If you want a easy, reliable and cross-platform way to share files between computers, phones, etc, it may be of your interest.
This is one file at a time. It’s designed more for very quick “Oops I need that photo” sort of stuff.
What you want to do is better served by NFS, SMB or SFTP.
Synced many terabytes, over WiFi, Ethernet and the Internet with Syncthing. It works for all use cases, large and small.
When we are talking terabytes of data there are faster ways for the initial sync job.
I would just use rsync/sftp/robocopy or similar for that first copy for faster transfers, then setup Syncthing on those shares for delta syncs.
Am I allowed to think it’s weird the entire open source community can’t compete with SMB?
