Restore Hyper-V Backup Data

In , restoring Hyper-V guest OSes is quite simple and can easily be done. The following are the steps to be followed while restoring an Exchange Server:

  • Step 0: Decide how to restore

    Decide between restoring the Hyper-V guest OS directly from the backup server or if use data which has been previously restored from the backup server (to a local folder).

    This step has the following options :
    - Restore data from backup server
    - I have previously restored data from my backup server to a local folder. I now want to use this data to restore the guest OS.

    1. If the second option is selected (to restore Hyper-V guest OS from the previously restored data), then ensure that :

      1. Hyper-V backup data was restored from backup server locally through the menu "Reseller Management->Reseller Name->Customer Name->Client Name->List of Backups->Actions->Proceed to Restore Backup" and transferred to client machine.
        or

      2. You had previously chosen the option "Restore data from backup server only (I will separately run through the 'locally restored files' to restore the Hyper-V later)" in "STEP 4: Confirm Hyper-V Restore Settings" of the Restore Hyper-V Data page (during your previous restore).

    2. Enter the local restore location and click "Submit Location" button to restore Hyper-V guest OSes from the local folder.

  • Step 1: Choose backup server (in case of multiple servers)

    This step allows you to choose the backup server (if the backup schedule was configured to multiple servers). This step has the following options:

    • Backup Name - The backup name is a non editable field here.

    • Backup Server - The backup server is non-editable if the backup schedule is backing up to only one server. But if the replication feature is enabled in the backup server for the client and replication server name is added/discovered in client machine, then choose the server from the choice box.

  • Step 2: Select backups for Hyper-V guest OS restore

    This step allows you to choose the full backup version based on timestamp. This step has the following options:

    • Show backups after - From the drop-down list, select the most recent full backup version based on timestamp to restore from. Once recent full backup version is selected and if "Load" button is clicked, will list the guest OS and its files available in the backup server.

    • Load - Once you have selected the required timestamp in the field "Show backups after", this button can be used to list the guest OS and its files backed up to the backup server for restore (satisfying the timestamp criterion).

    • Select guest OS for restore - will list the files based on what timestamp/version you have chosen in the "Show backups after" fields. Now, you will have to select the guest OS to be restored from the server.

  • Step 3: Confirm Restore Settings

    • Password - If you had password protected the backup schedule, you will need to provide the password here.

    • Restore Location - You can specify the location to which the backup data has to be restored. The restored files will be saved in this location, but with their full original path – that way you know exactly where these files were in the first place !

      Important : You must always provide an empty directory for the local restore location. There must be sufficient space in the directory to store the files; also ensure that the local restore location does not exceeds the 256 character limit.

  • Step 4: Confirm Hyper-V Restore Settings

    This step helps you restore backed up data right into the Hyper-V Manager. By default the option "Restore data from backup server only (I will separately run through the 'locally restored files' to restore the Hyper-V later)" is selected. Alternatively you can also choose the option "After restoring data from my backup server, continue to restore the guest OS into the Hyper-V Server".

    NOTE: The option "After restoring data from my backup server, continue to restore the guest OS into the Hyper-V Server" will replace the existing guest OS even if the guest OS is in running state. Restoring the guest OS will do the follow below procedure

    1. Turn OFF the guest OS if it is already available and in running state.
    2. Delete all the files available for the particular guest OS
    3. Copy the guest OS files to the original location from the restored location
    4. Register the guest OS with the Hyper-V Server.
