Running Block-Level Backup Verification
Block-level backup verification reads each block of data in a Backup Repository, makes a hash of each data block, and then compares the newly created hashes to the originals that were created during the backup process. If the hashes match, this means that the data blocks in the Backup Repository are identical to the data blocks that were read on the source machines. This way, NAKIVO Backup & Replication verifies that backups are good and recoverable.

Verifying Backups
Note
Before backup verification begins, the Backup Repository is detached from the product to keep data in a consistent state. Backup jobs that write data to such a Backup Repository will fail while the backup verification process is in progress.
