Veeam Backup Validator - similarly?

[Deansbkk]

Hello all, Regarding https://helpcenter.veeam.com/docs/backu ... ml?ver=110 it states

"Veeam Backup Validator is a command-prompt CRC check utility that tests a backup at the file level. For integrity validation, Veeam Backup Validator uses the checksum algorithm. When Veeam Backup & Replication creates a backup of a VM, it calculates a checksum for every data block in the backup file and attaches these checksums to the data blocks. Veeam Backup Validator re-calculates checksums for data blocks and compares them against the initial checksum values. If the results match, the backup file is viable. This works similarly to the backup file integrity check performed at SureBackup."

I would like to understand why it states "similarly to the backup file integrity check performed at SureBackup". Is Veeam Backup Validator actually performing the exact same validation or is something more/less happening when SureBackup runs the backup file integrity check?

Hello,
agree, the sentence is unclear. The checksum comparison is the same (if we talk about the "validate entire virtual disk content" checkbox)

SureBackup additionally does tests whether the machine boots, services come up etc.

Health check https://helpcenter.veeam.com/docs/backu ... ml?ver=110 does the same CRC validation by the way.

Best regards,
Hannes

Hello Hannes,

Yes I was talking about SureBackup "validate entire virtual disk content" checkbox.

Regarding Health check https://helpcenter.veeam.com/docs/backu ... ml?ver=110 I was wondering about that so thank you for mentioning it.

It seems if we use SureBackup "validate entire virtual disk content" checkbox for every backup then it is pointless to periodically run the Health check https://helpcenter.veeam.com/docs/backu ... ml?ver=110 in the backup itself. Do you agree with that?

Hello,
yes, agree. That would be double-check.

Best regards,
Hannes
