Abstract

Methods and systems are provided for associating a storage system component, e.g. a server, client, machine, sub-client, or other storage system component, with one or more other storage system components into a group. Storage preferences are defined for the group which are automatically associated with each component in the group. The storage preferences define how storage operations are to be performed on the storage system components.

Claims

1. A method for grouping networked storage system components, the method comprising:

associating a plurality of storage system components into a first group wherein the plurality of storage system components are associated with a client server system and comprise at least a plurality of storage system servers belonging to the first group;

associating the first group with a first storage policy which defines one or more retention storage preferences and storage procedures to be followed by the storage system components in the first group; and

in the event a first storage operation is performed on a storage system component associated with the first group, performing the first storage operation in accordance with the first storage policy associated with the first group;

associating a plurality of storage system components into a second group, wherein the plurality of storage system components associated with the client server system in the second group comprise at least a plurality of storage system servers;

associating the second group with a second storage policy which defines one or more retention storage preferences and storage procedures followed by the storage system components in the second group that are different than the retention storage preferences and storage procedures associated with the first group; and

in the event a second storage operation is performed on a storage system component associated with the second group, performing the second storage operation in accordance with the second storage policy associated with the second group;

reassigning one or more clients of the storage system associated with the second group to both the second group and the first group, the one or more clients associated with the reassigned storage system automatically inherits the first storage policy associated with the first group while retaining the second storage policy associated with the second group, and in the event a first operation associated with the first storage policy conflicts with a second operation associated the second storage policy, the storage policy associated with a higher priority controls;

in the event a third non-conflict storage operation associated with the first storage policy is to be performed on the reassigned storage system component, performing the third storage operation in accordance with the first storage policy; and

in the event a fourth non-conflict storage operation associated with the second storage policy is to be performed on the reassigned storage system component, performing the fourth storage operation in accordance with the second storage policy.

2. The method of claim 1, wherein associating the plurality of storage system components into the first group, comprises storing first group data representing the storage system components in an index.

3. The method of claim 1, comprising selecting a storage system component to belong to the first group.

4. The method of claim 3, wherein selecting comprises selecting the storage system component to belong to the first group based on one or more characteristics of the storage system component.

5. The method of claim 3, wherein selecting comprises selecting two or more storage system components having a common characteristic.

6. The method of claim 5, comprising generating data representing a new group based on the selection of the two or more storage system components, and identifying the two or more storage system components as belonging to the new group.

7. The method of claim 1, wherein the storage system components comprise sub-client components of a plurality of clients, the clients being data sources for the storage operation.

8. The method of claim 7, wherein the sub-client components comprise subsets of client applications that identify common portions of client data.

9. The method of claim 7, wherein storing comprises storing group data representing sub-clients having data taken from common directory structures on clients.

10. The method of claim 7, wherein storing comprises storing group data representing sub-clients having data for a common software application.

11. The method of claim 10, wherein the common software application comprises an email application.

12. The method of claim 11, wherein the common software application is a messaging application.

13. The method of claim 1, comprising storing second group data representing a second group of components and a plurality of second storage system components belonging to the second group, and associating the second group data with at least one second storage policy which defines one or more preferences by which a storage operation is to be performed on the second group of components belonging to the second group.

14. The method of claim 13, wherein multiple storage system components belong to both the first and second groups.

15. A system for grouping networked storage system components, the system comprising:

at least first and second storage system servers associated with a client server system;

at least one or more storage managers for associating at least the first storage system server with a first group of storage system components and at least the second storage system server with a second group of storage system components; and

at least one or more storage manager indexes coupled to the storage manager for storing data relating to at least a first storage policy which defines one or more retention storage preferences associated with the first group, and storing data relating to at least a second storage policy defining one or more retention storage preferences associated with the second group; and

one or more storage system clients associated with the second group that inherit the first storage policy based upon the reassignment of the storage system clients to the first group, and in the event a first storage operation associated with the first storage policy conflicts with a second storage operation associated with the second storage policy, the storage policy associated with a higher priority controls.

16. A method for configuring a storage system for the performance of storage operations, the storage system comprising a plurality of storage system components, the method comprising:

assigning each of a plurality of storage system components associated with a client server system into multiple groups, the storage system components in each group comprise at least one storage system server;

assigning to each of the groups, at least one storage system policy, each storage system policy defines one or more retention storage preferences associated with a storage operation to be performed on the storage system components in an assigned group;

performing a storage operation on a storage system component associated with a first group, in accordance with a first storage policy assigned to the first group;

performing a storage operation on a storage system component associated with a second group, in accordance with a second storage policy assigned to the second group;

reassigning one or more storage system clients associated with the second group to at least the first group, upon reassignment of the storage system clients to the first group, the one or more storage system clients inherits the first storage policy associated with the first group, and in the event the first storage operation associated with the first storage policy conflicts with the second storage operation associated with the second storage policy, the storage policy associated with a higher priority controls.

17. The method of claim 16, wherein assigning storage system components to one or more groups comprises selecting storage system components for a group based on the storage system components having a common characteristic.

18. The method of claim 17, wherein assigning storage system components comprises assigning hardware components to a group.

19. The method of claim 17, wherein assigning storage system components comprises assigning software components to a group.

20. The method of claim 19, wherein assigning storage system components comprises assigning components representing sub-clients of storage system clients, the storage system clients serving as sources of data for storage operations.

21. The method of claim 20, wherein assigning storage system components comprises assigning the sub-client components to comprise subsets of client applications that identify common portions of client data.

22. The method of claim 20, wherein assigning storage system components comprises assigning the sub-client components to a group based on the sub-clients having data taken from common directory structures on clients.
