You can use Amazon S3 object versioning and lifecycle policies to manage your users’ application settings when your users change them. With Amazon S3 object versioning, you can preserve, retrieve, and restore every version of the settings VHD. This enables you to recover from both unintended user actions and application failures. When versioning is enabled, after each streaming session, a new version of the application settings VHD is synced to Amazon S3. The new version does not overwrite the previous version, so if an issue with your users' settings occurs, you can revert to a previous version of the VHD.
Note
Each version of the application settings VHD is saved to Amazon S3 as a separate object and is charged accordingly.
Object versioning is not enabled by default in your S3 bucket, so you must explicitly enable it.
To enable object versioning for your application settings VHD
Open the Amazon S3 console at https://console.aws.amazon.com/s3/
. -
In the Bucket name list, choose the S3 bucket that contains the application settings VHD on which to enable object versioning.
-
Choose Properties.
-
Choose Versioning, Enable versioning, and then choose Save.
To expire older versions of your application settings VHDs, you can use Amazon S3 lifecycle policies. For information, see How Do I Create a Lifecycle Policy for an S3 Bucket? in the Amazon Simple Storage Service User Guide.
To revert a user's application settings VHD
You can revert to a previous version of a user's application settings VHD by deleting newer versions of the VHD from the applicable S3 bucket. Do not do this when the user has an active streaming session.
Open the Amazon S3 console at https://console.aws.amazon.com/s3/
. -
In the Bucket name list, choose the S3 bucket that contains the user's application settings VHD version to revert to.
-
Locate and select the folder that contains the VHD. For information about how to navigate the S3 bucket folder structure, see Amazon S3 Bucket Storage earlier in this topic.
When you select the folder, the settings VHD and associated metadata file display.
-
To display a list of the VHD and metadata file versions, choose Show.
-
Locate the version of the VHD to revert to.
-
In the Name list, select the check boxes next to the newer versions of the VHD and associated metadata files, choose More, and then choose Delete.
-
Verify that the application settings VHD that you want to revert to and the associated metadata file are the newest versions of these files.
The next time the user streams from a fleet on which application settings persistence is enabled with the applicable settings group, the reverted version of the user's settings displays.
