Abstract

A system and method for determining media to be exported out of a media library is described. In some examples, the system determines a media component to be exported, determines the media component is in the media library for a specific process, and exports the media component after the process is completed.

Claims

1. A system for recalling data storage media components to a media library based on changes made to data in a file system, comprising:

a processor;

a data change component coupled to the processor, wherein the data change component provides information related to changes made to an original copy of a data set stored by a local file system,

wherein the local file system is associated with a data storage system that comprises a media library, and

wherein a physical media component that is located outside of the media library contains a second copy of the data set;

a data identification component that is configured to identify the physical media component that contains the second copy of the data set and that is located outside of the media library in response to being provided with the information related to the changes made to the original copy of the data set; and

a media recall component, in communication with the data change component and the data identification component, that is configured to automatically initiate a recall of the identified physical media component that contains the second copy of the data set to the media library in response to

(a) being provided with the information related to the changes made to the original copy of the data set and

(b) at a time when the original copy of the data set is still stored by the local file system; and

an action component, in communication with the data change component and the data identification component, wherein the action component performs an action based on the changes made to the original copy of the data set stored by the local file system using the recalled media component.

2. The system of claim 1, further comprising:

a restore component, in communication with the data change component and the data identification component, wherein the restore component performs a restore operation using the data contained in the recalled media component.

3. The system of claim 1, further comprising:

a restore component, in communication with the data change component and the data identification component, wherein the restore component holds the recalled media component within the media library for use in a restore operation and releases the media component from the media library after completion of the restore operation.

4. The system of claim 1, further comprising:

an update component configured to update metadata on the recalled media component to reflect some of the changes made to the original copy of the data set.

5. The system of claim 1, further comprising:

a restore component, in communication with the data change component and the data identification component, wherein the restore component holds the recalled media component within the media library for a pre-determined period of time and releases the media component from the media library after the pre-determined period of time.

16. The system of claim 1, wherein the changes made to the original copy of the data set comprise a change to a characteristic of the original copy of the data set, the changed characteristic being:

a use of the data set, an owner of the data set, a frequency of access to the data set, or a size of the data set.

6. A method implemented by at least one processor for recalling data storage media components to a media library based on changes made to data in a file system, comprising:

detecting information related to changes made to an original copy of a data set stored by a local file system,

wherein the local file system is associated with a data storage system that comprises a media library, and,

wherein a physical media component that is located outside of the media library contains a second copy of the data set;

identifying the physical media component that contains the second copy of the data set and that is located outside of the media library in response to being provided with the information related to the changes made to the original copy of the data set; and

in response to identifying the physical media component, automatically initiating a recall of the identified physical media component that contains the second copy of the data set to the media library in response to;

(a) being provided with the information related to the changes made to the original copy of the data set, and

(b) at a time when the original copy of the data set is still stored by the local file system; and

performing an action based on the changes made to the original copy of the data set stored by the local file system using the recalled media component.

7. The method of claim 6, further comprising:

performing a restore operation using the data contained in the recalled media component.

8. The method of claim 6, further comprising:

holding the recalled media component within the media library for use in a restore operation; and

,

releasing the media component from the media library after completion of the restore operation.

9. The method of claim 6, further comprising:

updating metadata on the recalled media component to reflect some of the changes made to the original copy of the data set.

10. The method of claim 6, further comprising:

holding the recalled media component within the media library for a pre-determined period of time; and

,

releasing the media component from the media library after the pre-determined period of time.

11. A tangible computer-readable medium having computer-executable instructions that, when executed by a computer, perform a method for recalling data storage media components to a media library based on changes made to data in a file system, the method comprising:

detecting information related to changes made to an original copy of a data set stored by a local file system,

wherein the local file system is associated with a data storage system that comprises a media library, and,

wherein a physical media component that is located outside of the media library contains a second copy of the data set;

identifying the physical media component that contains the second copy of the data set that is located outside of the media library in response to being provided with the information related to the changes made to the original copy of the data set; and

in response to identifying the physical media component, automatically initiating a recall of the identified physical media component that contains the second copy of the data set to the media library in response to;

(a) being provided with the information related to the changes made to the original copy of the data set, and

(b) at a time when the original copy of the data set is still stored by the local file system; and

performing an action based on the changes made to the original copy of the data set stored by the local file system using the recalled media component.

12. The computer-readable medium of claim 11, wherein the method further comprises:

performing a restore operation using the data contained in the recalled media component.

13. The computer-readable medium of claim 11, wherein the method further comprises:

holding the recalled media component within the media library for use in a restore operation; and

,

releasing the media component from the media library after completion of the restore operation.

14. The computer-readable medium of claim 11, wherein the method further comprises:

updating metadata on the recalled media component to reflect some of the changes made to the original copy of the data set.

15. The computer readable medium of claim 11, wherein the method further comprises:

holding the recalled media component within the media library for a pre-determined period of time; and

,

releasing the media component from the media library after the pre-determined period of time.
