The schemas containing cluster configuration data and volume metadata in a pre‑existing, third-party database are critical components of BIRT iHub System. To guard against data loss, the database administrator must back up the schemas using the tools and resources of the pre-existing, third-party database system.

A BIRT iHub system administrator must take all necessary precautions to ensure that the schemas are properly backed up to safeguard the metadata. Please consult Actuate Support if you have any questions about these backup procedures to protect against the possibility of catastrophic failure. For information on the recommended procedures to back up a BIRT iHub system and volume schemas in the BIRT iHub environment, see Backing up BIRT iHub System.
