What is LTO Storage?

LTO (Linear Tape-Open) storage is a magnetic tape data storage technology used primarily for long-term archiving and backup. Known for its high capacity, low cost per terabyte, and extreme durability, LTO tape is the industry standard for "cold storage." Unlike hard drives, tapes are offline when not in use, providing an "air-gapped" backup that is immune to ransomware and cyberattacks.

MrPlanB.com identifies LTO storage as a time-tested solution for data retention strategies, especially for users with massive amounts of data that doesn't need to be accessed frequently. Modern LTO generations (like LTO-8 or LTO-9) can store tens of terabytes on a single cartridge. While the initial investment in a tape drive can be high, the reliability and longevity of tape—often rated for 30 years—make it an unbeatable choice for the final tier of a robust backup strategy.
