The LTSM Auto Delete process cleans the LTSM cache either periodically or on demand. It removes all the fetched studies from the RIS file system that have resided in the cache longer than the preconfigured time.
The LTSM Auto Delete process is triggered by a prescheduled timing schedule when the available free online space reaches a user-defined red zone threshold. The LTSM Auto Delete process cleans the RIS cache until its free space reaches a user-defined green zone threshold. Studies can only be deleted after they are backed up onto tape.
