What role should play a tape backup storage in a backup system? To reply that, first we have to talk about the streaming nature of tapes. Tape drives are generally designed to go extremely quick, and when they are not run at that pace, they don't perform as desired. For instance, an LTO-4 tape drive has a native transfer rate of 120 MBps. If you consider that most open-systems environments average 1.5:1 compression, which means that effective throughput of an LTO-4, is 180 MBps, yet extremely few environments run their tape drives at this speed. When you use a 180 MBps tape drive to write a 30 MBps stream, or even an 80 MBps, it spends a great deal of its time going back and forth (backhitching, as it is called) to keep up with that slower data rate. If it backhitches a lot, we call it shoe-shining, simply because the actions with the tape wheel imitate that of a individual shining his shoes.
Tapes must be encrypted if you send them outside. There are a number of choices, such as repeating deduplicated backups, continuous information protection (CDP), and near-CDP, but make it suffice to say that the three rules of encryption are key administration, essential administration, and essential management. Losing your keys is losing your data.
Getting the right tape library takes homework. An expandable, modular tape library supported by sophisticated administration features and tied to modern backup software will support your enterprise for years to come. It's worth taking the time and effort to make the proper option for your disk backup solutions.
