In my office I have an external hard drive connected to my router. There are 4 computers in my office all hard wired to the router. I am trying to write a batch file that will: backup up all files and email initially, then only back up newer information. I don't know what type of files I should exclude. I have been told robocopy is the way to go, but i have never written a batch file before. I was told it was an alternative to an NAS server. Can anyone show me a mock up of how the batch file should look? And maybe some of the steps I need to do, from start to finish, to input the batch file? Any help would be greatly appreciated, thankyou!
