syncing a whole directory down

[szabgab]

I'd like to be able to connect an external hard-disk to my computer and sync all the content of my Dropbox (or just a specific folder) from the cloud directly to this disk to have my own private backup.

Later I would like to sync again with an operation that can take into account what I already have on my local external disk so not to download all the files again.

Is it already possible with dbxcli? If not it would be really nice to have.

It does not seem like Dropbox developers are monitoring GitHub issues! :(
