Verify Volume Metadata Integrity

As reading the complete stored data is expensive in terms of network bandwidth, CPU cycles, and storage I/O used, Bacula allows to compare the metadata read from the media against what it stored in the catalog. With Bacula, this comparison is done on a Job-by-Job basis; other backup systems often verify complete volumes.

This sort of Verify Job is called a VolumeToCatalog verification. How to set up and run this sort of Job is explained in detail in chapter Volume to Catalog Verification.

These verifications are a bit more efficient in terms of storage bandwith consumption than the previously described data verifications, and they also help ensuring the catalog matches what is stored on the Volumes, i. e. they get a step further towards actual end-to-end data verification, including the middle layer of the Bacula catalog.
