I think this sits outside of the remit of dbFront. This is adding a database administration function into what is essentially a great development tool.
There is a danger of trying to make dbFront do too much - I'd say stick to the development aspects.
For the most part I agree with Colin. This is beyond the scope of what I had originally imagined should be dbFront's responsibility.
At the same time I have had occasion to setup multiple client virtual private servers and I have been surprised at how poor or expensive the default backup options were.
There is a pile of good server backup solutions including free or paid options. Linked is a list of some that I would personally recommend: Server Backup Suggestions
At the same time, if dbFront and a database are the only thing you care about on a server, then it would almost seem intuitive if dbFront could handle the backup functionality itself. Especially since dbFront already has the built-in ability to Export/Import databases.
If you feel this is valuable then please vote on this suggestion. If I get more requests or funding then I will definitely consider adding this functionality.
