This article will walk you through configuring snapshot images on your Cloud Server. Rackspace Cloud Servers include both Scheduled and On-Demand snapshots. This is an optional service that will incur storage and bandwidth charges on Cloud Files, but the convenience of easily restoring from saved images is extremely valuable. Enabling scheduled imaging is quick and easy.
4. Now click on the Images tab. In order to enable regularly scheduled snapshots that run automatically for your server, press the button to Enable Scheduled Imaging.
5. Once enabled, you have the ability to schedule your snapshots to occur within a 2 hour window on a daily basis, as well as the day for a separate weekly image to be run. Once set, press the Save Schedule button to activate Scheduled Imaging. Your images will be saved in Cloud Files and will incur a monthly storage charge, plus bandwidth charges when the image file is accessed. If you do not wish to use Scheduled Imaging, press the Disable button.
6. In addition to a scheduled image, you can create an On-Demand image at any time. Press the New On-Demand Image button. Create a unique name for the image, and click Finish. You can store an unlimited amount of On-Demand images on Cloud Files.
7. Your On-Demand image will now be queued, and will run as soon as resources are available.
8. When your On-Demand image is ready the Status will change to available. Clicking the check box to the right of an available On-Demand image will enable two different actions. You can use this image to restore your server - this means wiping all data and replacing it with this image. Or, you can also choose to Delete the On-Demand image.
Note: Scheduled snapshots can be valuable tools but should not be considered a comprehensive backup solution. Snapshots are taken while the server and its processes are active, meaning that a database might be writing data or files might be saving at the time of the snapshot. That can lead to some data corruption within the image.
In particular, we recommend backing up databases with their own backup tool (like mysqldump) and copying the backup file elsewhere for the purposes of disaster recovery.
In the next article we will show you how easy it is to restore your server using a saved image.
