Hi Dennis,

This may help you with your evaluation

There is a very good article about backup strategies (including
comparason between various backup softwares) in Nov. 1998 issue of
SunExpert. If you are able to find a hard copy, you can go to
sun.expert.com and search "Legato network". You will be able to download
the PDF file of this article. I strongly recommend this artle.
