Failed to compress index errors in NetVault and system logs (4033583)

Getting errors in NetVault Binary logs and System Logs/Event Logs:

"Failed to compress index"

The cause ot these errors is due to corrupt indexes in the NetVault Media Database. Running a NV Media DB check from the command line will indicate this as seen below:

Backup 18473 has corrupt index file (E:\Program Files (x86)\Quest Software\NetVault Backup\db\MediaDatabase\Files\Backup\0000\48\29) - delete the index file and recover the index from tape

Backup 18474 has corrupt index file (E:\Program Files (x86)\Quest Software\NetVault Backup\db\MediaDatabase\Files\Backup\0000\48\2a) - delete the index file and recover the index from tape

Backup 18475 has corrupt index file (Backup 18473 has corrupt index file (E:\Program Files (x86)\Quest Software\NetVault Backup\db\MediaDatabase\Files\Backup\0000\48\29) - delete the index file and recover the index from tape

To fix this issue, navigate to the location of the corrupt index as referenced by the DB Check, for example:

E:\Program Files (x86)\Quest Software\NetVault Backup\db\MediaDatabase\Files\Backup\0000\48\29

The files in this location will most likely be 0 byte files. Delete these and any others that are referenced.

The proper procedure for the deletion is as follows:

1. Run a NVDB Backup
2. Stop the NV Service
3. Run the NVMEDDBCHECK syntax
4. Get the list of the indexes that the check references
5. Navigate to the path and delete the files

Once this is done, start the service back up. If needed, scan in any media that might appear as foreign or unknown.

You should no longer see these errors in the logs.
