Configuring a Local Drive or Network Share as the Export Destination for Disaster Recovery (DR) Backups

A local or network path is setup as the export destination for Disaster Recovery (DR) backups during CommServe installation. This location can be changed if necessary.

During the export phase of DR Backups, a metadata backup of the SQL databases is copied to the default staging directory located in software_installation_directory\CommserveDR and then exported to the specified export destination.

Before You Begin

  • Make sure the DR export location is not within the area of risk for a production CommServe disaster. The export location must be accessible by the standby CommServe host when recovering the CommServe database.

    Recommended: Store the DR backup in a network location that is accessible from both the CommServe hosts. Use an UNC path to access the location. Local disk or local clustered disk is not safe and is not a common practice.

  • If you plan to use a domain level user account for a network share, make sure the user has permissions granted to create a token object on the CommServe host.
    1. From Local Security Policy, navigate to User Right Assignment.
    2. Right-click Create a Token Object and then select Properties.
    3. Click Add User or Group. Enter the domain user account name and click OK.
  • This user account must also have read/write permissions to the following folder:

    C:\Program Files\CommVault\Log Files\


  1. In the CommCell Browser, right-click the CommServe, click Control Panel, and then click DR Backup Settings.

    The DR Backup Settings dialog box appears.

  2. In the Export Settings tab, select one of the following Backup Metadata Destination Folder Type:
    • Use Network Share
    • Use Local Drive
  3. Select the number of backup copies you want to retain in the Number of full Metadata backups to be retained box.
  4. Enter the export path in the Back Up Metadata to this Folder box. Consider the following while specifying the export path:
    • If you are exporting to a network drive, then specify a directory with a valid UNC network path. For example: \\server\share\path.
    • If you are backing up to a local drive, then specify any directory on the local drive.
    • The directory file path selected for this phase should not be located on a FAT drive. A FAT drive is not supported because it limits the file size to 4GB.
    • If there is no library configured, it is recommended to specify a directory in a network location.
  5. Click Change to specify the user account that has administrative permissions for the destination directory.

    If you are using an UNC path, you must use a qscript to change the credentials. For more information on this QScript, see Changing the Username and Password for an UNC Path.

  6. Click OK.


The specified export location is saved.
