Abstract

A method and system for assigning service level objectives to data objects stored within a computer system. The computer system includes an information management server for providing customized services to data objects residing in the computer system. One exemplary method identifies a data object, such as a file, folder, database, and the like, that has been categorized according to at least one property associated with the data object. The method also identifies service level objectives that are available within the computer system. Service level objectives may include any type of service area or service level that can be provided to a data object. The data object is then associated with one or more of the service level objectives for requesting that the services associated with the one or more service level objectives be provided to the data object.

23. The method as recited in claim 1, wherein the intrinsic property of the data object upon which the categorization of the data object is based comprises one or more of the content of the data object, the organization, group or individual that created the data object, and metadata of the data object, and any combination of one or more of the foregoing.

24. The method as recited in claim 23, further comprising using the metadata of the object to determine one or more intrinsic properties of the data object, wherein the one or more intrinsic properties include a date of last use of the data object, an owner of the data object, a date of creation of the data object, a file size of the data object, a file type of the data object, a disposition date of the data object, content of the data object, and any combination of one or more of the foregoing.

6. In a computer system that includes an information management server for providing services to data objects residing in the computer system, a method for assigning the data objects to service providers in order to customize the services provided to the data objects, the method comprising an information management server performing:

identifying services that are available in the computer system and that can be provided to the data objects in the computer system;

identifying service level objectives, wherein each service level objectives is associated with at least one of the services;

identifying a data object associated with at least one service level objective, each service level objective associated with the data object is mapped to the data object based on a category assigned to the data object, the category having been assigned to the data object based on one or more intrinsic properties of the data object;

determining a target service package based on the at least one service level objective mapped to the data object and based on global rules that apply to more than one of the data objects, wherein the target service package includes a list of services;

identifying a service package that is capable of providing at least one of the services identified in the target service package; and

associating the identified service package with the data object, wherein services included in the identified service package are provided to the data object, wherein other data objects are associated with the same service package or with other service packages such that each data object receives services that are customized based on the how the other data objects are mapped to the service level objectives.

7. A method as recited in claim 6, further comprising:

providing the user, via a user interface, with a finite number of selectable service packages, each service package containing a plurality of service levels.

8. A method as recited in claim 6, further comprising:
