Abstract: Targetless snapshot schedules are defined by policy objects that include a snap creation interval, maximum snap count, and schedule ID. Multiple schedule IDs can be associated with a single storage object to implement different concurrent targetless snapshot schedules with a single storage object. Multiple storage objects may use the same targetless snapshot schedule independently. Because the targetless snapshot schedules are implemented independently, discard of old snapshots to maintain a snap count for a first storage object does not cause discard of snapshots for a second storage object. Further, discard of old snapshots to maintain a snap count for a first schedule does not cause discard of snapshots for a second schedule applied to the same storage object.

Abstract: Targetless snapshots that are in use are excluded from discard and exempted from inclusion against a snapshot retention count limit. Snapshots that are linked to a target volume are considered to be in use. Snapshots having a persist attribute set are considered to be in use. Snapshots having an expiration attribute set are considered to be in use until at least the expiration time. Snapshots having an age limit attribute set are considered to be in use until reaching at least the specified age. The snapshot retention count limit can be updated with a command. Other commands discard snapshots created before a specified time or older than a specified age, provided the snapshots are not in use. A terminate all command prompts discard of all snapshots that are not in use.

Abstract: In a medical image generation method, projection data of a scanned object is acquired during rotation of a radiographic source, and a scout image of the scanned object is generated in one scanning direction using corresponding projection data in two opposite scanning directions in the projection data. The scanning direction is used to represent a relative position relationship between the radiographic source and the scanned object. Using projection data in two opposite directions to generate a scout image in one direction during rotary scanning of a radiographic source can significantly shorten the generation time of the scout image.
