After several hours of research and several demo installations, I finally found a good - inexpensive backup software. SyncBackSE from 2BrightSparks has been working well for me on my web server for the past couple of months and I've just installed it for a client to make backup to their network hard drive. The software handles FTP and Network drives without any problem and is relatively easy to set up and schedule. I'm using it to make a daily backup from my web server (Intermedia) to an application server that I rent (Aplus) at another server farm. I also do a nightly backup from the application server back to my web server. This gives me off-site copies of critical files on both systems.
