seem to not fail. I do not think the time has much to do with this issue because it seems to fail if i disable all other backup jobs and keep only this one enabled. I started to get these errors but I don't really know what the error means in this context.

Thanks

You should include additional details about your environment, XOA or XO from sources, release channel / commit, backup job details, etc.
