Abstract
A set of one or more logical storage units is provisioned in a data storage system. Each logical storage unit is provisioned with a given storage capacity. A set of one or more object rules is applied to objects stored in the set of one or more logical storage units. The set of one or more object rules is configured to maintain available free storage space in each of the set of one or more logical storage units: (i) consistent with a desired free storage space level and an acceptable free storage space level; and (ii) consistent with an object retention policy comprising a desired retention time value and an acceptable retention time value for a given object.
