I am looking for a way to synchronize an entire local folder structure to Amazon S3, similar to how one might synchronize two folders using Robocopy.
Whatever solution I come up with needs to be scheduled to run periodically from the Windows Task Scheduler. So anything that requires a GUI to perform the synchronization is not a viable solution.
Standalone Windows .EXE command line utility for Amazon S3 & EC2 looked promising, but seems to have been abandoned and would not work when I tried to use it. Possibly a difference in the way that security is handled now compared to that software's most recent release.
