Abstract

Methods, systems and software components are described for exporting media in a library according to a schedule. At a first time, a user provides and a system receives export identification data including data identifying one or more media from the library to be exported and data identifying a second time at which the one or more media is scheduled to be exported. The first data may be a list of media identified by media identifiers and related data or may be a set of one or more criteria which are evaluated to determine which media in the library should be exported at the scheduled time. The export identification data is stored in a relational database table. At the second, scheduled time, the stored export identification data is used to select the one or more media to be exported to export the selected media from the library.

Claims

1. A method for exporting media in a library according to a schedule, comprising:

at a first time, receiving export identification data comprising first data identifying one or more media from the library to be exported and second data identifying a second time at which the one or more media is scheduled to be exported;

storing the export identification data in a data file; and

at the second time, using the stored export identification data to select the one or more media to be exported to export the selected media from the library.

2. The method of claim 1, wherein receiving export identification data comprises receiving a list of one or more media.

4. The method of claim 1, wherein receiving export identification data comprises receiving one or more media selection criteria.

5. The method of claim 4, wherein using the stored export identification data to select the one or more media to be exported comprises evaluating the stored media selection criteria to determine which of the media in the library meets the one or more media selection criteria.

6. The method of claim 4, wherein receiving one or more media selection criteria comprises receiving a criteria defined by a length of time since a media was last read from or written to.

7. The method of claim 1, wherein storing the export identification data comprises storing the export identification data in an administrative task parameter table.

8. The method of claim 7, comprising accessing the administrative task parameter table at the second time to retrieve the identification data.

9. The method of claim 1, comprising storing an export history table containing a plurality of fields identifying the media to be exported and a status of the export of each such media.

10. The method of claim 8, comprising updating the export history table following an attempt to export the media from the library.

11. The method of claim 1, comprising receiving an instruction to halt or delay an export and halting or delaying the export.

3. The method of claim 3, wherein receiving a list of one or more media comprises receiving a list of media identifiers.

12. An administrative system for scheduling an export of one or more media from a library, the system comprising:

a user interface for receiving, at a first time, export identification data comprising first data identifying one or more media from the library to be exported and second data identifying a second time at which the identified one or more media is scheduled to be exported;

a data file stored in a memory device for storing the export identification data; and

a task control subsystem for retrieving the export identification data at the second time from the data file and controlling the library to cause the export of the media identified by the media identification data.

13. The system of claim 12, wherein the user interface is configured to allow a user to specify one or more media to be exported by one or more respective media identifiers, the data file storing the specified media identifiers.

14. The system of claim 12, wherein the user interface is configured to allow a user to specify one or more criteria by which media is selected to be exported, the database storing the specified one or more criteria.

15. The system of claim 14, wherein the task control subsystem comprises an evaluator for evaluating the stored criteria to determine which one or more media in the library satisfy the specified one or more criteria at the second time.

16. The system of claim 12, comprising an export history data file stored in a memory device, the export history data file containing a field associated with each media indicating a status of the export of the media.

17. The system of claim 12, wherein the user interface is configured to allow a user to specify second data comprising a specified event following which the media is to be exported.

18. A data structure stored on a computer readable medium comprising first data identifying one or more media from a media library and second data identifying a time at which the identified one or more media are scheduled to be exported from the library, the data structure being accessed by a task control application program at the second time to determine which one or more media are scheduled to be exported at the second time and to send a control signal to the media library to initiate export of the identified one or more media.

19. The data structure of claim 18, wherein the first data comprises a list of one or more media identifiers.

20. The data structure of claim 19, wherein the first data comprises one or more criteria by which one or more media is selected to be exported at the second time.
