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

A local or network path is set up as the export destination for Disaster Recovery (DR) backups during CommServe installation. You can change this location if necessary.

During the export phase of a DR backup, a metadata backup of the CommServe database 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

    • You must store the Disaster Recovery (DR) backup in a dedicated network location that is accessible from both the production host and the new server host that is used for recovery.

    • Do not use a local disk or local clustered disk because it is not safe and recommended.

    • Use a UNC path to access the network location. Make sure that this dedicated location is not used for any other CommServe task.

    • Do not use administrative shares as an export location. For example, \\MyServer\E$\.

    • For a network location that is on a Windows mount path, the software enables ransomware protection by default. For a network location that is on a Linux mount path, you must enable ransomware protection manually.

    • Do not use the Commvault installation directory as a backup location for DR backups to local disk. By default, the Commvault software enables ransomware protection for DR backup folders on Windows.

  • 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\

Procedure

  1. From the Command Center navigation pane, go to Manage > Maintenance.

  2. Click the DR backup (Daily) tile.

  3. Click Edit.

  4. For Backup metadata destination, select Network share or Local drive.

    • If you select the Network share option, specify a directory with a valid UNC network path. For example: \\server\share\path and then select or add credentials to access the path. For information about creating a credential, see Adding a Credential to a Built-in Credential Vault.

      Note

      For an export destination on a Unix computer, network share is not available.

    • If you select the Local drive option, then specify any directory on the local drive.

      For an export destination on a Unix computer, mount the path and use a local drive to store DR backups.

      Note

      If there is no library configured, it is recommended to specify a directory in a network location.

  5. For Daily start time, select the custom schedule for DR backups, if required.

  6. To reduce the size of databases during DR backup, enable the Enable compression toggle key.

  7. Click Save.

Result

The specified export location is saved.

If your existing export location is currently configured using an administrative share, administrative users will receive the Security Alert: Administrative shares configured alert, once every 24 hours.

Reconfigure the administrative using a dedicated share to turn-off the alert. For more information, see Removing Administrative Shares from Windows Servers.
