VEEAM 12.1 Error: Cannot find parent backup for child

[rpiercey]

Hi Veeam R&D Forum,

I recently upgraded a VEEAM install to V12.1 and ran into an issue that caused me to lose manageability of ~50% of my backups.

Process followed:
• Deployed 12.1 Upgrade
• Upgraded backup chains for all backups.
• Create new Backup Copy Job as required for one set of VMs.
• All Backup and copy jobs ran fine.
• Deployed a new hardened repository for Backup Jobs.
• Moved backup jobs to new repository - validated they all worked after moving.
• Validated backups are listed on new repository in VEEAM.
• Disabled and removed old repository.
• ~ 50 percent of my jobs failed: Error: Cannot find parent backup for child.
• The data for the failed backup job is no longer listed under Backups:Disk so I cannot restore from the files that exist on my repository.
• I also tried to import the backups from the repository and have received the same error.

Opened a Case #07070155

Response “ This is a known issues with how Veeam version 12.1 works with per-vm backups. We currently have two workaround to solve this issue.

1. Rename the metadata file for the job (.vbm) to .vbm_old. Only the extension of the file should be changed, After this is done, you will want to run an active full backup.
2. The other option is to clone the existing backup job and then be sure to not map the backup.”

In my case suggestion “1” didn’t resolve the issue and “2” is basically to re-create all the jobs which is what I wanted to avoid and it leaves the old backups not manageable.

I updated the support case, and the response was “Those are the current work arounds to this issue. I know that our R&D team is currently working on a fix for this issue, but it has not been released yet. If you like, I can put this case on hold until a solution from R&D is provided.”

I have recreated all my backup jobs and will have to manually remove the old backups after they expire.

VEEAM 12.1 Users may want to hold off on moving backups until VEEAM has a fix for this issue.

Can anyone confirm if the fix is incorporated into 12.1.1.56?

[PetrM]

Hi Kevin,

Yes, the fix is included in 12.1.1.56 code but please double-check with your support engineer that your issue matches the one discussed in this topic. The error message itself is quite generic and may occur for various reasons.

Thanks!

[kevlahau]

Thanks for the confirmation... I'm on 12.1.1.56 so I must have a different issue "Error: Invalid parent backup"

Also seeing "Invalid parent backup" after the upgrade to 12.2.2.390

Hi David,
