Restoring NAS File System Data from Archive Storage

While restoring NAS File System data from Archive Cloud Storage platforms, the restore job may fail prematurely. This is because the NAS restore jobs are not restartable. Use the following steps to successfully restore NAS File System data:

Procedure

  1. To the CommServe computer, add the nCloudChunkRecallIgnoreJobStatus additional setting as shown in the following table.

    For instructions about adding an additional setting from the CommCell Console, see Adding an Additional Setting from the CommCell Console.

    Property

    Value

    Name

    nCloudChunkRecallIgnoreJobStatus

    Category

    CommServe

    Type

    Integer

    Value

    1

  2. To the MediaAgent hosting the Index Server, add the DO_NOT_DELETE_RESTORE_VECTOR additional setting as shown in the following table. Make sure to add the key using upper case letters. The key is case sensitive.

    For instructions about adding an additional setting from the CommCell Console, see Adding an Additional Setting from the CommCell Console.

    Note: The Lookup feature will not work for the DO_NOT_DELETE_RESTORE_VECTOR additional setting and you must manually add the details in all the relevant fields.

    Property

    Value

    Name

    DO_NOT_DELETE_RESTORE_VECTOR

    Category

    Event Manager

    Type

    Integer

    Value

    1

    Perform the following steps to determine the MediaAgent hosting the Index Server:

    • From the CommCell Browser, navigate to the NAS File System client containing the data that you plan to restore.
    • Right-click the <BackupSet> containing the data and then click Properties.
    • Click the Index tab.

      The Index Server option displays the name of the MediaAgent hosting the Index Server.

  3. Initiate the restore for NAS File System data.

    This will automatically start the Cloud Storage Archive Recall workflow.

    However, both the workflow and restore jobs may fail if the index needed to restore the data is not available.

    Tip: Note down the Job ID associated with the restore and workflow jobs.

    Note: If the subclient containing the NAS File System data was backed up using a storage policy with a Snapshot Copy, make sure to set the Copy Precedence associated with the Primary Copy when you initiate the Browse and Restore operation. For information on setting the copy precedence, see Restoring Data from a Specific Copy.

  4. Login to the MediaAgent hosting the Index Server.
  5. Rename the restore vector folder as follows:

    For V2 Index

    • Navigate to the restore vector folder found in the following location:

      <Index Cache Folder>\CvIdxDB\Temp\<Job ID>_restore_<time stamp>

      The path to the <Index Cache Folder> is displayed in the MediaAgent Properties - Catalog tab, Index Directory option.

    • Rename the folder as follows:

      <Job ID>_restore_<time stamp> to <Job ID>_restore

    For V1 Index

    • Navigate to the restore vector folder found in the following location:

      <Index Cache Folder>\CV_Index\restores\<time stamp>_<Job ID>

    • Rename the folder as follows:

      <time stamp>_<Job ID> to <Job ID>

  6. Re-submit the original Cloud Storage Archive Recall workflow job.

    This will recall the data from the respective Archive Cloud Storage in which it is stored.

    Note that the recall may take some time, depending on the amount of data requested in the restore.

    Wait for the workflow job to complete successfully.

  7. Re-submit the original restore job.

    This will restore the data from the recalled data to the destination specified in the restore job.

  8. Delete the DO_NOT_DELETE_RESTORE_VECTOR additional setting that was added in <Step 2> on the MediaAgent hosting the Index Server.
