Abstract

Systems and methods are disclosed for editing metadata for data objects on a data storage device, which may be configured to identify data objects that have been modified and may be associated with storage locations of a file system. The data storage device may also be configured determine whether a first period of time has elapsed and may further be configured to determine whether a second period of time has elapsed or whether a threshold number of data objects in the file system have been modified in response to a first determination that the first time period has elapsed. The data storage device may further be configured to edit a set of metadata for a set of data objects in response to a second determination that the second period of time has elapsed or the threshold number of data objects in the file system have been modified.

Claims

1. A method, comprising:

identifying one or more data objects that have been modified, wherein the one or more data objects are stored at one or more storage locations of a file system of a data storage device; and

batching edits to metadata for the one or more data objects by;

determining whether a first period of time has elapsed;

in response to a first determination that the first period of time has elapsed, determining whether a second period of time has elapsed or whether a threshold number of data objects in the file system have been modified;

in response to a second determination that the second period of time has elapsed or that the threshold number of data objects in the file system have been modified, editing a set of metadata for a set of data objects, wherein;

the set of data objects comprises the one or more data objects;

the set of metadata is stored on the data storage device; and

editing the set of metadata comprises updating existing metadata for an existing file or an existing folder; and

in response to a third determination that the second period of time has not elapsed and that the threshold number of data objects have not been modified, refraining from editing the set of metadata.

2. The method of claim 1, wherein identifying the one or more data objects comprises:

determining whether a queue of storage locations comprises a first storage location associated with a first data object that has been modified; and

in response to determining that the first storage location is not included in the queue of storage locations, adding the first storage location to the queue of storage locations.

3. The method of claim 2, further comprising:

determining whether a number of data objects that have been modified has increased.

4. The method of claim 3, wherein determining whether the second period of time has elapsed or whether the threshold number of data objects in the file system have been modified is further in response to a fourth determination that the number of data objects that have been modified has increased.

5. The method of claim 2, wherein editing the set of metadata further comprises:

one or more of adding or deleting metadata for the set of data objects; and

removing a set of storage locations from the queue of storage locations.

6. The method of claim 1, wherein the one or more storage locations comprise folders in the file system.

7. The method of claim 1, wherein the set of metadata comprises one or more of a name, an author, a title, a location, a timestamp, a resolution, or a size.

8. The method of claim 1, wherein a data object has been modified when the data object has been added, deleted, updated, renamed, or moved.

9. The method of claim 1, wherein the one or more data objects comprise one or more of a file or a folder.

10. The method of claim 1, wherein the second period of time is greater than the first period of time.

11. A network-attached storage (NAS) device comprising:

a memory configured to store data objects; and

a processor, coupled to the memory, the processor configured to;

identify one or more data objects that have been modified, wherein the one or more data objects are stored at one or more storage locations of a file system of the NAS device; and

batch edits to metadata for the one or more data objects by;

determining whether a first period of time has elapsed;

in response to a first determination that the first period of time has elapsed, determining whether a second period of time has elapsed or whether a threshold number of data objects in the file system have been modified;

in response to a second determination that the second period of time has elapsed or that the threshold number of data objects in the file system have been modified, editing a set of metadata for a set of data objects, wherein;

the set of data objects comprises the one or more data objects;

the set of metadata is stored on the NAS device; and

editing the set of metadata comprises updating existing metadata for an existing file or an existing folder; and

in response to a third determination that the second period of time has not elapsed and the threshold number of data objects have not been modified, refraining from editing the set of metadata.

12. The NAS device of claim 11, wherein the processor is configured to identify the one or more data objects by:

determining whether a queue of storage locations comprises a first storage location associated with a first data object that has been modified; and

in response to determining that the first storage location is not included in the queue of storage locations, adding the first storage location to the queue of storage locations.

13. The NAS device of claim 12, wherein the processor is further configured to:

determine whether a number of data objects that have been modified has increased.

14. The NAS device of claim 13, wherein the processor is configured to determine whether the second period of time has elapsed or whether the threshold number of data objects in the file system have been modified further in response to a fourth determination that the number of data objects that have been modified has increased.

15. The NAS device of claim 12, wherein the processor is further configured to edit the set of metadata by:

one or more of adding or deleting metadata for the set of data objects; and

removing a set of storage locations from the queue of storage locations.

16. The NAS device of claim 11, wherein the one or more storage locations comprise folders in the file system.

17. The NAS device of claim 11, wherein the set of metadata comprises one or more of a name, an author, a title, a location, a timestamp, a resolution, or a size.

18. The NAS device of claim 11, wherein a data object has been modified when the data object has been added, deleted, updated, renamed, or moved.

19. The NAS device of claim 11, wherein the one or more data objects comprise one or more of a file or a folder.

20. The NAS device of claim 11, wherein the second period of time is greater than the first period of time.
