I am using a freebie called FTPSYNCH to work in conjunction with this.
It FTP's from my PC into the website twice daily, just after the cron backups happen. (6am and 6pm) It synchs the local folder with that of the server's backup folder, effectively downloading just the sql backup created a few minutes earlier.
In addition to this, i have it doing a sql single file download once daily (overwriting every 7th day, for day of the week), so there's always a 7 day history in addition to what this add-on provides. I am only using this add on for a once weekly comprehensive backup, file by file. The twice daily ones are a single file done with a command line cron command.
There may be better ways, but this works for me
