The IBM Linear Tape File System - Single Drive Edition, (initially released as "IBM Long Term File System"), allows tapes to be formatted as an LTFS volume, and for these volumes to be mounted - and users and applications access files and directories stored on the tape directly, including drag-and-drop of files.
The IBM Ultrium 6 technology is designed to support media partitioning, IBM Linear Tape File System (LTFS) technology and encryption of data and WORM cartridges. [ 41 ] TS2260 – Half-height external standalone or rack mountable shelf unit with a native physical capacity of 2.5 TB.
James T, Brady while in IBM Poughkeepsie Lab conceived a log structured paging file system in 1979 which was implemented in MVS SP2 in 1980. [1] [2] John K. Ousterhout and Mendel Rosenblum implemented the first log-structured file system for the Sprite operating system in 1992. [3] [4]
Tahoe-LAFS (Tahoe Least-Authority File Store [5]) is a free and open, secure, decentralized, fault-tolerant, distributed data store and distributed file system. [6] [7] It can be used as an online backup system, or to serve as a file or Web host similar to Freenet, [citation needed] depending on the front-end used to insert and access files in the Tahoe system.
Linear Tape-Open (LTO), also known as the LTO Ultrium format, [1] is a magnetic tape data storage technology used for backup, data archiving, and data transfer.It was originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats available at the time.
GitHub (/ ˈ ɡ ɪ t h ʌ b /) is a proprietary developer platform that allows developers to create, store, manage, and share their code.

Early IBM tape drives, such as the IBM 727 and IBM 729, were mechanically sophisticated floor-standing drives that used vacuum columns to buffer long u-shaped loops of tape. Between servo control of powerful reel motors, a low-mass capstan drive, and the low-friction and controlled tension of the vacuum columns, fast start and stop of the tape ...
