Enhancement: Allow local-only (on the filesystem) backup destination

[ernstae]

I would like to use this software locally only, but am not able to deploy SSH keys for connecting back to localhost in a particular scenario.

Since it's already implemented to have a local copy saved, would it be possible to enable a local destination as a primary location (rather than s3 or ssh)?

I did start hacking on this, and hope to submit a PR, but wanted to open it up with the off-chance that a better coder might tackle it before I can.

The local copies right now are implemented in a modifier class. If the local copy is the final destination the LocalDestination should inherit from PeriodicCopy (currently the development is going in the develop branch.). The implementation should be straightforward.

Meanwhile, I'd suggest you to setup SshDestination to 127.0.0.1. You can check examples in the vagrant configs - for tests we do exactly that in vagrant.
