You can force the expiration of an image earlier than its scheduled date and time in order to gain storage space and potentially reduce storage costs.
You can manage image expiration in the following ways:
From the Application page to expire all images in an application.
From the Table view to expire one or more images in an application.
From the Timeline view to expire only the selected image.
Image expiration limitations
When you are configuring for image expiration, consider the following limitations:
Certain image types cannot be expired. If you select an image that belong to any of the types listed, you may not see the Manage Expiration option. You cannot expire images that are of type:
- failover
- prep-mount
- streamsnap
- syncback
- liveclone
Images that use the Enforced Retention advanced policy setting to set an immutability date to a later date cannot be configured for expiration before the specified immutability period is over.
For more information on immutability and enforced retention, see Configuring Advanced Settings: Policy Settings Override.
Managing image expiration in the applications page
Use the following instructions to manage image expiration for all images in an application:
- Click the App Manager tab and select Applications from the drop-down menu.
- Right-click the application that has the images you want to expire and select Manage Expiration.
- Optional. Disable the Enable Scheduled Expiration option. When you disable this option, images that would have expired based on the configured schedule can no longer expire.
- Optional: Disable the Enable Log Expiration option. When you disable this option, a database log data that would have expired based on the configured retention can no longer expire.
Select from the following expiration options:
- Expire all images now: When the scheduler runs next, expiration jobs start for these images.
- Set new expiration date: lets you select a new expiration date and time.
- Extend retention by: lets you extend the expiration by the number of days or weeks or months or years you specify.
- Shorten retention by: lets you shorten the expiration by the number of days or weeks or months or years you specify.
- Set all existing images to never expire: configure the images to never expire. By default, images that are set to never expire, will have an expiration date set to 2100-01-01. The Copy Data List view has an Expiration filter option Never that shows images configured to never expire. For information on the Copy Data List view, see Accessing Copy Data List View of an Image.
