Somehow I am doubtful that you can trivially build what dropbox does. I am on their pro plan, I have tried running Syncthing on my own servers but the cost is quite prohibitive. I have about 300GB of photos there. Some of the files change, sometimes generating quite a lot of space - e.g. I think calculating the deleted files it is quite possible that I have few terabytes of data at any given moment. I looked into getting that space on Digital ocean and it would be way more expensive. That is not including the price of my own labor, how much time would I spend on managing my own solution? Can I guarantee the same level of safety as Dropbox does? They have people thinking about security, I don't even have time upgrade my servers - beyond automatic update.. We did not even get into weird corner cases... Couple of months ago I was running some machine learning experiments and misconfigured the logging process and ended up with about 15m small log files in my dropbox folder. I had contacted the support and it was dealt with. Had I been using something like SVN I would have to manually purge the history or something like that. IDK, I am very happy for the value I am getting out of my money. For me the biggest value is that it works and I don't have to do anything about it.
