Performing a Volume Restore

This article describes the process to mount an iSCSI restore /Volume Restore from a local backup of a protected machine or iSCSI share.

Environment

  • Datto SIRIS
  • Datto ALTO
  • Datto NAS

Volume Restore

The Volume Restore feature allows you to share the contents of a selected recovery point over the LAN as an iSCSI target. All files and folders in the recovery point will restore with the ACL attributes they had when you took the snapshot.

Use a volume restore if you do not need to virtualize or perform a Bare Metal Restore of a machine, but you would like to restore files with their NTFS permissions intact.

iSCSI restore

This type of restore will create an iSCSI share from a local backup of a locally hosted iSCSI share. The primary share will still be accessible during this time and continue normal operations.

IMPORTANT  This process does not apply to externally-protected iSCSI shares. To restore a protected iSCSI share, follow the Restoring an External NAS Share process.

Procedure

  1. Connect to the Remote Web of the Datto device.

  2. Click the Restore tab to open the Restore page.

  3. For a protected system, select the desired system, then select Volume Restore. For an iSCSI share, select the desired share, then select iSCSI Restore.

  4. Select the desired recovery point, then select Restore.

  5. Datto appliances can protect iSCSI shares with CHAP authentication. Adding CHAP authentication to the share helps protect its data against networking attacks by requiring endpoints to provide access credentials to each other. To activate this feature, check the Enable CHAP authentication box. Enter the following information:

    • CHAP Username: Create a username which endpoints will use to connect to the iSCSI share on the Datto appliance.
    • CHAP Secret: Create a password 12-16 characters in length that endpoints will use to connect to the share.

    To use two-way CHAP authentication, check the Use mutual CHAP authentication box. In the fields which populate, enter the following information:

    • Mutual CHAP Username: Enter a username that the Datto appliance can use to connect to the endpoint.
    • Mutual CHAP Secret: Enter the password that the Datto appliance can use to connect to the endpoint.

    IMPORTANT  For Mutual CHAP authentication to work correctly, the CHAP secret and Mutual CHAP secret must not be the same.

  1. Once complete, click Generate Target to continue.

  2. The Datto appliance will share the contents of the selected recovery point over the network. Make a note of the Target address displayed in the Mounted Restore Options field.

  3. Follow the steps in the Mounting an iSCSI Share in Windows article to attach the recovery point as a logical drive to your production machine.

  4. When you have finished with your restore, unmount the share by using the Destroy Target button.
