backed up. The figure is climbing at a much steeper rate than the rate of
tape shipments. Backup capacity must increase to match increased storage
demands in this and other categories.
With the projected amount of data that needs to be backed up climb-
ing at a rapid rate, and the projected growth in tape drive units shipped
staying relatively flat, each of those backup tape drive units must deliv-
er more capacity than ever before. Analysts project that there may be
the potential for a melt-down if the backup technology does not keep
up with that sharply rising demand curve. The continual evolution of
DLTtape technology and the dramatic increase in capacity and perfor-
mance delivered by Super DLTtape technology are a direct response to
this need. What factors are driving this rising demand for backup
capacity? Let's start with computer systems trends.
From Mainframe to Client/Server
The deployment of client/server systems is accelerating. From 1994
to 1996, the percentage of organizations that said they were actually
using client/server systems grew from 25 to 44 percent. Today,
client/server is the dominant mainstream approach to enterprise
