Docs latest icon.png Welcome to the latest SEP sesam documentation version 4.4.3 Grolar/4.4.3 Beefalo. For previous documentation version(s), check Hyper-V archive.


Overview

SEP sesam enables you to restore individual VMs that were backed up from a Hyper-V standalone server or a Hyper-V cluster. Only one VM can be restored at a time, regardless of whether you are using a Hyper-V standalone server or a Hyper-V cluster backup.

As of v. 4.4.3 Grolar, you can restore single files from the FULL or COPY backups if the saveset is stored on a data store or Si3 deduplication store. Additionally, as of v. 4.4.3 Beefalo, you can also restore single files from the INCR backups. By mounting VHD or VHDX the operating system creates a virtual drive from the file, assigns one or several drive letters, depending on the number of disks of the VM, and makes the drive(s) available locally on your device server. For details, see section Restoring single files.

Restore options

The following options are available when restoring Hyper-V:

  • Restore a backed up VM or perform single file restore from a FULL, COPY (v. ≤ 4.4.3.64 Grolar) or INCR backup (v. ≥ 4.4.3.65 Beefalo) of Hyper-V VM.
  • Select a specific Hyper-V version for restore.
  • Select a complete, generation or as path restore.
  • Select an alternative location to restore your data:
    • restore a VM to the original or a different location (including CSV and SMB 3.0) with the same or a different VM name using relocation
    • restore a VM to the same or a different Hyper-V standalone server and to the same or a different Hyper-V cluster
    • perform a simple path restore of your selected Hyper-V data directly to a directory on any system instead of restoring and importing the VM to the Hyper-V manager
  • In ≥ SEP sesam Beefalo, if you are performing a standard VM restore you can also select whether you want your virtual machine to start automatically after restore.
  • Schedule a restore task.

Restoring a Hyper-V virtual machine

Information sign.png Note
GUI has been largely improved with SEP sesam 4.4.3 Beefalo, thus your display may vary slightly from what is shown here. If you are using an older SEP sesam version (≤ Grolar), some actions that you perform in the following steps may not be available or may be slightly different so make sure to follow the version-specific instructions.

Create a new restore task for the VM you want to restore.

  1. From the SEP sesam GUI menu bar, select Activities -> Restore. The New restore task window opens.
  2. Select what you want to restore. You can search savesets by task name or by filename or path.
    • When searching by task name, use the drop-down list of available tasks and select the one you want to restore from. This option is selected by default.
    • If you are searching by filename/path, select the option Filename or path in saveset and enter your search expression in the search pattern field.
  3. From the drop-down list under the Saved in period, specify the time frame for which you want to conduct the search. Click Next.
  4. Hyper-V restore filter.jpg
  5. The search results are displayed. From the list of savesets matching your query, select the task you want to restore. Click Next.
  6. Hyper-V restore select task Grolar.jpg
  7. Data from the selected saveset is displayed in a hierarchical tree structure. Select your Hyper-V server, then select the VM you want to restore. Click Next.
  8. Hyper-V restore select files.jpg
  9. Review your restore task configuration and set additional options if necessary.
    • Details of the selected saveset are displayed at the top of the window. The name of the restore task is automatically generated in the Name field. You can edit the name and insert a comment below.
    • The Drive field shows the drive with backed up data.
    • The Interface field shows the server (RDS server or SEP sesam Server) with the attached data storage containing the selected saveset.
    • The Target Node drop-down list shows the target server to which the data will be restored. To restore a task from a cluster to a different standalone server, select the appropriate Hyper-V target node.
    • Under the Target Path Settings, select Restore to new VM. You can enter the target path or browse for it. If no target path is defined, the VM is restored to the default location of the Hyper-V standalone server or Hyper-V cluster.
    Make sure that the target host can support the VM type you want to restore. For details, see Hyper-V troubleshooting.
    Information sign.png Note

    SMB3 restore with relocation. Check the New restore target option. You can enter the target path by using UNC notation \\smbshare\Hyper-V\newVM. If no target path is defined, the VM is restored to the Hyper-V server default location.

