How can I back up my instance?
When to take a snapshot
It is a good idea to create a backup after you create your instance and have loaded your software stack onto it. That way if something happens to your instance you don't have to re-create it from scratch. It is also a very good idea to create a snapshot if you are going to create a lot of running copies of the same image. Snapshots should NOT be used for regular backups. It is resource intensive and will make the Nebula operators grumpy at you.
