Edit: But then I looked at syncthing's git repo and thought, nah!
At the moment I'm paying for SpiderOak, which does this but another open source alternative that's getting there is Syncany[0], which supports a variety of cloud providers through plugins, versions all files and encrypts data.
There's also git-annex but its plugins aren't always high quality and usability is... Challenging.
With 800GB of data, I can send it to:
- SpiderOak: $130/year (1c/GB)
- Google Drive: $10/month (1c/GB)
- Dropbox $10/month (1c/GB)
- OneDrive $7/month (1c/GB)
- Amazon S3 $24/month (3c/GB)
- Google Cloud Storage $16/$8/month (2c/GB standard or 1c/GB Nearline)
- Rsync.net $160/month (20c/GB)
And that's not even taking the backup providers into account.
I definitely see where rsync.net would shine for business users because it looks like you have great support but for a regular guy who wants to backup his few hundred GB of photos and sync some files it doesn't make much sense.
