LTO (Linear Tape-Open)

As its name suggests, it is an open format magnetic tape backup technique. It was developed in the late 2000s by HP, IBM and Seagate.

Starting with LTO-3, the standard provides an additional feature for rewriting data, called WORM.

Since LTO-4 was released, the standard also allows data encryption and encryption key management.

Since LTO-5 was released, the LTFS partitioning functionality is available.

Some LTO formats

The LTO format has evolved over the years. Since 2000, more than eight different LTO formats were released. In order to read the content of LTO tapes, you need a drive which matches for the format of the tape.
