Abstract: A method for backing up and recovering data is disclosed. Data representing an allocation of a plurality of backup resources to a plurality of restricted data zones is stored in a storage device. Any of the plurality of backup resources allocated to one restricted data zone is not allocated to another restricted data zone. A user is associated with one of the plurality of restricted data zones. Backup and recovery services are provided to the user using one or more backup resources allocated to the restricted data zone associated with the user. The backup and recovery services provided to the user are segregated from backup and recovery services provided to other users associated with restricted data zones that are different from the restricted data zone associated with the user.

Abstract: A method of backing up data is disclosed. Information is collected from a file system corresponding to an initial backup set, wherein the initial backup set comprises a set of data configured to be backed up, and wherein the collected information comprises information regarding how the initial backup set is organized within the file system. Two or more subdivided backup sets are determined based at least in part on the collected information. The two or more subdivided backup sets are backed up.
