Include backup date in 'backup filename'
This suggestion covers all products. At the moment when all the tables are backed up each table is backed up in to it's own file in a specific directory. So each time a backup is made it overwrites the old backup. That's fine but (as an example) what if you backup daily and something goes horribly wrong with the data for your site you can't roll roll back to the 'last good backup' because it probably doesn't exist if the live data got corrupted prior to you last backup.
I'd like to suggest that the 'backup date' be included in the filenam the same way vBulletin includes the date.
