This is not a help topic but is a discussion about how you are using Syncthing. I am currently syncing a church archive that’s a little over 1.3TB to an offsite location. So far it’s been syncing (send only) over a week on a 15 megabit upload connection speed. It’s going to be done soon. How are you using it? Do you have an enterprise use case?
We are using it internally and have used it to solve a few issues with clients that needed data sycned.
I use it to sync a copy of my data between my Windows PC, to a Raspberry Pi with a 128 gig SD card.
