Backup and Failover

Tenable Security Center encourages all organizations, but especially large organizations, to maintain Tenable Security Center backups for disaster recovery.

Consider the following when planning and performing your backup:

• In general, linked scanners (e.g., Tenable Nessus scanners) do not need to be backed up since they do not permanently store vulnerability data.

• In general, vulnerability trending snapshots consume the most storage in Tenable Security Center deployments. Consider creating a separate backup policy for this data; once Tenable Security Center creates the nightly vulnerability trending snapshot, the data does not change.

• Tenable does not recommended backing up volatile directories (for example, /opt/sc/admin/tmp and /opt/sc/data/scans).

• Since Tenable Security Center does not encrypt most data on disk, consider encrypting your backups.

Tenable Security Center does not support high availability failover scenarios, but you can maintain a cold standby system using system backups.
