Help understanding the background retention task

[kevin.boddy]

Hi,

I have a forever forward incremental backup with a 30 day retention. The VMs in the backup job are removed and the backup job is left to run on it's daily schedule.
The background retention then deletes the old backup files as they fall out of the retention policy, finally deleting the .vbk and then removing the backup job from the configuration.
The backup job then fails with an invalid parent backup failure message.

Is that how it is supposed to work?

Thanks
Kevin

Hi Kevin

then removing the backup job from the configuration.

The background retention job does not delete backup jobs from the configuration.

The backup job then fails with an invalid parent backup failure message.
Is that how it is supposed to work?

Getting an error message always means something unexpected has happened. I recommend to contact our customer support team. We need your log files to investigate this issue.

Thank you,
Fabian

Hi Fabian,

What is supposed to happen then with the background retention task?
You said this is unexpected. What should be expected when it deletes all the remaining backup files?

Thanks

Hello Kevin,

Background retention cannot delete the entire chain from backup job, as well as it does not delete the backup job. The main goal of this feature is to remove the 'orphaned' backups which were detached from the job and sitting in the B&R as Orphaned backups.

The VMs in the backup job are removed and the backup job is left to run on it's daily schedule

Please check if Retention Policy for Deleted Items option is configured, this one can delete the data for the VM source, that has been removed from the job. However it cannot delete the entire job from B&R, only the backup of the machine.

Hi,

Yes we also have a retention policy for deleted items of 30 days and the backup job is set with a retention policy of 30 days.

What is deleting the backup files, causing the invalid parent backup failure message and then removing the backup job from VBR?

There is nothing left on the backup repository except the .vbm file.

Is this the expected behavior or not?
