What role ought to 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 usually designed to go very fast, and when they're not run at that speed, they don't perform as desired. For example, an LTO-4 tape drive has a native transfer rate of 120 MBps. In the event 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. Whenever 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's known as) to maintain up with that slower information rate. If it backhitches a lot, we call it shoe-shining, simply because the actions of the tape wheel imitate that of a person shining his shoes.
Tapes should be encrypted in the event you send them outside. You will find a number of options, such as repeating deduplicated backups, continuous information protection (CDP), and near-CDP, but make it suffice to say that the 3 rules of encryption are essential management, essential administration, and essential management. Losing your keys is losing your information.
