Automating Tape Backups: Page 2 of 5





Spec it Out



Autotape Loaders

If you expect to buy extra capacity to accommodate your projected data growth, we encourage you to question the manufacturer on the reliability of its pass-through mechanisms, which can often pose problems.

Ask about jam and failure rates. The more drives you stack, the faster your backups. But more speed doesn't necessarily mean more capacity. Extra drives let you shorten the backup window, but will not significantly increase the capacity.

Here, again, the five-year model can serve you well. If you aren't sure the unit you're considering can be complemented with a reliable pass-through mechanism, get enough slots in the original base chassis to accommodate your projected five-year data growth. But be certain any backup software you use is certified to work with the autoloader you purchase.Buying an autoloader isn't like buying a toaster. The physical environment in which you set up the equipment is just as important as the product's capacity and speed.

Most autoloading products take up no more than 20u. Unless the space at the installation site is tiny, most autoloaders, even some of the higher capacity units, should fit.

Be sure the equipment you purchase will meet your configuration needs. If you require a rackmount configuration and the vendor only sells freestanding, you have a problem.
