Backing up user data

All IBM® Sametime® Advanced user data is stored in an IBM DB2® database, and can be backed up using the DB2 backup commands.

About this task

The default Sametime Advanced configuration requires that DB2 be shut down for backup. This is because by default, DB2 is configured to reuse the recovery logs. If you want online backup, the database can be configured to archive the recovery logs. In that case, the database is backed up, and all archived recovery logs are backed up. The recovery logs that have been backed up must also be periodically removed. If the database runs out of space to archive the recovery logs, the database will stop accepting changes until space is available.

Database backup and recovery is fully outlined in the topic Developing a backup and recovery strategy, in the DB2 product documentation.

The only special backup consideration for Sametime Advanced is that because the full text indexes are maintained outside of the database tablespaces, after a restore operation the dbtext.sh or dbtext.bat scripts should be run to drop and recreate the text indexes to match the restored data in the database. You can find these scripts at CD1/SupportingFiles/DB2.
