Snapshots

Snapshots can be taken of a specific volume or a VM instance which can include a boot volume and multiple data volumes. The snapshot takes a copy of the volume or a VM instance at a specific time, and then subsequent snapshots create a change log thus allowing for restoration of a single volume or an entire VM instance. Volume snapshots can also be used to create images.

Creating Snapshots of VM Instances

1. Navigate to the Compute > Instances view.

2. From the displayed list, select the VM instance for which the snapshot is to be created and click More.

3. In the More menu, select Snapshot.

4. In the displayed Create Snapshot window, enter a name for the new snapshot or accept the default name consisting of the original VM instance name and the date-time stamp of the snapshot creation.

5. Enter the description of the snapshot.

6. Click OK. A new snapshot is created. It is displayed in the Compute > Snapshots view.

Recover VM Instances from Snapshots

1. Navigate to the Compute > Snapshots view.

2. From the displayed list, select a VM instance snapshot.

3. From the top toolbar, click Restore.

4. In the Restore Instance > Basic tab, enter the following:

   • Name - the display name for the VM instance.

   • Instance Type - defines the amount of compute resource of the VM instance (CPU and RAM).

   • Network Settings - select from the following 3 options:

     • Same Network + IP - recovered VM instance will have same IP as that in the snapshot.

     • Same Network - recovered VM instance will be on same network as that in snapshot but with different IP.

     • Manual - select any network.

   • Storage Pool - storage pool that will be used for the boot volume of the VM instance.

   • Power Up - launches the VM instance post creation.

5. In the Restore Instance > Advanced tab, enter the following:

   • Boot Volume - size of boot volume in GB.

   • Profile - select from the following 3 options:

     • Reserved - the VM’s provisioned memory and CPU are always available. This profile is recommended for performance critical tasks.

     • On Demand - most of the VM’s provisioned memory and a minimal amount of CPU are always available. The rest will be allocated on-demand if there are available non-reserved resources. This profile is the default recommendation for standard tasks.

     • Spot - only a minimal amount of the VM’s provisioned memory and CPU are always available. The rest will be allocated on-demand if there are available non-reserved resources. This profile is recommended for non-critical tasks.

   • Tags - attach one or more tags to this VM instance.

   • Key Pair - set of security credentials for ensuring the identity of the user connecting to the VM instance.

   • High Availability - check this option to ensure the instance is restarted in the event of a failure.

   • Protect from Deletion - check this option to protect the instance from accidental deletion.

6. Click Finish.
