Restore a NAS share

Phoenix Editions: File:/tick.png Business File:/cross.png Enterprise File:/tick.png Elite

This section provides information about the restore options for NAS share and describes how you can restore data to the original or an alternate location.

About NAS share restore

Phoenix provides the following  restore options for NAS share:

  • Restore back to NAS Filer: Restores the data at the original location with the original settings.
  • Restore to alternate location:  The alternate location can be a different NAS share of the same server or a different NAS share of a different NAS device. You can also restore on a NAS device in a different administrative group.

You can configure both the above restore options with a set of restore settings common across both the options. The common restore settings control how Phoenix restores the NAS share data when the data is likely to get duplicated or overwritten at the restore location. 

Common restore settings

The following restore settings define how data restore occurs if the files and folders already exist at the target location. These settings are common to both Restore back to NAS Filer and Restore to alternate location restore options.

  • Always overwrite: The files with the same name will always be overwritten at the destination regardless of the file version or date. This is the default restore setting.

  • Always skip: Phoenix does not restore files with the same name at the restore location. The number of files skipped will be displayed in the progress logs.

  • Overwrite if original is older: The files with the same name will be overwritten only if they are older than the version being restored.

  • Restore and move original to .orig: If Phoenix detects the same file name at the restore location, it renames it to filename.ext.orig and completes the restore. Hence the file names at the restore location are appended with an incremental number,  such as filename.ext.orig1filename.ext.orig2, and so on in the subsequent restores.

    Example: Assume that one of the files you are restoring from Phoenix is “foo.txt” which already exists at the destination. This scenario will explain the naming changes that foo.txt undergoes over several restore cycles.

  • First Restore Operation: The “foo.txt” file which already exists at destination will be renamed to “foo.txt.orig” while the file being restored will be saved as “foo.txt”.
  • Second Restore Operation: The existing “foo.txt” will be renamed to “foo.txt.orig1” while the file being restored will be saved as “foo.txt. You will now see three versions at the destination:
    • foo.txt.orig - The oldest version present on the destination server.
    • foo.txt.orig1 - The version restored as part of the previous (first)  restore operation.
    • foo.txt - The latest version restored from Phoenix
  • Preserve upward tree path: You can preserve the entire source location, that is tree path while restoring a file to an alternate location.

    An example of upward tree path: If you are restoring folder “B” from the source location  E://A/B/C/D to  F:// drive.

    The restored file structure will be  F://E/A/B/C/D.
    Upward tree path is preserved in case you are restoring to the original location. The Downward folder structure is always preserved.   

Restore a NAS share to the original server 

  1. Log on to Phoenix Management Console.
  2. On the menu bar, click All Organizations, and select the organization containing the NAS device.
  3. On the menu bar, click NAS.
  4. Click the NAS device containing the NAS share that you want to restore.
  5. Select the NAS share that you want to restore and click Restore.
  6. On the Restore Data window:
    1. Under Backup Sets, select the backup policies from which you want to restore.
    2. Under Snapshots, select one of  the following:
      • Hot snapshotsIn the left pane, expand Hot, and click the snapshot that you want to restore. 
      • Warm snapshots In the left pane, expand Warm, and click the snapshot that you want to restore. 
      • Thawed snapshots In the left pane, expand Thawed, and click the snapshot that you want to restore. 
    3. In the right pane, select files and folders, and click Restore.
  7. On the Restore page, select Restore back to NAS Filer and click Next.
  8. Under Restore Settings select one of the following. See Common restore settings above for more information.
    • Always overwrite
    • Overwrite if original is older
    • Restore and move original to .orig 
    • Always skip
      Note: The above restore setting will be displayed only if you have upgraded the File server client to version 4.6.9 and later.

  9. To restore the parent folders during restore, select Preserve upward tree path option. 
    Note: The upward tree path is always preserved while restoring to the original location. 
  10. Click Finish. Phoenix will perform restore of the NAS share data to the original location based on your selected restore settings. 
     
    Note: Symbolic links and mounted folders do not appear in the folder structure. If the server is not connected to Phoenix Cloud, Phoenix cannot fetch the folder structure data. To initiate a restore, you must type the absolute path to the restore destination. The restore operation fails if the server is not connected to Phoenix Cloud with PHOENIX17  error.
