Backup to the Dropbox directory on the server without downloading the rest of the files?

Question

linux

I have an account on Dropbox, I have a server.
I want to backup files on the server to the backup directory on the Dropbox account in the root of the Dropbox directory.
I tried using the instructions on the Dropbox website and installed the console daemon. He earned. He gave me a link for binding, and then downloaded all the files from my account and to the server.
Hence the question:
How can I organize a backup so that the files that I use on my home computer are not downloaded to the server (they are not needed there and take up a lot of space), a separate subdirectory is synchronized - backup, for example.

The option with another account will not work for two reasons: my account is already pumped to the fullest up to 12 gigabytes and I don’t really want to pump the second one and rummage through folders with mine there, well, this is a crutch.

Well, yes. The server is on Linux, if someone hasn't guessed yet.

Answer 3

Great, thank you. It is a pity only it is necessary to store the login-password on the server. In the case of the DropBox daemon, a link for linking is issued and the account data is not burned ...
