Using the BAR interface to restore the MongoDB data on an alternate cluster

NetBackup supports the following alternate recovery scenarios for MongoDB:

  • Redirected restore and recovery to an alternate cluster

  • Redirected restore and recovery to an alternate node or port or database path in an existing cluster

Complete the following steps to run alternate recovery for MongoDB:

  1. Run the tpconfig command to update the original cluster's credentials with the alternate application server's credentials.

    For example, to recover source client Host1-26050 to an alternate application server Host2 that is running on port 28001:

    • Add the credentials of Host2:28001 and its related nodes in the original cluster's credential configuration file. For more information, See About the credential configuration file.

    • Run the update tpconfig command for application_server that is getting recovered (Host1-26050)

    Here is a sample command:

    /usr/openv/volmgr/bin/tpconfig -update -application_server Host1-26050 -application_type mongodb -requiredport 26050 -application_server_conf /usr/openv/var/global/credential.conf

  2. Rename the application server and its nodes and set the value for the alternate application server.

    • In the BAR UI select the General tab > Restore individual directories and files to different location and use Change Selected Destination(s) to add the alternate application server and port.

    • To change the folder path, select Add Destination and add the new destination path.

    See Alternate restore from a nested database path.

  3. Click Start Restore to start the recovery operation. You can check the status from the Activity Monitor.

Restoring the MongoDB oplog file to an alternate temporary location

You can restore the MongoDB oplog files from an incremental backup to an alternate path. The files and their path are seen in the BAR UI.

You must specify the paths during the alternate restore using the Restore individual directories and files to different locations option.

If you want to retain the original MongoDB path but change the oplog file path, in the Add Destination dialog box, specific the source and alternate paths.

For example, Source /host:port/tmp and Destination /host:port/alternate_tmp.

Alternate restore from a nested database path

For an alternate restore from a nested database path, use the Add Destination dialog box and for every subfolder, add an appropriate target alternate path.

For example, to change the path from /host:port/usr/mongodb/db1 to /host:port/alt-dir/dbpath/mydb:

  • Specify the source and the destination path:

    Source /host:port/usr/mongodb/db1 and Destination /host:port/alt-dir/dbpath/mydb

  • Specify the source and the destination path for the parent folder:

    Source /host:port/usr/mongodb and Destination /host:port/alt-dir/dbpath

  • Specify the source and the destination path for the base parent folder:

    Source /host:port/usr and Destination /host:port/alt-dir

    Note:

    When you do an alternate restore to a non-root path, the restore is partially successful if the database path contains multiple subfolders.

    In such a scenario, when you do an alternate restore to a different location, you must add an entry for each directory level.

    For example:

    Source:/hostname1:port1/Config_Data

    Destination: /hostname2:port3/mongo_inst2

    Source:/hostname1:port1/Config_Data/data

    Destination:/hostname2:port3/mongo_inst2/data

    Source:/hostname2:port2/Shard1_Primary

    Destination:/hostname2:port3/mongo_inst2

    Source:/hostname2:port2/Shard1_Primary/data

    Destination:/hostname2:port3/mongo_inst2/data

Restoring a MongoDB cluster where the backups are taken from different MongoDB nodes in the same replica set

You can restore a MongoDB cluster (sharded or replica set) that was backed up from different nodes because of the role switch (between primary and secondary nodes) within a shard or replica set. In such a scenario, the full backup can be taken from one host and incremental backup is taken from another host in the same shard or replica set.

During restore, you must redirect the restore of these backup images to the same MongoDB host.

For example, to restore backups from /host1:port1/dbpath and /host2:port1/tmp, specify the following:

Source /host1:port1/dbpath and Destination /althost:port1/dbpath

Source /host2:port1/tmp and Destination /althost:port1/tmp
