Error message Backup Copy Job "Failed to perform backup verification Error: Unable to get block digest: block is not initialized. "

Hello everyone,

For several days now, I have been receiving the following error message during our backup copy job:

“Failed to perform backup verification Error: Unable to get block digest: block is not initialized. Skipped arguments: [0]; Agent failed to process method {Signature.FullRecheckBackup}.”

I performed a full backup, but unfortunately the same error message appeared again. The copy job does not conflict with the backup job.

How can I fix this error?

Thanks in advance!

Hi ​@er_mat,

Welcome to the community!

To assist with this we do need a few more information. You have a copy job - what are your source backups (e.g. VM backups from vSphere, Hyper-V etc.)? What is your target repository for the copy job? Have there been any changes in the past days / weeks that could cause this? What Veeam version are you running?

 

In general, we are a community but cannot provide technical support in depth. In this specific case I strongly recommend to open a Veeam support ticket, they can help on a deeper level then we can do.

Anyways, please do not hesitate to update us on the topic, we are always happy to be of assistance.

 

Best regards
