Performing Disaster Recovery (DR) Backups
You can initiate disaster recovery (DR) backups for CommServe databases.
Before You Begin
- Login to CommCell Console as user with CommCell level Administrative Management capability.
- Make sure CommCell services are running on the CommServe host.
About This Task
By default, a full disaster recovery (DR) backup is performed daily for any CommServe database. Based on the security requirements of a CommServe and recovery point objective of the disaster recovery plan, you can schedule the disaster recovery backup jobs several times in a day. For more information on scheduling DR backups jobs, see Schedule Disaster Recovery Backups.
A disaster recovery plan should consist of at least one full backup performed every day and full or differential disaster recovery backups performed several times in a day. Differential DR backups will back up only that data that has changed since the last full backup. This backup smaller in size and takes less time to complete.
A disaster recovery backup job has the highest priority. If a Disaster Recovery backup job cannot be completed, the Job Manager will retry the job up to a total of five hours at 30-minute intervals for a maximum of 10 times.
- For minimum impact to production jobs, we recommend performing disaster recovery backups when no other CommCell jobs are running.
- If the Workflow Engine and Metrics Reporting Server are installed on the CommServe host, by default, the WFEngine and CVCloud databases are included in the Disaster Recovery backup job. We recommend that you do not exclude any database from the backup job.
- From the CommCell Browser, right-click the CommServe and select All Tasks > Disaster Recovery Backup.
- In the General tab of the Disaster Recovery Backup Options dialog box select the one of the following backup type:
- Full - Back up the entire metadata. By default a Full backup type is selected.
- Differential - Back up only that data that has changed since the last full backup. This backup is smaller in size and takes less time to complete. You can use this backup to restore the database only if the last full backup is accessible. Use differential backup type if there are limitations in disk space or network bandwidth.
- If sufficient space is not available on the CommServe host, to compress the database backup file (*.dmp), select the Enable database(s) backup compression check box.
- Click the Client Selection tab to back up the log files from clients in the CommCell.
- Select the Client(s) from the available list of Clients and click OK.
You can also select MediaAgent clients to back up the log files from MediaAgents. This is useful for troubleshooting purposes, especially in Deduplication configurations.
For more information on the backup options, see Disaster Recovery Backup Options.
For each Disaster Recovery Backup, SET_XXX directory is created under the configured export location. xxx is a sequential number for the directory. The highest number is associated with the latest disaster recovery backup. It contains the following files:
|commserv_FULL.dmp||This full dump file represents a full backup of the CommServe database.|
|commserv_DIFF_xxx.dmp||This dump file represents a differential backup of the CommServe database.|
|Other Files||Depends on the software module installed/configured, e.g., workflow database files.|
