Hello every one! I am looking for suggestions for sync software to use. I have an external 500 GB Hard Disk Drive attached to my MacMini, my surveillance software -running in this Mac- stores video files in this extermal drive, one file per day per camera, each file is around 500 MB, around 16 files per day. I need to copy (sync/backup) all this video files to my Synology NAS DS218j OVER THE INTERNET. The Synology NAS "Drive" is mounted in the Mac Mini. I tried using "Sync Folders Pro" sofware but it does not work for me. It hangs after a few files. Any suggestions on what software to use?
