The Delete Lightsail Instance Snapshots action can be used to delete many Lightsail snapshots based on specific criteria. Possible criteria includes the snapshot's name or instance's name.
For example, it can be used to:
delete all snapshots
delete all snapsnots older than 7 days
delete only snapshots that contain "backup" in it's name.
delete only snapshots that contain "prod" in it's instance's name.
delete snapshots that contain "backup" in it's name and are older than 5 days
The Delete Lightsail Instance Snapshots action includes a "test mode" as a way of determining which snapshots will be deleted without actually deleting the snapshots. This way, you can fine tune your action without concern for deleting the wrong snapshots. Test Mode is on by default.
When test mode is enabled, execute your action normally then check the action logs to verify that only snapshots that should have been deleted would have been deleted, and that snapshots that should not have been deleted would not have been deleted.
When you are satisfied, disable Test Mode.
Criteria acts as a filter. If no criteria is specified, all snapshots will be deleted.
Please see Common Action Settings for a description of settings common to all action types.
