Abstract
A data volume may be shelved based at least in part on statistical triggers associated with the data, a user of the data, or a system configured to store and/or manage the data. Upon receiving a request to detach a data volume from a computing device, a determination of whether the data volume should be shelved may be made. In some aspects, the data volume may be shelved by moving the data to another storage system, storing an identifier of the data volume, and de-allocating space associated with the shelved data such that the shelved data is no longer maintained in the storage system. Further, in some aspects, upon a request to attach the data volume, the data may be moved back, the original identifier may be re-assigned to the data volume, and the data volume may be re-attached to the computing device.
