Tape Backup Devices
Typical
backup drives connect via the parallel port, SCSI, ATAPI, or USB ports.
There are several different competing tape formats you should be aware of. QIC (Quarter Inch Format) is a format which either comes in a 3.5” or a 5.25” hard plastic case. It can store from 40 Mb to 25 GB worth of data.
Linear Tape-Open (LTO) is an open standard format developed by IBM, Hewlett-Packard, and Seagate. LTO was developed to provide a standard among normally proprietary tape backup systems. LTO format tapes come in a variety of sizes and types.
The positive of tape is a large amount of storage for a low reusable cost. The negatives of a tape are its access time – a tape starts at the beginning and moves to the spot where the data is when retrieving information.
Tape devices are typically only used for backup
situations.
