backup files to dropbox without sync directories

Question

I would like to backup some files on a remote machine (Ubuntu 20.04.6 LTS)  to my Dropbox, avoiding creating a sync folder. Hence:

* using the command line (GUI not available)
* without creating a sync folder (I don't have enough space on my disk; files are now on an external HD connected to the remote machine)

The Dropbox daemon is installed and updated to the latest version:

Dropbox daemon version: 190.3.6262
Dropbox command-line interface version: 2020.03.04

however, it seems it does not have anything like upload.

Moreover, I wonder if it is possible to backup files to the remote desktop from a machine that does not have the daemon either (such as an HPC)

Thanks,

Cesare

Hi @Cesare Corrado, thanks for messaging the Community.

Currently, this wouldn't be possible without a local folder to sync files from.

You might be able to create an app using the Dropbox API to achieve what you're looking for.

If you have any further queries, feel free to message back.
