The LTFS format is a self-describing media format standardized by the Storage Networking Industry Association (SNIA), and IBM Spectrum Archive™ programs comply with this standard.
The LTFS format is a self-describing media format that contains a header that defines the format for the remainder of the file. The header includes instructions for data arrays, file elements and attributes, and the use of metadata.
IBM Spectrum Archive is an implementation of the Linear Tape File System™ specification and the first file system that works with LTO 5, TS1140, and later tapes. For the most current version of the LTFS format specification go to: Linear Tape File System (LTFS) Format Specification.
The system brings a new level of portability and interoperability to open-systems tape storage.
