The Linear Tape File System (LTFS) is a file system that allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data.
IBM offers four options: IBM LTFS Single Drive Edition – access and manage data on a standalone tape drive as if the data were on disk; IBM LTFS Library Edition – access and manage data on single or multiple cartridges in a tape library; IBM LTFS Storage Manager – manage both online and offline files in IBM tape libraries
This is an incomplete list of log-structured file system implementations. 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 ...
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses. Software that fits the Free Software Definition may be more appropriately called free software ; the GNU project in particular objects to their works being referred to as open-source . [ 1 ]
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.
A log-structured filesystem is a file system in which data and metadata are written sequentially to a circular buffer, called a log.The design was first proposed in 1988 by John K. Ousterhout and Fred Douglis and first implemented in 1992 by Ousterhout and Mendel Rosenblum for the Unix-like Sprite distributed operating system.
PDFtk (short for PDF Toolkit) is a toolkit for manipulating Portable Document Format (PDF) documents. [ 3 ] [ 4 ] It runs on Linux , Windows and macOS . [ 5 ] It comes in three versions: PDFtk Server ( open-source command-line tool ), PDFtk Free ( freeware ) and PDFtk Pro ( proprietary paid ). [ 2 ]
On later operating systems, it was written in the common language of those systems – for example, the C language under Unix, and Zetalisp under the Lisp Machine system. GNU ‘s info help system was originally an EMACS subsystem, and then was later written as a complete standalone system for Unix-like machines.
