With my HostGator account I do a daily backup of 25+ websites and 25+ mysql each day and download it to my PC - I have total backup.
However, during the day I need backups of new websites I bring up or before I activate a new version to a plug-in - I use this plug-in for that.
It's simple and fast and I copy the backup to my PC and then delete it. Sure it has some problems now that will be taken care of in a while but there is NO alternative for what I need during the day.
So use this plug-in to make fast backups of your entire website and move it to your PC then delete the backup - it works just fine.
