I use Handy Backup and I swear by it.. I think you can use a demo before you purchase... then the purchase is 30 bucks if I remember correctly.

With Handy Backup you can do many forms of backup to the same computer, to another computer on the network or to a remote ftp. I have it set up so that one computer has a 400g raid set up. Everything from all of my other 3 computers backs up into this box. I have it on incremental backup meaning the first time its run it backs up the whole drive.... but the second time it only copies new or updated files. After you run the first main backup which takes a long time as it copies everything.. the next backups take minutes as it only coping a few new files.. You can also back up single files or single directories instead of the whole drive. You can set it to back up automatically at any interval... Hourly, daily, monthly... time of day... etc... .... I also just like the interface....

The only thing I'm not protected against is if my shack burns down or if ALL my computers were stolen at once. The ultimate solution is offsite storage.. Like to a ftp (which Handly backup can also do). That’s a pain in the ass though.

As far as passwords.. I always use a password for windows I use passwords for financial stuff like quicken.

Peace
