A customer wants to sync some files (mostly xls-files) from 3 different locations. All the files must be stored locally at every location but every file has to be synced to the other locations at change. All the files must be at the same state at every location.
The customer doesn't want to use vpn. The files are at a size of approx. 0-15MB. There will be 2 (Windows)server and 1 NAS (Synology).
Is there any rsync for windows around? Does anyone knows a program which solves this requirement?
