Described are a method and apparatus for preserving data integrity which can be practiced in a data storage library that receives data from a host computer. The data storage library includes a docking station that stores data to and from an operatively linked mobile random access storage device. Once the data is stored on the mobile random access storage device, the elapsed time is accounted for. The mobile random access storage device is adapted to be unlinked from the docking station, such as for purposes of archiving the mobile random access storage device. A user can be notified when the elapsed time has reached a time limit. Upon indicating that the data on mobile random access storage device should be restored, the mobile random access storage device can be re-linked with the docking station for data restoration, thus, starting a new elapsed time.
