Abstract
Methods, storage controllers, and systems for backing data of a non-volatile storage device using a backing store are described. One method includes satisfying storage operations using a non-volatile storage device, determining an age for data stored on the non-volatile storage device, and copying data of the non-volatile storage device having an age that satisfies a data retention time threshold to a dedicated backing store. One storage controller includes an operations module that satisfies storage operations using a non-volatile storage device, an age module that determines an age for data stored on the non-volatile storage device, and a backup module that copies data of the non-volatile storage device having an age that satisfies a data retention time threshold to a dedicated backing store.
