Abstract

Embodiments of the invention relate to methods and systems for efficiently sharing assets such as files and folders between a host computer system and a client computer system while minimizing the amount of work the client must perform to efficiently transfer an asset. In one or more embodiments, assets such as files and folders that are to be shared or transferred are placed in appropriate network slice queues by the hosts rather than the clients. These network slice queues allow the files and folders to be placed in slices without utilizing the resources of the clients as well as much of the available network resources. This ensures efficient use of network resources, while minimizing the amount of work the hosts and/or clients must perform in order to perform a backup.

First claim

What is claimed is:

1. A method for sharing files, the method comprising: receiving, by a production host, a request from a client for an asset located on the production host; retrieving file-system meta-data associated with the asset; analyzing the file-system meta-data to determine how to divide a data associated with the asset into slices, wherein the data comprises a plurality of files, wherein analyzing the file-system meta-data determines a total size, and a number, of the plurality of files; slicing the data associated with the asset into the slices based on the total size, and the number, of the plurality of files; and sending the slices to the client.

2. The method of claim 1 , the method further comprising:
assigning an identification to each slice of the slices;
adding the identification for each slice of the slices to a slice list for the asset; and
saving the slice list for the asset in a slice list cache.

3. The method of claim 2 , wherein the slice list cache is stored in local storage of the production host.

4. The method of claim 3 , wherein if the production host determines that the meta-data associated with the asset has changed, the production host updates the slice list.

5. The method of claim 3 , wherein the slice list for the asset is stored in the slice list cache for a predetermined amount of time before the slice list is deleted.

6. The method of claim 2 , the method further comprising:
receiving a subsequent request from a second client for the asset;
retrieving the slice list stored in the slice list cache;
slicing the data associated with the asset in accordance with the slice list stored in the slice list cache to obtain the slices; and
sending the slices to the second client.

7. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for sharing files, the method comprising: receiving, by a production host, a request from a client for an asset located on the production host; retrieving system meta-data associated with the asset; analyzing the file-system meta-data to determine how to divide a data associated with the asset into slices, wherein the data comprises a plurality of files, wherein analyzing the file-system meta-data determines a total size, and a number, of the plurality of files; slicing the data associated with the asset into the slices based on the total size, and the number, of the plurality of files; and sending the slices to the client.

8. The non-transitory computer readable medium of claim 7 , the method further comprising:
assigning an identification to each slice of the slices;
adding the identification for each slice of the slices to a slice list for the asset; and
saving the slice list for the asset in a slice list cache.

9. The non-transitory computer readable medium of claim 8 , wherein the slice list cache is stored in local storage of the production host.

10. The non-transitory computer readable medium of claim 9 , wherein if the production host determines that the meta-data associated with the asset has changed, the production host updates the slice list.

11. The non-transitory computer readable medium of claim 9 , wherein the slice list for the asset is stored in the slice list cache for a predetermined amount of time before the slice list is deleted.

12. The non-transitory computer readable medium of claim 8 , the method further comprising:
receiving a subsequent request from a second client for the asset;
retrieving the slice list stored in the slice list cache;
slicing the data associated with the asset in accordance with the slice list stored in the slice list cache to obtain the slices; and
sending the slices to the second client.

13. A system comprising: a production host comprising: a processor; and a memory operatively connected to the processor and comprising instructions, which when executed by the processor, perform a method for sharing files, the method comprising: receiving a request from a client for an asset located on the production host; retrieving file-system meta-data associated with the asset; analyzing the file-system meta-data to determine how to divide a data associated with the asset into slices, wherein the data comprises a plurality of files, wherein analyzing the file-system meta-data determines a total size, and a number, of the plurality of files; slicing the data associated with the asset into the slices based on the total size, and the number, of the plurality of files; and sending the slices to the client.

14. The system of claim 13 , the method further comprising:
assigning an identification to each slice of the slices;
adding the identification for each slice of the slices to a slice list for the asset; and
saving the slice list for the asset in a slice list cache.

15. The system of claim 14 , wherein the slice list cache is stored in local storage of the production host.

16. The system of claim 15 , wherein if the production host determines that the meta-data associated with the asset has changed, the production host updates the slice list.

17. The system of claim 15 , wherein the slice list for the asset is stored in the slice list cache for a predetermined amount of time before the slice list is deleted.

18. The system of claim 14 , the method further comprising:
receiving a subsequent request from a second client for the asset;
retrieving the slice list stored in the slice list cache;
slicing the data associated with the asset in accordance with the slice list stored in the slice list cache to obtain the slices; and
sending the slices to the second client.
