Abstract

In various embodiments, methods and systems for providing access to file systems are provided. An SFA-based operation having an operation modifier for a file in a file system is received. The SFA-based operation is defined based on a file-representational state transfer (REST) interface. The SFA-REST interface comprises integrated functionality of an SFA protocol and REST protocol. The SFA-based operation is executed using the operation modifier. A REST-based operation for the file in the distributed file storage is received. The REST-based operation is defined based on the SFA-REST interface. The operation modifier is referenced in order to execute the REST-based operation. The REST-based operation based on the SFA-REST interface. A schema can be implemented for accessing the file system. The schema includes tables to store files, the table comprises fields corresponding to elements of a SFA-REST interface. A snapshot component can be implemented to backup file shares in the file system.

First claim

1 . A computerized system comprising:
one or more computer processors; and computer memory storing computer-useable instructions that, when used by the one or more computer processors, cause the one or more computer processors to perform operations comprising: storing state information for files of a file system, wherein the files are stored in a file service schema comprising a plurality of tables, wherein the plurality of tables store the state information of the files of the file system, and wherein the plurality of tables comprise fields corresponding to elements of an Shared File Access-Representation State Transfer “SFA-REST” interface, and wherein the SFA-REST interface comprises integrated functionality of an SFA protocol and REST protocol for accessing files in the file system.

2 . The system of claim 1 , wherein the plurality of tables are hierarchical tables for storing the files and corresponding directories based on corresponding names of the files and the directories.

3 . The system of claim 1 , further comprising a namespace table, wherein the namespace table is a primary table of the file schema, wherein the files and corresponding directories are retrieved using lookups to the namespace table storing a plurality of file identifiers associated with the files.

4 . The system of claim 1 , further comprising a file information table, wherein the file information table stores information about the content of the files, wherein the file information table comprises a plurality of timestamps fields for the files.

5 . The system of claim 1 , further comprising:
a file page range table, wherein the file page range table comprises data associated with files, wherein a key for the table comprises a file identifier and an offset size of a page range stored for a file; a handle table, wherein the handle table comprises one or more open handles for SFA-REST interface operations; and a lease table, wherein the lease table stores leases associated with the files.

6 . The system of claim 1 , further comprising a change notify table and a change notify events table, the change notify table is updated upon a registration to detect changes within a direction and change notify events table is update upon occurrence of an event that is stored.

7 . The system of claim 1 , further comprising a byte range lock table, wherein the byte range locks files using at least a lock identifier and a handle identifier.

8 . One or more computer-storage media having computer-executable instructions embodied thereon that, when executed by a computing system having a processor and memory, cause the processor to:
storing state information for files of a file system, wherein the files are stored in a file service schema comprising a plurality of tables, wherein the plurality of tables store the state information of the files of the file system, and wherein the plurality of tables comprise fields corresponding to elements of an Shared File Access-Representation State Transfer “SFA-REST” interface, and wherein the SFA-REST interface comprises integrated functionality of an SFA protocol and REST protocol for accessing files in the file system.

9 . The media of claim 8 , wherein the plurality of tables are hierarchical tables for storing the files and corresponding directories based on corresponding names of the files and the directories.

10 . The media of claim 8 , further comprising a namespace table, wherein the namespace table is a primary table of the file schema, wherein the files and corresponding directories are retrieved using lookups to the namespace table storing a plurality of file identifiers associated with the files.

11 . The media of claim 8 , further comprising a file information table, wherein the file information table stores information about the content of the files, wherein the file information table comprises a plurality of timestamps fields for the files.

12 . The media of claim 8 , further comprising:
a file page range table, wherein the file page range table comprises data associated with files, wherein a key for the table comprises a file identifier and an offset size of a page range stored for a file; a handle table, wherein the handle table comprises one or more open handles for SFA-REST interface operations; and a lease table, wherein the lease table stores leases associated with the files.

13 . The media of claim 8 , further comprising a change notify table and a change notify events table, the change notify table is updated upon a registration to detect changes within a direction and change notify events table is update upon occurrence of an event that is stored.

14 . The media of claim 8 , further comprising a byte range lock table, wherein the byte range locks files using at least a lock identifier and a handle identifier.

15 . A computer-implemented method, the method comprising:
storing state information for files of a file system, wherein the files are stored in a file service schema comprising a plurality of tables, wherein the plurality of tables store the state information of the files of the file system, and wherein the plurality of tables comprise fields corresponding to elements of an Shared File Access-Representation State Transfer “SFA-REST” interface, and wherein the SFA-REST interface comprises integrated functionality of an SFA protocol and REST protocol for accessing files in the file system.

16 . The method of claim 15 , wherein the plurality of tables are hierarchical tables for storing the files and corresponding directories based on corresponding names of the files and the directories.

17 . The method of claim 15 , further comprising a namespace table, wherein the namespace table is a primary table of the file schema, wherein the files and corresponding directories are retrieved using lookups to the namespace table storing a plurality of file identifiers associated with the files.

18 . The method of claim 15 , further comprising a file information table, wherein the file information table stores information about the content of the files, wherein the file information table comprises a plurality of timestamps fields for the files.

19 . The method of claim 15 , further comprising:
a file page range table, wherein the file page range table comprises data associated with files, wherein a key for the table comprises a file identifier and an offset size of a page range stored for a file; a handle table, wherein the handle table comprises one or more open handles for SFA-REST interface operations; and a lease table, wherein the lease table stores leases associated with the files.

20 . The method of claim 15 , further comprising a change notify table and a change notify events table, the change notify table is updated upon a registration to detect changes within a direction and change notify events table is update upon occurrence of an event that is stored.
