If you have data files that are updated frequently to change a small percentage of the data in that file, Time Machine will copy the entire file, taking up more space on the backup disk. If, instead, you can separate the volatile data into a smaller separate file, Time Machine will be able to back up changes to the smaller file and make more efficient use of backup disk space."Google is your friend. http://developer.apple.com/leopard/overview/apptech.html

Maybe Apple's one works in a similar fashion. well, there (@ least were) a few utility programs that provided the same function. Maybe Apple’s one works in a similar fashion.

IOW, the full copy is the latest version, and older versions are sparse representations. It's about the same thing you'd do with Rsync if you thought about it a while before implementing your backup script.HTH TimeMachine starts by making a full copy of the volumes you want to keep backups of, and then makes reverse-deltas peridodically.

I may have dreamt this, but I seem to recall someone fairly official saying that the optimal method for Time Machine is to have an external drive dedicated to act as a mirror. My hunch is that this will not be a typical mirror, but one that will update itself while also keeping a certain number of drafts of a file, allowing one to choose which version of a lost file they wish to recover. That being said, I can't imagine Apple would tout TM as such a great feature if one were required to have a dedicated, second drive. In the absence of such, I imagine TM will utilize some space on the boot drive. In any case, I’m glad to see apple building a backup strategy into the OS, as I’ve seen far too many friends/clients lose crucial data because they didn't backup. So all in all, I’d say TM is "A Good Thing.™ I haven’t read any official docs on this nor have I played with a beta version of Leopard, but I think the Time Machine will basically be a slick GUI under which a mirrored hard drive keeps track of things.

I think that it keeps track of the changes, but it would obviously need the extra space for that and to keep one copy of the original file. So I have changed my mind. In fact, I have had a brainwave.

The requirements state that an formatted drive or partition will be needed. But, it doesn't say whether it will keep a full copy or just the changes. I would personally say that it will keep a full copy, from the requirements.lamboman - dalambomanblog.blogspot.com At the moment, it looks pretty unclear as to what Apple will use.

You can just hang a USB2 drive (say, LaCie's Really Big Disk, or something like that) off an AirPort Express, which will share it over the wireless network, and back up to that.

That said a change file would be a good way to save space and provide the functionality. Keep track of File changes, not the whole file. Thus if I have a 10 gig file and I change 1 gig of it I save the 1 gig I changed not the whole file. Time Machine
