Performing an Encyclopedia volume backup
When performing a backup, it is important to note that there are two types of data:
Metadata
Information about iHub system and Encyclopedia volume settings and data objects stored in third‑party relational database management system (RDBMS) schemas.
Data
iHub system and Encyclopedia volume data objects, such as designs, documents, and information objects, stored as files on disk partitions, and the acserverconfig.xml file containing iHub configuration information.
The administrator must back up all Encyclopedia volume metadata and data to ensure the recoverability of a volume in the event of failure. In iHub, it is not necessary to back up the iHub system schema, although future versions may require this operation to protect critical system metadata. The administrator can restore a corrupted or missing system schema using the System Data Store Administrator utility. For more information on this utility, see
“Specifying System Data Store Administrator properties” in
Chapter 11, “Working with BIRT iHub utilities.”The third‑party database that contains Actuate Encyclopedia metadata is a critical component of BIRT iHub System. An Actuate system administrator must take all necessary precautions to ensure that this database is properly backed up and available to safeguard Encyclopedia volume metadata. Please consult Actuate Support at the time of installation if you have any questions about the backup, recovery, or failover procedures necessary to protect against the possibility of catastrophic failure.
