CommServe Disaster Recovery Tool
The CommServe Disaster Recovery tool restores the metadata (stored in the CommServe SQL database) from the Disaster Recovery Backup file. This is useful if you need to restore data in the following situations:
- Rebuild the CommServe on the same or different computer
- Change the name of the CommServe computer
- Create and maintain a CommServe at the hot-site
- Update the license. (This involves using the Microsoft SQL Server (Enterprise Edition) instead of Microsoft SQL Server Desktop Engine (MSDE) as the database engine.)
- Migrate the CommServe database from either a clustered environment to a non-cluster environment, or from a non-clustered environment to a clustered environment.
- Stage the CommServe database for troubleshooting purposes
You can use the CommServe Disaster Recovery Tool to restore Disaster Recovery Backup data to the production site or a hot-site any time.
The CommServe Disaster Recovery Tool provides a more comprehensive restore operation. After a database restore, the CommServe Disaster Recovery Tool runs operations that are essential to CommServe functionality, including the following additional operations:
- Synchronizing the local setup and the new CommServe database
- Resetting all permissions by executing Setup Scripts
- Replacing the Job Result Directory in the client table of the CommServe database with the value from the Commvault registry
Perform the following tasks before attempting a restore:
- Ensure that you have a SQL Server user account. This account is required to perform Disaster Recovery operations.
Make sure the CommServe host has the same packages (for example, MediaAgent and Agents) as that of the production CommServe host. Running the restore on a CommServe host with the same packages ensures that conflicts caused by mismatched product versions or dynamic-link library (DLL) files are avoided.
- Apply the latest updates and service packs to the CommServe computer.
- Perform a full backup of the CommServe databases. This ensures that no current activity is lost.

Restore CommCell Operations
For instructions on restoring CommCell Operations by using the CommServe Disaster Recovery Tool, see Restoring CommCell Operations on the CommServe Host.
If you want to test or stage the CommServe database for troubleshooting purposes, see Staging the CommServe Database.
Post recovery operations are performed automatically after the restore job is completed. Also, you can select the Post Recovery tab separately from the rest of the tool in order to perform these operations after a database restore.
For example, if you restore a database by using Microsoft SQL Server Management Studio, you can then open the CommServe Disaster Recovery tool, select some of the postrecovery options, and then run the tool to complete these operations.
For more information on the post recovery options, see CommServe Disaster Recovery Tool - Postrecovery Options.
