How to export VMs from a block snapshot or replication to a filesystem

Ops Center Protector Microsoft Hyper-V Application Guide

Part Number

It is assumed that a Hyper-V policy that creates hardware snapshots or replications has been implemented and that at least one snapshot or replication has been created. See How to create VM restore points with block snapshots for guidance on how to do this.

This task describes the steps to follow when exporting VMs to a filesystem using a block snapshot or replication backup.

  1. Identify the destination where the VMs are to be exported, then ensure that it is prepared to receive them by locating the Hyper-V node in the Nodes Inventory and checking it is authorized and online.
  2. Locate the snapshot or replication to be restored by navigating to the Restore Dashboard, then click the Hitachi Block button to open the Block Restore Inventory.
    You must click the Search button to view the list of available snapshots and replications in the inventory.
  3. Click on the snapshot or replication that you want to restore to open the Block Snapshot/Replication Details.
    The snapshot or replication details are displayed, along with the list of VMs in this backup.
  4. Click Restore to open the Hyper-V Restore Wizard to restore the original VMs or create clones.
  5. Select the option to export virtual machines to filesystem. Click next.
  6. Select the VMs for the export. Click next.
  7. Specify a destination Hyper-V node and directory. Click next.
  8. Select the mount mode and specify the Mount Pool if necessary, then click Finish.
    The mount mode determines how the temporary volume, from which the backed up VM(s) are to be taken, will be created during the restore process. For replications, the mount mode is always set to Mount original.
    Select the mount mode depending on the behaviour required:
    • Mount Original - Mounts the original snapshot and exports the virtual machine data to the target location.

      This option will expose your original backup to the Hyper-V host. Any changes will persist even after the unmount. While Protector will not perform any changes, nothing is preventing users or other processes from modifying the data.

    • Mount duplicate - Protector will create a cascaded duplicate of the original snapshot and perform the restore from the duplicate. The original snapshot is preserved. Use Cascade mode (the default setting) in the Block Snapshot Configuration Wizard when assigning the snapshot operation on the data flow to enable Mount duplicate when exporting.
    A Processing message will appear briefly, then the wizard will close, and the Jobs Inventory will be displayed. A new Restore Job will appear at the top of the Jobs list, with the Progress entry initially indicating processing and finally indicating successful completion.
  9. Once the restore process is complete the virtual machine export will be available in the destination directory.
