Just my two cents. It is not a backup. It fails on a few tests which are simple. No write protect switch and and a virus/trojan/spyware/other can easily infect/destroy the information on this drive.
It is, in fact just a second copy and not a backup. A backup would be readonly so when you go to restore, if a virus/other was at play then it would survive.
Nice idea, but it is flawed from the outset.
I was really excited with the prospect of getting a Maxtor or Western Digital One-touch type back up system for my P.C. Just simple, regular backup of files, nothing special. However, the reviews I've seen of the actual software (Dantz Retrospect and others) associated with these one-touch systems look pretty problematic/horrible. I was wondering if these systems are as much of a problem as they sound, and if so, what is another option? Buying a regular external hard-drive and a different backup software (if so, which one!?!?!), or just getting a hard-drive and doing a simple drag and drop (although usually rather time consuming on my part)??
