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.
Since LTFS is an open standard, LTFS-formatted tapes are usable by a wide variety of computing systems. The block structure of the tape is logical so interblock gaps, file marks, tape marks and so forth take only a few bytes each. In LTO-1 and LTO-2, this logical structure has CRC codes and compression added to create blocks of 403,884 bytes.
Linear Tape-Open LTO-4: 800 GB: 2008 IBM TS1130: 1 TB: Encryption capability integrated into the drive 2008 StorageTek T10000B: 1 TB: 2010 Linear Tape-Open LTO-5: 1.5 TB: Linear Tape File System (LTFS), which allows accessing files on tape in the file system directly (similar to disk filesystems) without an additional tape library database 2011 ...
File archiver and backup tools have been created to pack multiple files along with the related metadata into a single tape file. Serpentine tape drives (e.g., QIC) offer improved access time by switching to the appropriate track; tape partitions are used for directory information. [24] The Linear Tape File System is a method of storing file ...
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.
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.
