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 is 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 executing on one or more computer processors into at least first and second groups;

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

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

reassigning one or more of the storage system components associated with the first group to both the first group and 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.

2. The method of claim 1, wherein the one or more storage system components associated with the first group that are reassigned to both the first group and the second group, automatically inherits the second storage policy associated with the second group while retaining the first storage policy associated with the first group.

3. The method of claim 1, wherein in the event a non-conflict storage operation associated with the first storage policy is to be performed on a reassigned storage system component, performing the non-conflict storage operation in accordance with the first storage policy.

4. The method of claim 1, wherein in the event a non-conflict storage operation associated with the second storage policy is to be performed on a reassigned storage system component, performing the non-conflict storage operation in accordance with the second storage policy.

5. The method of claim 1, 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.

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

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

multiple storage system components comprising one or more computer processors, wherein at least a first storage system component is associated with a first group of storage system components and at least a second storage system component is associated with a second group of storage system components;

at least a first storage policy which defines one or more retention storage preferences associated with the first group;

at least a second storage policy defining one or more retention storage preferences associated with the second group; and

wherein in the event the first storage component is reassigned to both the first group and the second group, the first storage system component inherits the second storage policy associated with the second 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.

8. The computer system of claim 7, wherein the one or more storage system components associated with the first group that are reassigned to both the first group and the second group, automatically inherits the second storage policy associated with the second group while retaining the first storage policy associated with the first group.

9. The computer system of claim 7, wherein in the event a non-conflict storage operation associated with the first storage policy is to be performed on a reassigned storage system component, performing the non-conflict storage operation in accordance with the first storage policy.

10. The computer system of claim 7, wherein in the event a non-conflict storage operation associated with the second storage policy is to be performed on a reassigned storage system component, performing the non-conflict storage operation in accordance with the second storage policy.

11. The computer system of claim 7, 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.

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

13. A method for configuring a storage system for the performance of storage operations, the method comprising:

assigning a plurality of storage system components executing in one or more computer processors into multiple groups, wherein the multiple groups have different storage policies associated therewith;

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

14. The method of claim 13, wherein the one or more storage system components associated with the first group that are reassigned to both the first group and the second group, automatically inherits the second storage policy associated with the second group while retaining the first storage policy associated with the first group.

15. The method of claim 13, wherein in the event a non-conflict storage operation associated with the first storage policy is to be performed on a reassigned storage system component, performing the non-conflict storage operation in accordance with the first storage policy.

16. The method of claim 13, wherein in the event a non-conflict storage operation associated with the second storage policy is to be performed on a reassigned storage system component, performing the non-conflict storage operation in accordance with the second storage policy.

17. The method of claim 13, 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 13, wherein the storage system components comprise sub-client components of a plurality of clients, the clients being data sources for the storage operation.

19. The method of claim 18, wherein assigning storage system components comprises assigning the sub-client components to comprise subsets of client applications that identify common portions of client data.

20. The method of claim 18, 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.
