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 dedicated network location that is accessible from both the CommServe hosts. If this network location is on Windows mount path, then ransomware protection is enabled by default. Use an UNC path to access the location. Ensure that this dedicated location is not used for any other CommServe task. 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.
From Local Security Policy, navigate to User Right Assignment.
Right-click Create a Token Object and then select Properties.
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\
From the navigation pane, go to Manage > System.
The System page appears.
Click the Maintenance tile.
The Maintenance page appears.
Click the DR backup (Daily) tile.
Click the edit icon .
The DR backup (Daily) page appears.
In Export Backup metadata destination, select either the Network Share or the Local Drive option.
If you select the Network Share option, specify a directory with a valid UNC network path. For example: \\server\share\path and then add the necessary credentials to access the path.
If you select the Local Drive option, 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.
The specified export location is saved.
