Implement a backup/restore solution

[chiruzzimarco]

We need a way to easily backup and restore project data.

This feature should prove useful for:

• dumping data to a specific (maybe configurable) location in a compressed format, ready to be synched to an external storage. The synching of data with external storages is currently out of derex scope.
• allow for quickly backup/restore operations between different environments (e.g. i want to quickly move production data on my local environment)
