Restoring a Collection or a Database in a MongoDB Cluster to to a Different Cluster (Out of Place)

You can restore a collection or a database in a MongoDB cluster to a different cluster (out of place).

Before You Begin

• Verify that the MongoDB system meets the following requirements for out-of-place restores:

  • In a sharded cluster environment, the source and destination shard configurations must be the same.

  • The destination must have the same version or a more recent version of MongoDB than the source.

• Verify that the MediaAgent that hosts the 3DFS server meets the requirements for 3DFS.

• To restore to a Windows MongoDB cluster, verify that the UNIX MediaAgent and the pseudoclient master node are in the same domain. On the UNIX MediaAgent, install the wbinfo program using the samba-winbind-clients RPM package.

• Provide user credentials to access the share exported to the Windows MongoDB cluster.

• Verify that the backup copy job is completed.

• If there is a firewall between the MongoDB node and the MediaAgent, verify the following ports are open:

  • For the MediaAgent on a Windows computer, open 111, 2049, and 2050.

  • For the MediaAgent on a Linux computer, open 111 and 2049.

• To specify additional arguments to the mongodump process that is started during granular recovery, set the sGranularRestoreMongodumpArgs additional setting.

• To specify additional arguments to the mongorestore process that is started during granular recovery, set the sGranularRestoreMongorestoreArgs additional setting.

Procedure

1. From the navigation pane, go to Protect > Big data.

   The Apps page appears.

2. In the row for the cluster, click the action button , and then click Restore.

   The Backup content page appears.

3. From the list beside the Restore button, select Restore collections.

4. Select the database or a collection to restore, and then click Restore.

   The Restore dialog box appears.

5. On the Out of place tab, from the Destination cluster list, select a different cluster.

   By default, the current cluster is selected as the destination.

   Note: During a granular restore, a MongoDB staging server is started automatically and does not have the TLS or authentication enabled on it. After the restore operation is complete, the server is deleted.

6. Click Submit.
