Abstract

Systems and methods for managing data, such as metadata or index databases. In one exemplary method, a notification that an existing file has been modified or that a new file has been created is received by an indexing software component, which then, in response to the notification performs an indexing operation, where the notification is either not based solely on time or user input or the notification includes an identifier that identifies the file. Other methods in data processing systems and machine readable media are also described.

Claims

1. A machine implemented method of processing data, the method comprising:

mounting a storage device;

determining, by a data processing system automatically in response to the mounting, whether to index one or more files on the storage device, wherein the determining comprises

determining a first delay between a last time of usage or closing of an indexing database and an unmounting time or last write time of the storage device and also comprises

determining a second delay between a first time of usage or opening of the indexing database after the unmounting time and a mounting time or first write time of the storage device and also comprises

determining not to index the one or more files if the first delay is less than a first criteria and the second delay is less than a second criteria.

2. The method of claim 1 wherein the determining comprises evaluating whether files on the storage device have been modified since an indexing database for the files was last closed.

3. The method of claim 2 wherein the determining whether to index further comprises performing a time based comparison without examining a record for each file indexed in the indexing database.

4. The method of claim 1 wherein indexing is stalled or delayed in response to detecting user activity.

5. The method of claim 1 wherein a processing priority of indexing is reduced in response to detecting user activity.

6. A machine readable storage medium storing instructions which when executed by a data processing system cause the data processing system to perform a method of processing data, the method comprising:

mounting a storage device;

determining, automatically in response to the mounting, whether to index one or more files on the storage device, wherein the determining comprises

determining a first delay between a last time of usage or closing of an indexing database and an unmounting time or last write time of the storage device and also comprises

16. A machine implemented method of processing data, the method comprising:

mounting a storage device;

evaluating, by a data processing system after the mounting, whether to automatically index or update a metadata database for one or more files on the storage device by

evaluating whether files on the storage device have been modified or new files have been added since a database for the files on the storage device was last closed or written to and

determining a first delay between a first time of usage or opening of the metadata database after a time when the storage device was last closed and a mounting time or first write time of the storage device and

determining not to index or update the metadata database for the one or more files if the first delay is less than a first criteria.

17. The method of claim 16 wherein the evaluating comprises performing at least one time based comparison without examining a record for each file indexed or updated in the database.

18. The method of claim 17 wherein the evaluating further comprises a comparison of write counts.

19. The method of claim 16 wherein the storage device is a removable storage device which is portable among systems.

20. The method of claim 16 wherein indexing is stalled or delayed in response to detecting user activity.

21. The method of claim 16 wherein a processing priority of indexing is reduced in response to detecting user activity.

22. A machine readable storage medium storing instructions which when executed by a data processing system cause the data processing system to perform a method of processing data, the method comprising:
