Linear Tape File System (LTFS)
SNIA's Linear Tape File System (LTFS) Technical Work Group is focusing technical efforts on the development of an architecture that is related to the on-tape format for LTFS. The architecture also produces a comprehensive set of specifications ensuring a consistency of interface standards across LTFS related efforts.
LTFS refers to both the format of data recorded on magnetic tape media and the implementation of specific software that uses this data format to provide a file system interface to data stored on magnetic tape.
LTFS provides an industry standard format for recording data on modern magnetic tape.
This standard allows for:
LTFS Format Specification
The LTFS specification became part of the SNIA family of standards in 2012 donated by a vendor to SNIA as a vendor specific proprietary standard to become an open SNIA standard.
The LTFS Format is particularly suited to these usages:
The LTFS Format has these features:
LTFS Bulk Transfer Standard
The LTFS Bulk Transfer standard defines a method by which a set of files, directories and objects from a source system can be transferred to a destination system. The bulk transfer of large quantities of data is well suited for LTFS due to the economic and environmental characteristics of tape.
Building on top of the LTFS format, a standardized method for transferring data is defined that provides many advantages such as:
The LTFS Bulk Transfer standard is specifically targeted for the following use cases:
Documents and Resources
Vendor Extended Attributes
The LTFS format allows for vendor specific extended atrributes. It is recommended that a vendor (a company, organization, or technology standard) reserve their name. Refer to Appendix C of the Format Specification.
