ABSTRACT:
A tape drive method and system for backing up data files from a hard drive to a tape drive or restoring data files to a hard drive from a tape drive. The data transfer rate of the tape drive is adjusted to minimize the number of times the tape drive switches off to wait for the hard drive to catch up to the tape drive. By minimizing the number of off occurrences of the tape drive, the back-up or restoration operation is completed more quickly.
