  • Is Tape Backup Dead? We Expose the Common Myths and Rumors
    Backup for the Rest of Us Is Tape Backup Dead? We Expose the Common Myths and Rumors. Trust NovaStor DataCenter for Fast, Reliable Data Security Introduction People have been proclaiming the death of magnetic tape for decades. There is a recurring tendency in some IT circles to declare backup to tape as obsolete or near death as ‘the cloud’ increasingly makes its way into the data centers of the world, as a backup destination. But even in these times of private cloud services, SAN snapshots, SSD’s, and cheap public cloud storage we shouldn't be too quick to lower the coffin. The rumors circulated by cloud service providers and disk vendors mighty have you believe that tape is slow, unreliable, or simply outdated. Perhaps you even have a personal experience, where a poorly implemented system was inherited or you got stuck using archaic backup software. Whatever the reasons, if you have preformed opinions, we ask that you temporarily suspend them as we tackle the most common misconceptions surrounding tape as a backup medium. Tape does not fit all situations and may not be the ultimate storage solution, but it may still have a few tricks up its sleeve when it comes to the long term retention and archival storage of your critical data. Today we tackle some of the most popular, and highly circulated myths about tape. Supported in the USA www.novastor.com 02 #1 Tape Is Dead Whoops, who said that? A global survey conducted by Kroll Ontrack in 2017 showed that while cloud storage use had doubled over the previous year, magnetic tape has also experienced an impressive boost in popularity.

  • Digital Linear Tape (DLT) Technology and Product Family Overview
    Digital Linear Tape (DLT) Technology and Product Family Overview Demetrios Lignos Quantum Corporation 333 South Street Shrewsbury, MA 01545-4112 +1-508-770-3495 [email protected] Introduction The demand that began a couple of years ago for increased data storage capacity continues [1]. Peripheral Strategies (a Santa Barbara, California, Storage Market Re- search Firm) projects the amount of data stored on the average enterprise network will grow by 50 percent to 100 percent per year. Furthermore, Peripheral Strategies says that a typical mid-range workstation system containing 30GB to 50GB of stor- age today will grow at the rate of 50% per year. Dan Friedlander, a Boulder, Colo- rado-based consultant specializing in PC-LAN backup, says “The average NetWare LAN is about 8GB, but there are many that have 30GB to 300GB.....” The substantial growth of storage requirements has created various tape tech- nologies that seek to satisfy the needs of today’s and, especially, the next generation’s systems and applications. There are five leading tape technologies in the market to- day: QIC (Quarter Inch Cartridge), IBM 3480/90, 8mm, DAT (Digital Audio Tape) and DLT (Digital Linear Tape). Product performance specifications and user needs have combined to classify these technologies into low-end, mid-range, and high-end systems applications. Although the manufacturers may try to position their products differently, product specifications and market requirements have determined that QIC and DAT are primarily low-end systems products while 8mm and DLT are compet- ing for mid-range systems applications and the high-end systems space, where IBM compatibility is not required.
