# Restoring a Collection or a Database in a MongoDB Cluster to Its Current Location (In Place)

You can restore a collection or a database in a MongoDB cluster to its current location (in place).

## Before You Begin

- 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.
