Looking forward to testing this out and seeing it in action!

I hope we can switch out Dropbox for another provider easily?

yes its possible to use another provider.

Just replace:

dropboxbackup(filename=fileparam, host=nodename)

with whatever service you desire.

Otherwise you can use this code as it is. I've graduated this snippet to an actual repo to work on it more and track changes better.

Plans is to refactor and write some tests, and then include it with noma(1)
