The 8 mm Backup Format is a Magnetic Tape Data Storage format used in Computer systems, pioneered by Exabyte Corporation . It is also known as '''Data8'''. Such systems can backup up to 40 GB of data depending on configuration. The tapes used are mechanically the same as the tapes used in 8 Mm Video Format recorders and Camcorders . Until the advent of AIT , Exabyte were the sole vendor of 8 mm format tape drives. The company was formed with the aim of taking the 8 mm video format and make it suitable for data storage. They did so by building a reliable mechanism and data format that used the common 8 mm video tape technology that was available then. This was the first form of helical-scan tape used commercially for data storage. Exabyte's first 8 mm tape drive was available in 1987. This was followed up with their Mammoth tape drive in 1996, and the Mammoth-2 (M2) in 1999. Exabyte's drive mechanisms were frequently rebranded and integrated into UNIX systems. GENERATIONS ''NOTE: The AIT and VXA formats and some other less common formats also use 8 mm wide tape, but are completely incompatible.'' Compatibility between tapes and drives and native capacities (GB) Legend:
Exabyte 8 mm These drives use Metal Particle (MP) tape.
Mammoth These drives use Advanced Metal Evaporated (AME) tape, but could also read (but not write) MP tapes.
Mammoth-2 (M2) These drives used Advanced Metal Evaporated (AME) tape with an 2 m integrated cleaning tape header called ''Smart Clean''.
