In computing, off-site data protection, or vaulting, is the strategy of sending critical data out of the main location (off the main site) as part of a disaster recovery plan. Data is usually transported off-site using removable storage media such as magnetic tape or optical storage .
The IBM 7340 "Hypertape" system was a magnetic tape data storage format designed to work with the IBM 7074, 7080 and 7090 computers that was introduced in 1961 and withdrawn in 1971. As a technology, it deviated in several ways from the then dominant IBM 7 track system. It distinguished itself by having higher capacity, faster data transfer ...
Stand-alone tape management systems are predominant on mainframe platforms where tape is used as both a backup and base load storage medium.. Mainframe systems such as IBM's z/OS do provide some basic support for tape inventory control via the OS Catalog but as cataloging files is optional it is usually required that an additional software package does the following:
Actual user data is managed via a cascading hierarchy of storage media (Primary Storage Pools) presented as raw devices (UNIX), filesystem containers (Windows and Linux), streaming tape or optical media. Additionally, emulated tape from a Virtual Tape Library or EMC Centera WORM archival device is supported. Duplicate copies (backup sets or ...
At the end of the tape, the drive reversed the direction of tape motion, moved the read and write heads slightly vertically across the tape, and continued to write (or read) more data until the beginning of the tape was reached. This process could be repeated many times, laying down several track sets on the tape media in a serpentine recording ...
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of 7-track , later 9-track tape.
