CAN THE COMING CRISIS IN BACKING-UP CORPORATE DATA BE AVERTED?
With the proliferation of networks and on-line storage
at individual clients on the network in large corporations comes increased
demand for back-up. What steps are companies taking to back-up this
critical on-line data. The next few stories, examine the problem and
some of the solutions being offered.
San Jose, Calif. market research firm, Dataquest, examined corporation
spending on desktop PCs, LAN/WAN, and mainframe computers. It found
in 1994 corporations invested 37.4% on desktops, 24.3% on LAN/WAN, and
38.3% on mainframes. This year the figures are 38.2%, 27.5%, and 34.3%
clearly indicating a large jump, nearly 3%, in LAN/WAN spending.
Last year Xephon, an independent market research firm located in Newbury,
Berkshire, UK, surveyed 474 members of IBEX, the IBM Mainframce Information
Exchange, a group of IBM customer companies. The survey examined a number
of issues of concern to information technology executives.
The study found that 75% of the data centers it surveyed were running
24 hours a day, with 58% running seven days a week. Over half, 53% of
the centers ran 24 hours a day, seven days a week. Nearly all, 97% backed
up their computers once a day. The average time for a back-up lasted
two hours and 34 minutes.
In addition, 88% of the centers backed up every week, a task that took
five hour on average. Finally, 57% of the centers performed a monthly
back-up that lasts five and a half hours. Notwithstanding what appears
to be a rigorous schedule of back-up, these precautions fail to meet
the back-up guidelines, published by IBM UK, Xephon asserts.
