The industry standard for backing up your entire PDA -- programs, data, everything. Backup Buddy will back up your entire PDA and effortlessly restore it with the click of a button. Includes an Automatic Sync capability that allows you to specify the time for HotSyncs to automatically occur on a daily basis, thus ensuring that your PDA is completely backed up at least once a day. While it's simple to use and straightforward, there are also many customizable features. Invaluable tool and winner of numerous awards. By Blue Nomad Software.
Syncer http://www.palmgear.com/software/showsoftware.cfm?sid=52295720020903234800&prodID=44284
This freeware automatically syncs your PDA with your computer at the times and days you designate. Set it for the same or different times each day, and you can temporarily disable it, too. Very helpful tool to ensure that a HotSync gets done at least once a day to back up your data, download the latest news, or whatever needed. Freeware by Ryan Muller.

(TIP: Used in tandem with Backup Buddy above, you could ensure that your PDA is backed up twice a day rather than just once a day if needed.)