    • Depending on version, under the VM restore options (version ≥ Beefalo) or Execution options (version ≤ Grolar) drop-down list, select one of the following options:
      • do not overwrite existing files (set by default): the VM will not be restored if it already exists on the target server
      • overwrite existing files: if a VM exists on the target server, it will be replaced by the restored version
    • In ≥ Beefalo, if you are performing a standard VM restore you can also select whether you want your virtual machine to start automatically after restore by selecting Do not start (default) / Start virtual machine after restore.
    • Click the Expert options button if you want to specify additional restore settings (e.g., to modify the log level, define the pre/post script for restore, or use As path backup option if you want to restore your data directly to the file system). For details, see the Restore wizard.
    Information sign.png Note
    As of v. 4.4.3. Beefalo, the Expert Options button for specifying more advanced restore options is only available in the Advanced and Expert UI mode. It is not available for users that run the GUI in Basic mode. In the latter case, you first have to change the Basic UI mode to Advanced or Expert, as described in UI Mode.

  10. If you want to start your restore immediately, click Start. If you want to save the restore task, click Save.

A restore task can be scheduled like any other task. If you want to add a restore task to the schedule, see Scheduling Restore.

Restoring single files

SEP sesam enables single file restore – item-level restore of files, folders, and volumes from a COPY, FULL (v. ≤ 4.4.3.64 Grolar) or INCR backup (v. ≥ 4.4.3.65 Beefalo) of Hyper-V virtual machine by mounting VHD or VHDX on a device server and browsing the content of a virtual disk file.

The procedure for restoring single files from a COPY, FULL or INCR backup is the same, except with v. 4.4.3 Beefalo SEP sesam GUI has been redesigned to be more user-friendly without significantly changing the interface logic.

Information sign.png Note
You can only perform a single file restore by using the same SEP sesam version as the one used for backup. If you have performed a Hyper-V VM backup with v. 4.4.3 Grolar, you cannot perform a single file restore with v. 4.4.3 Beefalo.

Before starting a restore, check the supported file systems and restrictions. Note that the following additional restrictions apply for mounting and single file restore on Hyper-V:

  • You can only perform single file restore on a Windows Server/RDS since you need the PowerShell in order to execute it.
  • You can only mount Windows VMs due to the underlying file system.

Mounting Hyper-V virtual disk (VHD or VHDX file)

Create a new restore task for individual item(s) you want to restore.

  1. From the SEP sesam GUI menu bar, select Activities -> Restore. The New restore task window opens.
  2. Select what you want to restore. You can search savesets by task name or by filename or path.
    • When searching by task name, use the drop-down list of available tasks and select the one you want to restore from. This option is selected by default.
    • If you are searching by filename/path, select the option Filename or path in saveset and enter your search expression in the search pattern field.
  3. Under the Saved in period drop-down lists, specify the time frame for which you want to conduct the search. Click Next.
  4. The search results are displayed. From the list of savesets matching your query, select the version from which you want to restore an individual file. Then select the check box Mount virtual disk(s); refer to the general restrictions and note that some additional Hyper-V restrictions apply.
  5. Hyper-V restore mount Grolar.jpg
  6. Mount is triggered and all VHD/VHDXs of the selected VM are mounted to the device server using one or more unused drive letters of the Windows system e.g., D:, E:, etc. This may take a few seconds.

  7. You can now either click Next to select the required files in the Select Files dialog or use the file explorer on your server to browse and copy the needed files directly to the target location, as shown in the screenshot below.
  8. Hyper-V file explorer.jpg
  9. If you clicked Next, in the Select Files window select the data you want to restore and click Next.
  10. Hyper-V restore single file Grolar.jpg
  11. On the last step of the restore wizard, select a restore target where you want to restore your files.
  12. You can start your single file restore immediately by clicking Start. If you want to save the restore task, click Save.
  13. Click Next to unmount the saveset and close your restore session.
Information sign.png Note
A restore task can be scheduled like any other task. If you want to add a restore task to the schedule, see Scheduling Restore.

You can view the status of your restore jobs by selecting Job state -> Restore from the Main selection. Restore overview provides detailed information on the last run of restore jobs, including the task name, status (successful, error, in queue ...), start and stop time of the last backup, data size, throughput, client and message.
