**Rotating backups** in OpenStack refer to a backup strategy where older backups are automatically deleted after a predefined number of backups are created. This ensures that storage does not grow indefinitely while still maintaining a set number of recent backups for disaster recovery.

backup create vs. image create[🔗](#backup-create-vs-image-create "Permalink to this headline")
----------------------------------------------------------------------------------------------

There are two ways of creating backups under OpenStack, using one of these two commands:

**openstack server backup create** and **openstack server image create**

Here is how they compare:

Table 4 Comparison of Backup and Image Creation Commands[🔗](#id1 "Permalink to this table")

| Feature | `openstack server backup create` | `openstack server image create` |
| --- | --- | --- |
| Association with VM | Associated using **backup** image property | Associated using backup name |
| Rotation support | Rotation with `--backup-type` and incremental backups | No built-in rotation support |
| Classification in Horizon | Marked as **image** | Marked as **snapshot** |
| Horizon **Select Boot Source** | Choose **Instance Snapshot** | Choose **Image** |
| Purpose | Primarily used for backups, can be rotated and managed | Creates a single VM snapshot without rotation |
| Multiple rotating schedules | No, only one | Yes (daily, weekly, monthly etc.) |
| Incremental backup support | Yes, supports incremental backups | No, always creates a full snapshot |
| Best usage scenario | Automated backup strategies with rotation | Capturing the current state of a VM for cloning or rollback |
| Can be scripted? | Yes | Yes |

In this article, you will learn how to create multiple series of rotating backups with a script which uses multiple **OpenStackClient** commands to achieve this goal.
