Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.
Overview of backup and restoreThese topics provide an overview of backup and restore concepts. They also provide information about planning for backup and restore operations.
Plan for backup and restoreThese topics describe the planning for backup and restore, for example by planning your recovery strategy and backup system.
Plan a backup system for a production database serverTo plan for adequate backup protection for your data, analyze your database server configuration and activity and the types of backup media available at your installation.
Transform data with external programsYou can use external programs as filter plug-ins to transform data to a different format before a backup and transform it back after the restore.

Transform data with external programs

You can use external programs as filter plug-ins to transform data to a different format before a backup and transform it back after the restore.

To compress or transform data, use the BACKUP_FILTER and RESTORE_FILTER configuration parameters to call external programs.

Tip: If you compress row data before backing it up, compressing the backup image with an external utility might not result in a smaller backup image.

The filter can be owned by anyone, but cannot have write access to non-privileged users. Permission on the filters is the same as that of permission on any other executable file that is called by the HCL OneDB™ server or HCL OneDB utilities.
