Linear Tape File System (LTFS)
See IBM Spectrum Archive.
Linear Tape-Open (LTO)
A type of tape storage technology that is developed by the IBM Corporation, Hewlett-Packard, and Certance. LTO technology is an “open format” technology, which
means that its users have multiple sources of product and media. The “open” nature of LTO technology enables compatibility between different vendors' offerings
by ensuring that vendors comply with verification standards. The LTO technology is implemented in two formats: the Accelis format focuses on fast access; the
Ultrium format focuses on high capacity. The Ultrium format is the preferred format when capacity (rather than fast access) is the key storage consideration. An
Ultrium cartridge has a compressed data capacity of up to 800 GB (2:1 compression) and a native data capacity of up to 400 GB.
