Creating a MongoDB Subclient

You can create a MongoDB subclient.

Before You Begin

In sharded cluster MongoDB deployments, verify that the data directories are different for each shard.

Example of different data directories

  • ShardA

    Node

    Data directory

    Node1

    /dataA

    Node2 (backup secondary node)

    /dataA

    Node3

    /dataA

  • ShardB

    Node

    Data directory

    Node1

    /dataB

    Node2 (backup secondary node)

    /dataB

    Node3

    /dataB

Procedure

  1. From the CommCell Browser, expand Client Computers> client > Big Data Apps.
  2. Right-click the instance, point to All Tasks, and then click New Subclient.

    The Create New Subclient dialog box appears.

  3. On the General tab, in the Subclient Name box, enter a name for the subclient.
  4. On the Storage Device tab, from the Data Storage Policy list, select the storage policy to use for backups.
  5. Click Advanced.

    The Advanced Subclient Properties dialog box is displayed.

  6. On the IntelliSnap Operations tab, specify the IntelliSnap information:
    1. Select the IntelliSnap check box.

      A message appears stating that the next backup operation will be a full backup operation.

    2. Click OK.
    3. From the Available Snap Engines list, select the engine that matches your snapshot type.

      For a list of available engines for your array, see Snapshot Engine.

      Note: To select a native snapshot engine, verify that the LVM is configured on MongoDB data paths.

    4. From the Use Proxy list, select the MediaAgent that is used to perform the IntelliSnap and backup copy operations.

      Note: When you perform an IntelliSnap backup using a proxy, make sure that the operating system on the proxy server is either same version or or higher than the operating system on the client computer.

  7. On the Performance tab, complete the following steps:

    Best Practice: To prevent the segment hosts from waiting for resources, set the number of data readers (Advanced Subclient Properties dialog box, Performance tab, Number of Data Readers) to a value that is a multiple of the number of MongoDB shards.

    1. In the Number of Data Readers box, type a value value that is a multiple of the number of MongoDB shards.
    2. Select the Allow multiple data readers within a drive or mount point check box.
  8. Optional: Select the subclient options.
    • To run scripts before or after the operation, on the Pre/Post tab:
      1. In the Pre-Backup Command box, type the full path name for the script.
      2. In the PostBackup Command box, type the full path name for the script.
      3. To run the post backup process regardless of the job outcome, select the Run Post Process for all attempts check box.
  9. Click OK.
  10. Click OK.
