Overview

As of SEP sesam v. 5.0.0 Jaglion, SEP sesam provides efficient data protection for Nutanix Acropolis Hypervisor (AHV). The Nutanix AHV module is supported on SEP sesam Linux Server and on SEP sesam Windows Server, using a Linux Client as a data mover.

The restore of Nutanix virtual machines (VMs) is quite similar to a regular file system restore. There are two ways to restore your Nutanix virtual machines (VMs): using the GUI restore wizard or via the web interface Restore Assistant. Although most options are the same in both restore interfaces, the web Restore Assistant is more intuitive and offers additional advanced options. Note that scheduling restore is only supported in GUI mode.

You can also perform single file restore (SFR) via the SEP sesam GUI or the web Restore Assistant. Single file restore is only supported in UI mode where all options are available, i.e. in the Expert UI mode if you perform single file restore via the GUI, or in Advanced UI mode when you use the web Restore Assistant. For details on switching the UI mode, see Setting the UI mode in the GUI and Setting the UI mode in the Restore Assistant.

Limitation

Only VMs with SCSI disks can be restored from backup; restore is currently not supported for SATA, PCI and IDE disks.

Restoring a Nutanix AHV virtual machine

Depending on the interface you are using, follow the appropriate procedure to restore a Nutanix VM:

Typically, you would restore a VM to its original location (Restore to original VM) if the original VM is unusable. By restoring a full VM backup, you create a new VM with the identical content and configuration as when the backup was made. You can also restore your VM under a new name or to a different location.

VM restore via the GUI

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 filename or path.
    • When searching by task name, use the drop-down list of available tasks and select the one you want to restore. This option is enabled by default.
    • If you are searching by filename/path, select the option Filename or path in a saveset and enter your search expression in the search pattern field.
  3. Under Saved in period, select the time frame for which you want to perform the search from the drop-down lists. Click Next.
  4. The search results are displayed. From the list of savesets that match your search query, select the task you want to restore. The restore types Complete restore of selected task and Generation restore are selected by default and cannot be deselected. Click Next.
  5. Nutanix restore select task Jaglion.jpg

  6. In the Target Settings dialog box, check the configuration of your restore task and set additional options as needed.
  7. The name of the restore task is automatically generated in the Restore task name field. You can edit the name and add a comment below it.

    Target data
    You can restore the Nutanix AHV VM to the original VM (if the Target node is the same server from which the data was backed up, i.e., the source and target server are the same) or under a new VM name.
    If you want to restore the VM under a different name, select the option Restore with new VM name and enter a new VM name or use the Browser button to select a new target location; then select Create new version under the VM restore options.
    Target node
    It shows the target server where the data will be restored. By clicking Change VM target selection, you can restore a task to a different target (location) by selecting the appropriate target node and data store from the drop-down lists. In the case of Nutanix, the data store is a Nutanix storage container. If no target path is defined, the VM is restored to the default (original) location.
    VM restore options
    Select one of the following from the drop-down list:
    • Do not overwrite existing items (default): The VM will not be restored if a VM with the same name already exists on the target server. In this case, the following error is displayed: Error: Restore failed. A virtual machine with the same name already exists.
    • Overwrite existing items: If a VM with the same name exists on the target server, it will be replaced with the restored version. Note that if two VMs with the same name exist on the target server, the restore fails with: Error: Restore failed. A virtual machine with the same name already exists.
    • Create a new version: Restore the VM under a new name.
    • You can also select whether the VM should be started automatically after the restore by selecting Start virtual machine after restore/Do not start (selected by default).
    Optional data source selection
    • Preferred media pool: If the data was migrated or replicated and different media pools were used for the process, the source media pool to restore from can be selected from the drop-down list of available media pools.
    • Used media | barcode: If the data was migrated, the migrated copy is stored on a different media; the source media to restore from can be selected from the drop-down list of available media.
    • The Drive field shows the drive with the backed up data.
    • The Interface field displays the server with the attached data storage that contains the selected saveset.
    Expert options
    Clicking the Expert Options button (available only in Expert UI mode) allows you to specify additional options for the restore, such as changing the log level settings, define the pre/post script for the restore, etc. For details, see Restore Overview.
