XXCopy compared to RoboCopy
Feature Comparison: XXCOPY vs ROBOCOPY
Mac
PS: I've been using TechSoftPl's "MirrorFolder" -
MirrorFolder: A real-time folder synchronization and backup software - for years to keep folders in sync. You have to pay $39 for it and I could always have used a FOSS solution, but it's work faultlessly for me for years and I can't be bothered to change.
Gotta say that Richcopy hasta be the dogs bollocks for a Win environment.
