Abstract

Embodiments of systems and methods for storing documents in a cloud storage system comprising a cloud processor and a plurality of storage components are disclosed. Particularly, certain embodiments comprise, at the cloud processor, providing at least one storage component attribute for each of the plurality of storage components, the at least one storage component attribute defining a storage property of the respective storage component; receiving a first document to be stored and document metadata associated with the first document, the document metadata defining storage requirement of the first document; translating the document metadata of the first document into a storage instruction; determining, based on storage component attributes, at least one storage component among the plurality of storage components with a defined storage property matching the storage instruction for the first document; and storing the first document in the at least one storage component determined according to the storage instruction.

Claims

1. A method for storing documents in a cloud storage system comprising a cloud processor and a plurality of storage components, the method comprising:

at the cloud processor,

providing at least one storage component attribute for each of the plurality of storage components, the at least one storage component attribute defining a storage property of the respective storage component;

receiving a first document to be stored and document metadata associated with the first document, the document metadata defining a storage requirement of the first document;

translating the document metadata of the first document into a storage instruction;

determining, based on storage component attributes, at least one storage component among the plurality of storage components with a defined storage property matching the storage instruction for the first document; and

storing the first document in the at least one storage component determined according to the storage instruction.

2. The method according to claim 1, further comprising:

at the cloud processor,

generating cloud storage information associated with the first document stored in the cloud storage system indicating the at least one storage component at which the first document is stored.

3. The method according to claim 2, wherein the cloud storage information associated with the first document includes the document metadata of the first document.

4. The method according to claim 1, further comprising:

storing the document metadata associated with the first document in the at least one determined storage component.

5. The method according to claim 1, further comprising:

at the cloud processor,

receiving a request indicating a document to be retrieved from the cloud storage system;

searching for cloud storage information associated with the document to be retrieved to identify the at least one storage component at which the document to be retrieved is stored; and

retrieving the document from the at least one identified storage component.

6. The method according to claim 1, wherein the providing at least one storage component attribute for each of the plurality of storage components further comprises:

at the cloud processor,

requesting the at least one storage component attribute associated with each of the plurality of storage components; and

, in response

receiving the at least one storage component attribute provided by the respective storage component.

7. The method according to claim 6, wherein the providing at least one storage component attribute for each of the plurality of storage components further comprises:

at the cloud processor,

storing the at least one storage component attribute received from the respective storage component; and

associating the at least one storage component attribute with the respective storage component.

8. The method according to claim 1, wherein the determining further comprises:

sorting the storage components based on a level of match between the storage property of each storage component and the storage instruction for the first document; and

selecting, based on the level of match exceeding a predetermined threshold, the at least one storage component.

9. The method according to claim 1, further comprising:

at the cloud processor,

receiving new document metadata to update the originally received document metadata for the first document;

translating the new document metadata into a new storage instruction;

determining based on the storage component attributes whether the storage property of the at least one storage component at which the first document is stored matches with the new storage instruction; and

in case of a match, updating the originally received document metadata for the first document with the new document metadata, otherwise determining based on storage component attributes at least one new storage component among the plurality of storage components with a defined storage property matching the new storage instruction and storing the first document in the at least one newly determined storage component.

10. The method according to claim 9, further comprising:

at the cloud processor,

updating cloud storage information associated with the first document to indicate the at least one new storage component at which the first document is stored.

11. The method according to claim 9, wherein storing the first document in the at least one new storage component further comprises:

searching for cloud storage information associated with the first document;

moving the first document from the at least one storage component indicated by the cloud storage information to the at least one new storage component determined; and

updating the cloud storage information associated with the first document to indicate the at least one new storage component at which the first document is stored.

12. The method according to claim 1, wherein the translating the document metadata of the first document into the storage instruction comprises:

mapping the document metadata to at least one of the storage component attributes of the storage components based on a predefined mapping table, wherein the storage instruction contains the at least one storage component attribute.

13. The method according to claim 1, further comprising:

at the cloud processor,

determining whether a failure occurs in at least one storage component among the plurality of storage components;

searching for cloud storage information indicating a document stored in the at least one storage component at which the failure occurs;

based on the searching for cloud storage information, determining whether a copy of the document exists, and retrieving document metadata associated with the copy of the document;

translating the document metadata of the copy of the document into a storage instruction to restore the document;

determining, based on storage component attributes, at least one storage component of which the storage property matches with the storage instruction to restore the document;

restoring the document by copying the copy of the document from the at least one storage component indicated by the cloud storage information to the at least one storage component determined.

14. The method according to claim 13, further comprising:

updating the cloud storage information associated with the copy of the document to indicate the at least one storage component to which the copy has been copied.

15. A cloud processor for a cloud storage system comprising a plurality of storage components, the cloud processor having means configured to perform functions in accordance with the method according to claim 1.

16. A cloud storage system, comprising:

a plurality of storage components; and

a cloud processor having means configured to perform functions in accordance with the method according to claim 1.

17. A non-transitory computer readable medium, comprising instructions which when executed by a cloud processor in a cloud storage system having a plurality of storage components configure the cloud processor so as to perform the method according to claim 1.
