Traditionally, many businesses have done backup directly to relatively inexpensive tape systems. However, for many computer applications, it's important to have data immediately ready to be restored from a secondary disk if and when the data on the primary disk becomes inaccessible (for example, if the server fails). The time to restore data from tape would be considered unacceptable. On the other hand, tape is a more economical alternative for long-term storage (archiving). Because it's also more portable, tape is often used for off-site backup and restoration in case of a disaster. Disk-to-disk-to-tape is often used as part of a storage virtualization system. In such a system, data that is more likely to require restoration from a backup device may be kept on an on-site or off-site disk storage system; data, such as e-mail, that has less value over time, may be migrated on a set schedule to tape. The storage administrator can express a company's needs in terms of storage policies rather than in terms of the physical devices to be used. ____________________ RELATED TERMS: storage http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci214465,00.html?track=NL-34&ad=487365 backup http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci211633,00.html?track=NL-34&ad=487365 archive http://searchdatabase.techtarget.com/sDefinition/0,,sid13_gci211590,00.html?track=NL-34&ad=487365 tape http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci213091,00.html?track=NL-34&ad=487365 optical storage http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci966110,00.html?track=NL-34&ad=487365 storage virtualization http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci991633,00.html?track=NL-34&ad=487365 ______________________ SELECTED LINKS: SearchStorage.com's Maryann Tripp includes D2D2T in "The ultimate backup equation." http://searchstorage.techtarget.com/originalContent/0,289142,sid5_gci954355,00.html?track=NL-34&ad=487365 SearchStorage.com also offers "A resource guide for disk-based backup." http://searchstorage.techtarget.com/tip/1,289483,sid5_gci944882,00.html?track=NL-34&ad=487365 Targetfour is an example of a company that provides D2D2T solutions. http://www.targetfour.com/st/home/d2d2t.html ____________________ TODAY'S TECH NEWS: ATTENDEES VALUE CAMARADERIE AT CIO CONFERENCE Sure the golf was great and the advice was insightful.
