How to Backup an Instance and Download it to the Desktop OpenStack Hosting

First, you will need to setup the OpenStack CLI environment on the computer to which you want to download your instance. Depending on the operating system you are using, follow one of the following links:

How to install OpenStackClient for Linux

How to install OpenStackClient GitBash for Windows

Assume that you are

logged into your Destination Earth hosting account with Horizon interface https://cloud.central.data.destination-earth.eu and that

you have created an instance called vm-john-01.

List Instances in Your Project

List instances in your project using the following CLI command:

user@ubuntu:~$ openstack server list

This will be the result:

ID	Name	Status	Networks	Image	Flavor
72170eb7-cee4-41a3-beea-c7d208446130	vm-john-01	ACTIVE	test_network=192.168.2.172, 64.225.128.53	Ubuntu 20.04 LTS	eo1.medium

Create a Backup

Now you can create a backup from command line interface (CLI) in the terminal (replace 72170eb7-cee4-41a3-beea-c7d208446130 with the ID of your instance):

user@ubuntu:~$ openstack server backup create --name backup-01 72170eb7-cee4-41a3-beea-c7d208446130

You can also add the –rotate<count> parameter to the above command if you want to have control over the number of stored backups:

user@ubuntu:~$ openstack server backup create --name backup-01 --rotate 2 72170eb7-cee4-41a3-beea-c7d208446130

You can see the backup backup-01 in

https://cloud.central.data.destination-earth.eu/project/images

https://cloud.lumi.data.destination-earth.eu/project/images

or with CLI command:

user@ubuntu:~$ openstack image list --private

The result would be:

+--------------------------------------+-----------+--------+
| ID                                   | Name      | Status |
+--------------------------------------+-----------+--------+
| 747d720d-a6f4-4554-bf56-16183e5fb7fa | backup-01 | active |
+--------------------------------------+-----------+--------+

Download the Backup File

Disk image is a raw copy of the hard drive of your virtual machine. You can download it using the following command (replace 72170eb7-cee4-41a3-beea-c7d208446130 with the ID of your disk image):

user@ubuntu:~$ openstack image save --file backup-on-the-desktop 747d720d-a6f4-4554-bf56-16183e5fb7fa

Upload the Backed Up File

After that, you can upload backup of your file using the Horizon dashboard:

Go to Project → Compute → Images.

Click on “Create Image”.

On this panel you must insert image name, choose backup file and backup format. Next click on “Create Image”.

You can also use CLI commands to upload the backup file:

user@ubuntu:~$ openstack image create --file path/to/backup <backup_name>
