Understanding the Restore Options Window

Browse provides an easy-to-use convenience to search and restore data.

You can open the browse and restore window from backup-set or subclient level. The sub levels displayed in the result window is based on where you start the browse operation.

Selecting Objects from the Restore Window for Restore

The restore window displays objects and consists of two parts:

  • The left pane displays the object tree at the selected level.
  • The right pane displays the contents of the selected object.

Note that the window displays only the data that was obtained by a backup. Data that is excluded by a filter, or data which did not exist as of the specified browse time does not appear in the window.

Selections follow these rules:
  • All selections are recursive.
  • Clicking a box again causes the selection to be cleared.
  • If you select an object in the left pane, then all of its contents are selected.
  • You can select a specific object in the right pane.

Selection status is revealed by the selection icons as follows:

Indicates that the object is not selected for restoration.
Indicates that a portion of the object is selected for restoration. i.e., only some of the child object(s) within the selected object.
Indicates that the entire object, including all of its child objects, are selected for restoration.

Browse and Restore from the CommCell Console allows you browse and restore NAS data that was backed up. The browse option can be invoked from the client, agent, backup set, or subclient level.

When browsing data from NAS incremental backup jobs, deleted items are not marked as deleted.

To mark items deleted during NAS incremental backup jobs, add the following Additional Setting (see Add or Modify an Additional Setting) to the MediaAgents used to run the NAS incremental backups:

  • Name: sIdxProcessDeletedFiles
  • Category: NAS
  • Type: STRING
  • Value: Y

View Pie Charts and Size Distribution during Browse

The Show Size Distribution option displays the sizes of files and folders, as both a list and a pie chart. The depiction shows the nine largest single entities (files and folders) sorted by size (largest first), followed by a tenth item showing the sum of the remaining entities. If this option is selected, the browse results are sorted by file and folder size, largest first. If this option is not selected, the results are sorted as for Windows Explorer (folders by name on top, then files by name).

This option is applicable to File System and Simpana OnePass-enabled clients.

Browse and Restore from Copies

By default, when a browse operation is requested, the software attempts to browse from the storage policy copy with the lowest copy precedence. If the data that you want to browse was already pruned from the primary copy, the software searches the other copies of the storage policy, starting from the copy with the lowest copy precedence to a copy with the highest copy precedence.

This feature is useful in the following conditions:      

  • The media containing protected data for a particular copy has been removed from the storage library, you can choose to browse from a copy whose media are inside the library.
  • Allows browsing from a copy that accesses faster disk media rather than slower tape media.
  • When media drives used by a particular copy are busy with another operation, this helps in browsing from a different copy to avoid resource conflicts.
  1. From the CommCell Console, navigate to Client Computers | <Client> | NAS.
  2. Right-click a Backup Set and click All Tasks | Browse and Restore.
  1. From the Restore Options dialog box, click the Advanced Options tab.
  2. Select Browse from copy precedence checkbox and specify the preference number.

    If you specify a copy precedence number for a browse operation, the software searches only the storage policy copy with that precedence number in all storage policies used for securing the data. If data does not exist in the specified copy, the browse operation fails even if the data exists in another copy of the same storage policy.

List Media

List media option is useful to predict media required to restore the index required to browse data. This is useful when the index is not available in the index cache.
This option is also used to list media associated with data protection operations up to the specified date and time range.

The following section describes how to perform this operation.

  1. From the CommCell Console, navigate to Client Computers | <Client> | NAS.
  2. Right-click a Backup Set and click All Tasks | Browse and Restore.
  1. Click List Media.

    You can use the Latest Data to list media associated with the most recent data protection cycle.

    Or Specify Browse Time to list media associated with data protection operations up to the specified date and time range.

  2. From the List Media dialog box, click List Media for restore within specified time range.
  3. Click OK.
  4. The appropriate media is listed in the Media dialog box.

Browse and Restore Multiple Versions of a File

By default, the system allows you to browse and recover previously backed up versions of data. This feature allows you to restore more than one version of the same file by restoring each version individually.

If a time range browse is performed, versions are shown across cycles.

  1. From the CommCell Console, navigate to Client Computers | <Client> | NAS.
  2. Right-click a Backup Set and click All Tasks | Browse and Restore.
  1. Click View Content.
  2. From the Browse Window, right-click the file with multiple versions and then click View All Versions.

The All Version dialog box displays the available versions for the file.

Establish the Page Size for a Browse

The Page Size option allows you to specify the number of objects to be displayed in the browse window. You can browse through each page list by selecting the appropriate page number in the Browse window. Once the default is changed, it uses the same page size which was used in previous browse request until changed again.

Browse and Restore Using MediaAgent

Data can be restored from any compatible library and drive type in the CommCell. By default, the system automatically identifies and restores data from any configured library in the CommCell, even if the media is not available in the original library in which the data protection operation was performed. Use this procedure to Browse using a specific MediaAgent.

If a MediaAgent is selected for browse, the library and media that are required for restore operation must be accessible to this MediaAgent for restore. The Restore may fail if it is not accessible.
