Continuous, source/destination selectable, time-stamped backup: WonderSave?

Question

I've spent a significant amount of the last six years (5000+ hours) in front of my Mac putting together a book. I'm very careful about backups: documents are saved several times an hour while working on them, then backed up twice daily to five hard drives in rotation, then weekly to two sets of DVDs. Never lost an ounce of work -- until yesterday. Something happened to several of the documents I was working on before I did a backup. They all had a size of 0 bytes, and when I did backup...
In two hours redoing the work, I had the documents back but was I annoyed at the waste of time. So I need a piece of software which I am naming WonderSave. This is how it works:
*Step 1*: I fire up WonderSave and it allows me to select any area (the Source) on any of my hard drives that I want WonderSave to keep an eye on. This selection process is similar to how I can select multiple areas when using OSX to Find.
Step 2: I select where I want the backups to appear (the Destination).
Step 3: I tell WonderSave how long to keep the files before deleting them.
In operation, every time I save into my Source, WonderSave simultaneously saves a time-stamped copy in my Destination. For example, if during the day I work on 15 files in four different programs and save a total of 67 times, I will find a have 67 files in my Destination.
Gladden my heart, someone, by telling me the real name of this wonderful piece of software.

Answer 1

No, not the ones I mentioned. You could upgrade to Leopard and use Time Machine which does backup every hour. The ones I mentioned can be scheduled to backup as frequently as you want, but this imposes some overhead for constantly checking the drive for changed files. Not overly efficient.
There are two backup programs that do that, however, called TimeDrawer and NTI Shadow. They do not create bootable clones, but they do perform versioned backups as you describe. You will find them at VersionTracker or MacUpdate.
There is no backup solution that does everything. You may need to implement more than one to accomplish both automatic backups when a document is saved and create bootable clones. For the latter there are some good alternatives:
LaCie's new SilverKeeper 2.0 (free)
SuperDuper! (commercial)
