How to create instance snapshot using Horizon on 3Engines Cloud[🔗](#how-to-create-instance-snapshot-using-horizon-on-brand-name "Permalink to this headline")
|
|
===============================================================================================================================================================
|
|
|
|
In this article, you will learn how to create instance snapshot on 3Engines Cloud cloud, using Horizon dashboard.
|
|
|
|
Instance snapshots allow you to archive the state of the virtual machine. You can, then, use them for
|
|
|
|
> * backup,
|
|
> * migration between clouds
|
|
> * disaster recovery and/or
|
|
> * cloning environments for testing or development.
|
|
|
|
We cover both types of storage for instances, *ephemeral* and *persistent*.
|
|
|
|
The plan[🔗](#the-plan "Permalink to this headline")
|
|
---------------------------------------------------
|
|
|
|
In reality, you will be using the procedures described in this article with the already existing instances.
|
|
|
|
However, to get a clear grasp of the process, while following this article you are going to create two new instances, one with *ephemeral* and the other with *persistent* type of storage. Let their names be **instance-which-uses-ephemeral** and **instance-which-uses-volume**. You will create an instance snapshot for each of them.
|
|
|
|
If you are only interested in one of these types of instances, you can follow its respective section of this text.
|
|
|
|
It goes without saying that after following a section about one type of virtual machine you can clean up the resources you created to, say, save costs.
|
|
|
|
Or you can keep them and use them to create an instance out of it using one of articles mentioned in What To Do Next.

|
|
|
No. 3 **Instance with ephemeral storage**
|
|
|
|
You need a virtual machine hosted on 3Engines Cloud cloud.
|
|
|
|
Using any of the following articles will produce an instance with ephemeral storage: |
