If you can get the backups as dump files, have them sent to a Dropbox account or remotely to a server. Then install Backblaze or Crashplan on that server.

You end up with a Dropbox backup, server backup and a 3rd backup via Backblaze or Crashplan.

Cost is around $10/mo for Dropbox, $30 - 40/mo for a server if you go with OVH and $5/mo for Backblaze or Crashplan.
