What is LTO Storage?

LTO (Linear Tape-Open) storage is a magnetic tape data storage technology used mainly for long-term archiving and backup. It has high capacity, a low cost per terabyte and very high durability, and it is the industry standard for "cold storage." Unlike hard drives, tapes are offline when not in use, so they give you an "air-gapped" backup that is immune to ransomware and cyberattacks.

MrPlanB.com treats LTO storage as a proven option for data retention, especially for users with large amounts of data that doesn't need to be accessed often. Modern LTO generations (like LTO-8 or LTO-9) can store tens of terabytes on a single cartridge. A tape drive can cost a lot up front, but tape is reliable and long lived (often rated for 30 years), which makes it a strong choice for the final tier of a backup strategy.
