Abstract

A method, apparatus and computer program product for managing data storage and access on a computing device. The computing device includes at least a first storage system and a second storage system. A unified file system interface is provided for facilitating interaction with the computing device, the unified file system interface configured as a file system capable of facilitating interaction with content of both the first storage system and the second storage system. Storage of content across the first storage system and the second storage system is managed in accordance with a rule set. File locations within the unified file system interface are independent of locations of corresponding content of the first storage system and the second storage system.

wherein the alias file path structure is unaffected by the moving of the data of the data files to different ones of the first storage system and the second storage system.

2. The method according to claim 1, wherein each alias file is associated with one of the data files based at least in part on contents of a lookup table stored in memory, the method further comprising updating said contents of the lookup table as the data of the data files is moved to different ones of the first storage system and the second storage system.

3. The method according to claim 1, wherein each alias file is associated with one of the data files is constructed dynamically based on contents of stored metadata, the metadata associated with the data of the data files stored on the first storage system and the second storage system.

4. The method according to claim 1, wherein the first storage system and the second storage system are each associated with a priority level, and wherein managing storage comprises moving the data of the data files preferentially to different ones of the first and second storage system based on the priority levels.

5. The method according to claim 1, wherein managing storage comprises one or more of:

managing storage of the data of data files stored on the first storage system and the second storage system in accordance with the rule set to move the data of the data files to different ones of the first storage system and the second storage system in accordance with one or more performance optimization criteria;

managing storage of the data of data files stored on the first storage system and the second storage system in accordance with the rule set to move the data of the data files to different ones of the first storage system and the second storage system in accordance with one or more load balancing criteria;

managing storage of the data of data files stored on the first storage system and the second storage system in accordance with the rule set to move the data of the data files to different ones of the first storage system and the second storage system based on file size; and

managing storage of the data of data files stored on the first storage system and the second storage system in accordance with the rule set to move the data of the data files to different ones of the first storage system and the second storage system based on file type.

6. The method according to claim 1, wherein at least one of the first storage system and the second storage system is selected from the group comprising:

virtual storage systems;

removable storage systems;

internal storage systems;

remote storage systems; and

cloud-based storage systems.

7. The method according to claim 1, wherein interaction with the unified file system interface is performed via a first syntax, and interaction with at least one of the first storage system and the second storage system is performed via a second syntax, different from the first syntax, the method further comprising translating between the first syntax and the second syntax.

8. The method according to claim 1, further comprising performing data synchronization operations via the unified file system interface.

18. The method according to claim 1, wherein at least a portion of the data of one or more of data files is stored on both the first storage system and the second storage system.

9. An apparatus for facilitating data storage and access on a computing device, the computing device associated with at least a first storage system and a second storage system, the apparatus comprising:

a unified file system interface configured to to provide access to data of data files stored on at least one of the first storage system and the second storage system, the unified file system interface comprising alias files accessible via an alias file path structure, each alias file associated with one of the data files; and

an inter-storage system management module configured to

manage storage of the data of the data files on the first storage system and the second storage system in accordance with a rule set to move the data of the data files to different ones of the first storage system and the second storage system to adjust free space on the first storage system and the second storage system;

wherein the alias file path structure is independent of whether the data of the data files is stored on the first storage system or the second storage system; and

wherein the alias file path structure is unaffected by moving of the data of the data files to different ones of the first storage system and the second storage system.

10. The apparatus according to claim 9, wherein each alias file is associated with one of the data files based at least in part on contents of a lookup table stored in memory, the method further comprising updating said contents of the lookup table as the data of the data files is moved to different ones the first storage system and the second storage system.

11. The apparatus according to claim 9, wherein each alias file is associated with one of the data files is constructed dynamically based on contents of stored metadata, the metadata associated with the data of the data files stored on the first storage system and the second storage system.

12. The apparatus according to claim 9, wherein the first storage system and the second storage system are each associated with a priority level, and wherein managing storage comprises moving the data of the data files preferentially to different ones of the first and second storage system based on the priority levels.

13. The apparatus according to claim 9, wherein managing storage of content comprises one or more of:

managing storage the data of data files stored on the first storage system and the second storage system in accordance with the rule set to move the data of the data files to different ones of the first storage system and the second storage system in accordance with one or more performance optimization criteria;
