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
Notes
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 fail while the backup verification process is in progress.
Self-healing is run prior to backup verification.
Backup verification verifies all recovery points within the repository as follows:
Whether the metadata of each recovery point is in place and up to date
Whether the data of each recovery point is in place and corresponds to the checksums
Whether each recovery point is encrypted or not and, if encrypted, whether the hash required for its decryption is available
The verification results display the state of all recovery points within the repository, which can be one of the following:
OK: Metadata is in place and up to date, all data is in place and correct.
Not encrypted: Recovery point is not encrypted.
Encrypted: Recovery point and the corresponding backup object are encrypted. The corresponding password hash required for its decryption is available or is not available.
Corrupted: Any of the metadata or data is not present or not correct.
The results of recovery point full verification are marked as follows:
OK recovery points:
