Abstract
A storage subsystem provides redundancy protection for data associated with files stored in a storage subsystem. A request is received to change the redundancy protection for data associated with at least one of the files, where the request identifies the data for which the redundancy protection is to be changed. The redundancy protection for the data identified by the request is changed, while the redundancy protection for a remainder of the data associated with the files stored in the storage subsystem is maintained unchanged.
