Centralized file-level restore of a file system asset

A file-level restore enables the administrator to recover individual files from backups of file systems that were created in PowerProtect Data Manager.

Prerequisites

Ensure the following for Linux file system hosts:
  • You have enabled the SELinux nis_enabled parameter by running one of the following relevant commands:
    • RHEL 8.x or CentOS8.x: setsebool -P nis_enabled 1
    • RHEL 7.x or CentOS7.x: setsebool -P nis_enabled 1
    • RHEL 6.x or CentOS 6.x: setsebool -P allow_ypbind 1

    You can also disable SELinux permanently:

    1. Open the /etc/sysconfig/selinux file in a text editor.
    2. Change the value of SELinux=enforcing from enforcing to disabled.
    3. Restart the host machine.
    4. Verify the SELinux status by running the getenforce command.
  • You have installed the iscsiadm utility by installing one of the following relevant packages on the Linux client:
    • RHEL or CentOS: iscsi-initiator-utils<version_number>.rpm
    • SLES: open-iscsi<version_number>.rpm
  • On SLES, if you want to start the iscsiadm utility for the first time, restart the iSCSI services by running the following command: service open-iscsi restart
  • Review the section Supported platform and OS versions for file system file-level restore for supported platform and operating system versions. PowerProtect Data Manager supports file-level restore only if the backup or replica is on a DD system device.

Steps

  1. In the PowerProtect Data Manager UI, go to Recovery > Assets and select the File Systems tab.
    The Restore window displays the file systems that are available for restore.
  2. Select the check box next to the file system and click View Copies.
    You can also use the filter in the Name column to search for the name of the specific file system or click the File Search button to search on specific criteria.
    The Restore > Assets window provides a map view in the left pane and copy details in the right pane.

    When a file system is selected in the map view, the file system name appears in the right pane with the copy locations underneath. When you select a specific location in the left pane to view the copies, for example, on a DD system, the copies on that system appear in the right pane.

  3. If the backup is on a DD system, click DD, and then select from one of the available copies that appear in the table.
  4. In the right pane, select the check box next to the file system backup you want to restore, and then click File Level Restore.
    The File level restore wizard appears.
  5. On the Select target host and mount page, choose from one of the following options, and then click Mount.
    • Restore to same or original machine.
    • Restore to alternate host.
  6. When the mount is complete, click Next.
    The Select folder and files to recover page appears.
  7. On the Select folder and files to recover page:
    1. Expand individual folders to browse the original file system backup, and select the objects that you want to restore to the destination file system.
      You can also use the filter in the Name column to search for the name of the specific object.
    2. Click Next.
      The Select restore location page appears.
  8. On the Select restore location page:
    1. Select the destination drive. Alternatively, choose the Overwrite files in restore location option, in which case existing files on the destination drive will be overwritten.
      NOTE

      If you choose not to overwrite files and the file or folder has the same name as an existing file or folder, the selected file is renamed either before or after the file extension:

      • On Windows, the selected file or folder is renamed before the file extension. For example, file1.txt is renamed to file1-SSID-timestamp.txt.
      • On Linux, the selected file or folder is renamed after the file extension. For example, file1.txt is renamed to file1.txt-SSID-timestamp.
    2. Browse the folder structure of the destination file system to select the folder where you want to restore the objects.
    3. Click Next.
  9. On the Summary page:
    1. Review the information to ensure that the restore details are correct.
    2. Click Finish.
  10. Go to the Jobs window to monitor the restore.
    A restore job appears with a progress bar and start time.
