SynbackSE - great product
I've been using Syncback for at least 10 years. I use the SyncbackSE flavor. The free version is great, but I have some more advanced needs. It's never failed me and has saved me countless times. I use it on 5 disks on my main machine as well as others thru my LAN. While it is highly customizable, new users can easily set up very powerful simple tasks and incrementally learn other features. The customer service is outstanding. If you don't understand something or have a problem, they will unfailingly work with you. I can't recommend Syncback enough
