Configuration of Disaster Recovery (DR) Backups

Disaster Recovery (DR) Backups are executed using the following phases:

  • Export

    During the export phase, a metadata backup of the SQL databases is copied to the default staging directory located in software_installation_directory\CS_DR.

    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.

    Additional export destination can be setup to a local or network path.

    • Note that a copy of the metadata can also be automatically exported to the Commvault Cloud Services website whenever a DR Backup is performed. This is in addition to the network share or local drive specified for DR backups.
  • Backup

    During the backup phase, the metadata available in the export destination, along with the configured log files, are backed up using the DR storage policy as follows:

    • A default DR storage policy (CommServeDR) is automatically created when the first library is configured in the CommCell.
    • A secondary copy for the DR backup data is automatically created when you configure the first tape library. An Auxiliary Copy schedule which runs every 15 minutes is automatically created. If necessary, you can change the frequency of this Auxiliary Copy operation.
