Preferences - Verifier Panel

The Backup Server stores the files that are backed up into a storage repository. This storage repository consists of the backup files and database files that track the backup files. You can instruct the Backup Server to periodically check these files. 

Database Verifier

• The Database Verifier checks the integrity of the database files that are used to keep track of the backup files. If the Database Verifier finds a problem with a database, the Database Verifier will rebuild the database using the log files that are maintained at the Backup Server. Should the Backup Server find and repair a corrupt database file, it will send this corrected database file to the backup client the next time the client logs in. This keeps the Backup Client and the Backup Server in sync.
   
• Note, when the Database Verifier runs and a Backup Client is logged in and performing a backup, that client will not be verified in order to not interfere with the backup process being performed by that Backup Client. In other words, the Backup Client's backup process is given priority over the verification process.

Storage Verifier

• The Storage Verifier performs scans through the files that have been backed up and cross checks them with the tracking databases. If this process finds that there are files that are missing from the storage repository it will inform the appropriate Backup Client to repeat the backup process on the missing files. If the verification process finds files in the storage repository that should not be present, they will be deleted to free storage space.
   
• The Storage Verification process cannot run until all Backup Clients have completed their backups. If any Backup Client is actively performing a backup, the verification will delay its start until all Backup Clients complete their backups. During the verification process all Backup Clients will be unable to login. This prevents the contents of the Backup Server from changing during the verification process.
   
• Since the process of performing a Storage Verification can take a long time, it is recommended that you run this process infrequently, such as once every two weeks.  If you discover an immediate need to perform the verification, you can press the Run Now button to start a verification immediately.
