Magnetic tapes used to store copies of data, for use when restoration or recovery of data is required. Data on backup tapes are generally recorded and stored sequentially, rather than randomly, meaning in order to locate and access a specific file or data set, all data on the tape preceding the target must first be read, a time-consuming and inefficient process. Backup tapes typically use data compression, which increases restoration time and expense, given the lack of uniform standards governing data compression..”
