I have 2 servers not on a LAN. They are both on the Internet. I need to have the data folder on server A update with Server B. Whats the most reliable trustworthy method to use? Im thinking maybe PC Anywhere, or maybe FTP server and schedule the client to upload files not present on the target. Ive tried this about 4 years ago but didnt find something that I could depend on. Sometimes it would sync, others not. Also Im concerned that if the method is by looking at dates of files, what if the target comp gets time messed up and all the files are deleted on both machines?
