Figure 1-3 3584 Tape Library Then the amount of data being backed up grew exponentially, and different types of data required different backup and recovery methods. Bandwidth utilization became more of an issue with the use of super drives, such as IBM Linear Tape-Open 2 (LTO-2), LTO-3, and IBM 3592. These super drives rely on the ability to stream large blocks of data. Some data requires a long-term archive, while other data is needed immediately upon request. The tape library remains the long-term archive device to safely and inexpensively
