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 virtual machines (VMs) is quite similar to a regular file system restore. There are two ways to restore your Nutanix virtual machines (VMs) in SEP sesam: by using GUI restore wizard (described below) or through the web interface Restore Assistant. Even though most of the options are the same in both restore interfaces, the web Restore Assistant interface is designed to be more intuitive and offers additional advanced options. However, it cannot be used for scheduling restore or single file restore as these are only supported in the GUI mode. For details, see Restore Assistant.

In the SEP sesam GUI, restore is triggered from the Menu bar -> Activities -> Restore. The restore wizard guides you through the process of restoring your data. Note that currently only the complete VM restore is supported. For the general restore procedure, see Standard Restore Procedure.

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

Typically, you should restore a virtual machine 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 it was when the backup was performed. You can also restore your VM with a new name or to a different location.

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, review your restore task configuration 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 to which 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, but its MAC address will remain the same. 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 to automatically start the virtual machine after 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 restore, etc. For details, see Restore Overview.

  8. In the last step of the restore wizard, you can review all the settings of your restore task. You can also edit the settings by using the Change Selection button. If you want to start your restore immediately, click Start. If you want to save the restore task, click Save.
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.

Monitoring restore

You can monitor the restore progress using the Web UI (Monitoring -> Restores) or view the status in the GUI (Main Selection -> Job State -> Restores). The restore overview provides detailed information on the last run of restore jobs, including task name, status (successful, error, in queue ...), start and stop time of the last backup, data size, throughput, etc. For details, see SEP sesam Web UI or Restores by State in the GUI.
