Managing Volume Snapshots in Arcus
The first step for the following document is to login to the Arcus interface with an Administrator or User level account.
You will be able to take snapshots of individual volumes or snapshots of all volumes attached to a single server.
Creating a Whole Server Snapshot
- Browse to the VM you want to take a snapshot of, click on the Menu button for the VM
- Select the "Snapshot" menu item, and then click "Create Snapshot" button on the pop-up confirmation window
- This will now trigger a snapshot to be created for all volumes attached to the server
Creating a Single Volume Snapshot
Attached to a VM
- Browse to the VM with the volume attached you want to take a snapshot of, click on the VM's card logo
- In the pop-up window, click on the Volumes/Snapshots tab.
- Find the Volume you want to snapshot, look to the right and click the Camera icon to take a snapshot
From the Volumes Page
- Browse to the Volumes page for the project with the VM in it from the main menu
- Find the Volume in the list you want to take a snapshot of and click the "Snapshot" button to the right of the volume
Deleting a Snapshot
To delete a snapshot, you can use any of the methods listed above to create the snapshot but you should see the snapshots listed below which can be deleted by clicking the Red "X" icon.
1. From the Volumes Page:
2. From the VM Volumes card:
Restoring a Snapshot
To restore a snapshot to a volume you must use the Openstack CLI, you can also turn a snapshot into a volume and build a new VM or attach the volume to the existing VM to recover files.
Navigate to the Volume Menu for the project that the snapshot exists in, select the "+" button in the bottom right hand corner. In the pop-up window select from the Volume Source dropdown list "Copy from snapshot", select the snapshot you want to use in the Source Snapshot dropdown list, create a unique name and click the Create Volume button.
