6. The method of claim 1, wherein one or more of the multiple storage policies defines a percentage of free storage space.

7. The method of claim 1, wherein one or more of the multiple storage policies defines a frequency at which snapshots of the data on the data storage resource should be taken.

8. The method of claim 1, wherein one or more of the multiple storage policies defines a time period after which data on the data storage resource should be migrated to another data storage resource.

9. The method of claim 1, further comprising analyzing application configuration data to determine whether a risk is present in the particular physical data storage resource.

10. The method of claim 1, wherein one or more of the multiple storage policies further defines a weight relating to data stored on the particular physical data storage resource, wherein the weight corresponds to a priority value of the stored data.

11. The method of claim 1, wherein the particular physical data storage resource is associated with an identifier not used elsewhere on the network.

12. The method of claim 1, further comprising:

receiving data associated with a condition of a second storage operation cell comprising a second physical data storage resource, the data including at least one identifier of the second data storage resource;

normalizing the identifier of the second physical storage resource with respect to one or more identifiers used by other storage operation cells to identify the second physical storage resource, thereby generating a normalized identifier; and
