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.
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.
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.
The Linear Tape File System is a method of storing file metadata on a separate part of the tape. This makes it possible to copy and paste files or directories to a tape as if it were a disk, but does not change the fundamental sequential access nature of tape. [citation needed]
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.
When developing BeeGFS, Fraunhofer aimed to create a software focused on scalability, flexibility and usability. BeeGFS runs on any Linux machine and consists of several components that include services for clients, metadata servers and storage servers. In addition, there is a service for the
In 2012, Quantum introduced its Scalar LTFS (Linear Tape File System) appliance, which offers new modes of portability and user accessibility for archived content on LTO tape. [52] In 2016, Quantum refreshed its Scalar LTO tape library family and added an appliance for rich media archiving.
The IBM implementation of this file system has been released as the open-source IBM Linear Tape File System — Single Drive Edition (LTFS-SDE) product. The Linear Tape File System uses a separate partition on the tape to record the index meta-data, thereby avoiding the problems associated with scattering directory entries across the entire tape.
