Database backup
Content Manager OnDemand provides the ARSDB program so that you can create backup images of the Content Manager OnDemand database.
- Content Manager OnDemand provides support for incremental table space backups and full database backups.
- An online backup can be taken when other applications or processes are connected to the database. That is, other applications and processes can continue to read or modify data while the backup is in process.
- During an offline backup, only the backup task is connected to the database. Before starting an offline backup, It is recommended that you stop the Content Manager OnDemand system to make sure that no other applications or processes are connected to the database.
- When you back up the database with the ARSDB program, Content Manager OnDemand removes the log files from the archived log file directory, releasing the space taken by files that are no longer needed. However, if you use Tivoli® Storage Manager to manage Db2® log files, then the policy domain determines when archived log files are eligible to be removed.
If your production schedule allows, It is recommended that you create offline backups on a regular schedule, perhaps once a week. Regularly scheduled offline backups can reduce the time required to rebuild table spaces or the database, if you need to do so. It is recommended that you write offline backup images to removable media or storage that is managed by Tivoli Storage Manager. Keep backup images in a safe place, until the next time that you create an offline backup image of the table space or database.
If your schedule does not provide time to take offline backups (that is, your system must always remain available to users), you should take online backups on a regular schedule. The IBM Content Manager OnDemand for Multiplatforms: Installation and Configuration Guide shows how to use the cron facility to create online backups of the database with the ARSDB program automatically on a regular schedule (for UNIX servers) and shows how to use the Windows server configuration program to schedule online backups of the database.
The IBM Content Manager OnDemand for Multiplatforms: Administration Guide provides details about the ARSDB program parameters and options.
