In CloudRanger, there are three ways to restore a snapshot. You can leave the volume unattached, you can attach the volume to the instance, or you can request a file level restore.
When you are viewing your list of backups via the backups resource section, you will have the ability to click the "RESTORE" option for each snapshot listed.
Here you will be presented with an overview of the snapshot you are going to restore, with associated tags. Three restore options will be available and you may choose whichever method is best for you.
