Restoring Full Instances for OpenStack

Updated

You can restore instances or images to the original location or to a different location. By default, an instance is restored to the original hypervisor, using the same proxy as the backup.

Consider the following information:

  • If the OS disk was filtered from the backup of an instance, the base image that the instance was based on must be available for the instance to be restored.

  • If an instance or image is added to VM group content or to a filter by browsing and selecting the display name, discovery is performed based on the GUID for the instance or image. If that instance or image is later restored in place from a backup, a new GUID is generated, and that instance or image is no longer identified correctly. To identify that instance or image, you must remove the old rule, then add a new rule or use a name pattern to select the instance or image.

  • If the user specified for the virtualization client does not have permission to create or delete network ports, the restore fails with error "Failed to create port with request".

  • When restoring public images for a project, the user performing the restore should have the Admin role for that project. When a user only has the Member role for a project, that user does not have permission to create public images and can only restore an image as a private image. In that situation, an Admin user could later make the restored image public.

Before You Begin

Procedure

  1. From the navigation pane, go to Protect > Virtualization.

    The Virtual machines page appears.

  2. On the Hypervisors tab, click the hypervisor.

    The hypervisor page appears. The VM groups area displays summary information for any existing VM groups.

  3. On the VM groups tab, in the row for the VM group, click the action button , and then click Restore.

    The Select restore type page appears.

  4. Select Full instance to restore a full instance.

    The Restore page appears.

  5. To choose a different MediaAgent or source copy for the restore, do the following:

    1. In the upper-right corner of the page, click Settings.

      The Settings dialog box appears.

    2. Configure the following options:

      • MediaAgent: Allow the Commvault software to select a MediaAgent or specify a MediaAgent:

        - Automatic: By default, the Commvault software selects the MediaAgent for the restore operation based on availability and environment.

        - To restore data using a specific MediaAgent, from the list, select a MediaAgent.

      • Source: Allow the Commvault software to select the copy of backup data or specify the copy:

        - Automatic: By default, the restore operation searches for the requested data in the primary copy and selects a different copy if the data is not found in the primary copy.

        - To restore from a specific copy of backup data, from the list, select a backup copy.

    3. Click Save.

  6. In the left pane, expand the list, and then in the right pane, select the objects you want to restore:

    • To browse the contents inside an item, under Name, click the item.

    • To return to a higher level of the hierarchy, for data such as files, folders, and disks, above the right pane, in the path list, click an item.

    • In the upper-right area of the page, a message indicates which backup data is displayed. Click the down arrow, and then select any of the following options:

      • Show latest backups: Display data only for the most recent backups.

      • Show backups as of a specific date: Display data only up to the date you specify.

      • Show backups for a date range: Display data only within the date range you specify.

  7. Click Restore.

    The Restore options dialog box appears.

  8. Provide the requested information:

    • Access node: (Optional) By default, the preferred VSA proxy for the hypervisor is used for the restore. You can select a different proxy from the list.

    • Destination: To restore to a hypervisor, select the virtualization client for the cluster from the list.

    • If you are restoring multiple instances, click the All Instances tab on the bottom left to specify configuration values for all instances you are restoring, or the name of each instance to specify values individually. Specify the following values:

      • Instance name: (Optional) To change the name of an individual instance, select the instance and then enter the new display name in the box.

        If an existing instance with the same name exists on the destination host and you do not select Unconditionally overwrite if it already exists, the restore job fails.

      • Enable edit destination instance name: (Optional) When restoring multiple instances, to change the names of destination instances, select this option, select Prefix or Suffix, and then enter a string to be appended to the original display name to create new destination instance names.

      • Availability zone: Browse the defined availability zones and select a host.

      • Volume type: Select a volume type that is defined for the zone of the source volumes.

      • Flavor: Select a flavor that is at or above the original configuration.

      • Security group: Select a predefined security group that defines the required network access.

      • Key pair: Select a key pair that identifies the ownership for the converted instance.

      • Network interface: Select a network interface that is available in the destination.

    • Power on instances after restore: (Optional) Start the instance automatically when the restore completes.

    • Unconditionally overwrite if it already exists: (Optional) Delete an existing instance that has the same name, and replace it with the restored instance.

  9. Click Submit to run the restore job.
