Disaster Recovery (DR) Backups are executed using the following phases:
- 
Export
During the export phase, the software copies a metadata backup of the CommServe database to the default staging directory that is in software_installation_directory\CommserveDR.
Note
The staging directory should not be on a mounted path or should not use a symbolic link. In such cases, contact your software provider to change the default staging directory.
You can specify a local path or a network path as a destination location to export the metadata.
You can set up the following additional export destinations:
- 
Commvault Cloud Services portal
 - 
Cloud storage library
 
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.
