Abstract

A method, computer program product, and computing system for establishing a first file system protocol connection between a first storage system and a second storage system. A security descriptor of one or more electronic files on the first storage system may be queried for security-related information using the first file system protocol connection. Security-related information associated with a first file system protocol and security-related information associated with a second file system protocol may be migrated from the first storage system to the second storage system.

First claim

What is claimed is:

1. A computer-implemented method, executed on a computing device, comprising:
establishing a first file system protocol connection between a first storage system and a second storage system, wherein the first file system protocol connection is a single file system protocol connection between the first storage system and the second storage system;
querying a security descriptor of one or more electronic files on the first storage system for security-related information using the first file system protocol connection; and
in response to querying the security descriptor of the one or more electronic files on the first storage system for security-related information, migrating security-related information associated with a first file system protocol and security-related information associated with a second file system protocol from the first storage system to the second storage system with only the first file system protocol connection.

2. The computer-implemented method of claim 1 , wherein the one or more electronic files are accessible using the first file system protocol and the second file system protocol.

3. The computer-implemented method of claim 1 , wherein the first file system protocol is Common Internet File System (CIFS).

4. The computer-implemented method of claim 3 , wherein the security-related information associated with the first file system protocol includes one or more of: an owner security identifier (SID), a group SID, and an access control list.

5. The computer-implemented method of claim 1 , wherein the second file system protocol is Network File System (NFS).

6. The computer-implemented method of claim 5 , wherein the security-related information associated with the second file system protocol includes one or more of: a user identifier (UID), a group identifier (GID), and one or more permission mode bits.

7. The computer-implemented method of claim 1 , further comprising:
encoding the security-related information associated with the second file system protocol in the security descriptor of the one or more electronic files.

8. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
establishing a first file system protocol connection between a first storage system and a second storage system, wherein the first file system protocol connection is a single file system protocol connection between the first storage system and the second storage system;
querying a security descriptor of one or more electronic files on the first storage system for security-related information using the first file system protocol connection; and
in response to querying the security descriptor of the one or more electronic files on the first storage system for security-related information, migrating security-related information associated with a first file system protocol and security-related information associated with a second file system protocol from the first storage system to the second storage system with only the first file system protocol connection.

9. The computer program product of claim 8 , wherein the one or more electronic files are accessible using the first file system protocol and the second file system protocol.

10. The computer program product of claim 8 , wherein the first file system protocol is Common Internet File System (CIFS).

11. The computer program product of claim 10 , wherein the security-related information associated with the first file system protocol includes one or more of: an owner security identifier (SID), a group SID, and an access control list.

12. The computer program product of claim 8 , wherein the second file system protocol is Network File System (NFS).

13. The computer program product of claim 12 , wherein the security-related information associated with the second file system protocol includes one or more of: a user identifier (UID), a group identifier (GID), and one or more permission mode bits.

14. The computer program product of claim 8 , wherein the operations further comprise:
encoding the security-related information associated with the second file system protocol in the security descriptor of the one or more electronic files.

15. A computing system comprising:
a memory; and
a processor configured to establish a first file system protocol connection between a first storage system and a second storage system, wherein the first file system protocol connection is a single file system protocol connection between the first storage system and the second storage system, wherein the processor is further configured to query a security descriptor of one or more electronic files on the first storage system for security-related information using the first file system protocol connection, and wherein the processor is further configured to, in response to querying the security descriptor of the one or more electronic files on the first storage system for security-related information, migrate security-related information associated with a first file system protocol and security-related information associated with a second file system protocol from the first storage system to the second storage system with only the first file system protocol connection.

16. The computing system of claim 15 , wherein the one or more electronic files are accessible using the first file system protocol and the second file system protocol.

17. The computing system of claim 15 , wherein the first file system protocol is Common Internet File System (CIFS).

18. The computing system of claim 17 , wherein the security-related information associated with the first file system protocol includes one or more of: an owner security identifier (SID), a group SID, and an access control list.

19. The computing system of claim 15 , wherein the second file system protocol is Network File System (NFS).

20. The computing system of claim 19 , wherein the security-related information associated with the second file system protocol includes one or more of: a user identifier (UID), a group identifier (GID), and one or more permission mode bits.
