Monitoring the fingerprint databases

If you enable monitoring on the Monitoring tab of the Site Properties, a number of alerts are available for the vault store group fingerprint databases. These alerts are as follows:

Vault Store fingerprint database backup. The number of days before Enterprise Vault issues a warning about a fingerprint database that is not backed up. The default value is 3.
Vault Store fingerprint database log backup. The number of days before Enterprise Vault issues a warning about a fingerprint database transaction log that is not backed up. The default value is 1.
Vault Store fingerprint database log size. The percentage of available space that a fingerprint database transaction log can occupy before Enterprise Vault issues a warning about space usage. The default value is 85 percent.

See Monitoring in Site Properties.

The fingerprint databases must be backed up as part of your backup regime.
