# Configuring a Cloud Library as the Export Destination for Disaster Recovery (DR) Backups

You can configure a cloud storage as the export destination for Disaster Recovery (DR) backups.

Note

If you plan to change or switch to another cloud storage, consider the following:

- Run a full DR backup job after the change.

- Manually prune existing DR backup jobs from the original cloud storage library.

## Before You Begin

- Configure the cloud storage that you plan to use for the DR export destination as a storage device and note the name of the storage.

  For more information about configuring a cloud storage device, see Configuring Cloud Storage.

- Ensure that the CommServe can connect to the cloud storage to upload DR backups directly by configuring the required network and firewall settings.

- If the CommServe connects to the cloud storage through a proxy server, ensure that the proxy details are configured in the cloud storage properties. For more information, see Setting up a Proxy Server to Access the Cloud Storage Library.

- When using Amazon S3 as the destination, if the CommServe is on-premises, use the access key and secret key as credentials because the data is sent directly from the CommServe to the cloud storage.

## Procedure

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

2. Click the DR backup (Daily) tile.

3. Click Edit.

4. Enable the Upload backup metadata to cloud library toggle key.

5. From the Cloud library list, select the cloud storage to store the DR backups.

   Notes

   - Cloud storage names that use Unicode characters are not supported.

   - Air Gap Protect cloud storage is not supported. Instead, use the Upload to Commvault cloud option.

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

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

8. Click Save.

## Result

The specified cloud storage is configured as the export destination.

## What to Do Next

Run a Full DR backup job after configuring the cloud library as the export destination. If a Differential DR backup job runs without a corresponding full backup, the backup cannot be restored.
