If you select an image that\n belong to any of the types listed, you may not see the\n **Manage Expiration** option. You cannot expire images that are of type:\n\n - failover\n - prep-mount\n - streamsnap\n - syncback\n - liveclone\n- Images that use the **Enforced Retention** advanced policy setting to set\n an immutability date to a later date cannot be configured for expiration\n before the specified immutability period is over.\n\n | **Note:** The enforced retention advanced policy setting is not compatible with application protection that points to a backup vault. When a backup vault is the storage target, the backup vault determines the enforced retention period.\n\nFor more information on immutability and enforced retention, see\n[Configuring Advanced Settings: Policy Settings Override](/backup-disaster-recovery/docs/create-plan/policy-settings).\n\nManaging image expiration in the applications page\n--------------------------------------------------\n\nUse the following instructions to manage image expiration for all images in an\napplication:\n\n1. Click the **App Manager** tab and select **Applications** from the drop-down menu.\n2. Right-click the application that has the images you want to expire and select **Manage Expiration**.\n3. 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.\n4. 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.\n5. Select from the following expiration options:\n\n - **Expire all images now**: When the scheduler runs next, expiration jobs start for these images.\n - **Set new expiration date**: lets you select a new expiration date and time.\n - **Extend retention by**: lets you extend the expiration by the number of days or weeks or months or years you specify.\n - **Shorten retention by**: lets you shorten the expiration by the number of days or weeks or months or years you specify.\n - **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](/backup-disaster-recovery/docs/access-data/access-image-copy-data-list).\n6. Click **Apply**.\n\nManage image expiration from table view\n---------------------------------------\n\nUse the following instructions to manage image expiration of one or more images\nfrom the table view:\n\n1. Click the **App Manager** tab and select **Applications** from the drop-down menu. The **Applications** page opens.\n2. Right-click the application that has the image(s) you want to expire and select **Access** . The **Timeline** view opens.\n3. Select the **Table** option. The **Images** page opens listing captured\n images in the table view.\n\n4. Click one or more images, and then select **Manage Expiration** from the\n lower right corner of the page. Alternately, right-click the application and\n select **Manage Expiration** . The **Manage Expirations** dialog opens.\n\n5. Select from the following expiration options:\n\n - **Expire Now**: when the scheduler runs next, expiration jobs start for these images.\n - **Set new expiration date**: lets you select a new expiration date and time.\n - **Extend retention by**: (default option) lets you extend the expiration by the number of days, weeks, months, or years you specify.\n - **Shorten retention by**: lets you shorten the expiration by the number of days, weeks, months, or years you specify.\n\n When specifying a shortened retention period, the new expiration date\n for some images may actually be a date in the past. In this situation,\n the dialog will list all images that will have an expiration date set\n in the past along with a warning that these images will expire immediately.\n - **Set to never expire** : configures 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 the [Accessing Copy Data List View of an Image](/backup-disaster-recovery/docs/access-data/access-image-copy-data-list).\n6. Select one of the following **Log retention** options. This option displays\n only when the selected backup image has associated logs.\n\n - **Do not change log retention**: select this option if you don't want to change log retention period. By default, this option is selected.\n - **Linked to database image**: select this option to retain database logs until the database image expires and the logs are past the configured log retention period.\n - **Independent from database image**: select this option to retain all database logs for the selected database images, regardless of when they expire.\n7. Click **Apply**.\n\nManage image expiration in the timeline view of the access page\n---------------------------------------------------------------\n\nUse the following instructions to manage expiration of a specific image from\nthe timeline ramp view:\n\n1. Click the **App Manager** tab and select **Applications** from the drop-down menu. The **Applications** page opens.\n2. Right-click the application that has the image(s) you want to expire and select **Access** . The **Access** page opens listing captured images in the **Timeline** view.\n3. Select the image you want to manage expiration for, then select\n **Manage Expiration** from the menu options. The **Manage Expiration** page opens.\n\n4. Select from the following expiration options:\n\n - **Expire images now**: forces the expiration job to run at that time and expire the image.\n - **Set new expiration date**: lets you select a new expiration date and time.\n - **Extend retention by**: (default option) lets you extend the expiration by the number of days or weeks or months or years you specify.\n - **Shorten retention by**: lets you shorten the expiration by the number of days or weeks or months or years you specify.\n - **Set 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](/backup-disaster-recovery/docs/access-data/access-image-copy-data-list).\n - **Do not change expiration date**: Select this option if you don't want to change the expiration date for a backup image of a database. This option is displayed only when the selected backup image has associated database logs.\n5. Select one of the following **Log retention** options. This option displays only when the selected backup image has associated logs.\n\n - **Independent from database image** (default): select this option to retain all database logs for the selected database images, regardless of when they expire.\n - **Linked to database image**: select this option to retain database logs until the database image expires and the logs are past the configured log retention period. If a dependency between the image and its log images has been established, this option is selected by default.\n6. Click **Apply**.\n\nForce expiration of an active image\n-----------------------------------\n\nTo force the expiration of an active image:\n\n1. Click the **App Manager** tab and select **Applications** from the drop-down menu. The Applications page opens.\n2. Select the application or VM that contains the captured image that you want to expire, then choose **Access** from the drop-down list at the bottom right corner of the Applications page. The Access page opens listing captured images in the Timeline ramp view. Image types that support expiration include Snapshot, Remote Snapshot (StreamSnap images), and OnVault. For more information about the Timeline view, see [Accessing the Timeline View of an Image](/backup-disaster-recovery/docs/access-data/access-image-copy-data-list#access-time) for details.\n3. Select the image that you want to expire, then select **Expire** from the drop-down list. The Expire page opens.\n4. Click **Submit** to expire the image."]]
