•
How important is backup system reliability?
•
What will media cost (cost per gigabyte)?
•
Is the backup system supported by third-party software?
•
Is there a clear growth path for my backup system?
These are just some of the factors you should consider as you
embark on your quest for the perfect backup solution. If your data
backup needs are great and/or growing, and your backup window
is short or non-existent, as in many 7x24 operations, then an
industry-leading solution like DLTtape drives, autoloaders, and
libraries should be at the top of your research list.
DLTtape System Technology Details
To help you compare DLTtape half-inch tape technology to com-
peting technologies, let’s recap the features that make DLTtape
drives unique. DLTtape drives use half-inch tape in a single-reel
cartridge that eliminates wasted space. DLTtape media is drawn
Figure 11-1 DLTtape and Super DLTtape Drives
are the performance and
reliability targets for all others on the market today.
