I don't get how time machine works.. Do I have to use a special Apple external harddrive thingo or can I use anything?
any hard drive formatted in HFS will work greatthe general thing is to try get a HD that is 1.5times larger then the disc you will be backing up - gives you more space and stuff..
(dont go LaCie haha)
Time Machine saves the hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for everything older than a month. You can also tell it which files to exclude (things like certain caches, virtual hard drives, etc.,).
My own rule-of-thumb has been 1.5 to 2x.
For the OP: The more space you have available, the "further back in time" you can go. The amount of time, of course, depends on how many and how large the files are which change.

Oh cool, thanks everyone makes sense now. Why would you need hourly backups for? I get weekly and monthly but not hourly, it would always have to be plugged in (the external harddrive that is)
Time Machine is essentially a glorified version backup scheme. In other words, every other or so, your machine is backed up and becomes, say, "version 1." The next hour, the next backup becomes "version 2," etc.
Over time, you build up a lot of backups and thus can go back as far as possible to recover any deleted data.
fair rule, makes sense really. especially if you are changing a document(s) quite frequently.
personally i HATE the automatic backup. im not in a situation where i need to bring back files from 20 minutes ago (i dont make changes to documents, if i do then i will save it under a different name). i manually backup, it saves space and time. my backups are mainly performed before i update the OS to the latest 10.5.* versions.![]()

I have both Time Machine and bootable image backups (regular, sorta). As for the automatic hourly - originally, I was against it. But, it's so seamless I figured I'd give it a try. Just yesterday, I had some syncing problems with my iPhone and needed to go back to the iPhone's backup from before I had the sync problems (iTunes was removing apps apparently because it felt like it, but that's another story). All I needed to do was open the Backups folder, go into Time Machine, and roll back to an hour where I knew I had a good backup (it was just the previous iPhone backup from a sync earlier in the day). In about 10 seconds I had replaced my newly inaccurate backup with the good one and was on my merry way restoring my iPhone.
If I had only relied on backing up only my own data and periodically doing the image backups of the complete drive (they are time consuming), I would had a much older copy of the iTunes backup and not felt as confident using it (it would have worked, but how much recovery after would I need to do manually?)
For the ridiculously low price of drives these days, why not do both? Also, Time Machine is zero configuration (except for some fine tuning later with exclusions).
1TB externals regularly around $90 (USB2). Even the 1TB Dual FW800 Seagate Freeagent Desk Mac has been $139. That for Firewire 800, too.
To backup a 320, a 750 is plenty, but I have 600 set, and the rest for an emergency boot volume, and some secondary media storage. I do have the Freeagent FW800 1TB, but that's going to be video work and other media only. It's a great deal, though - quiet and very fast on the FW800. Sorry - good a bit side tracked... Ooooh. Shiny!![]()
You have no doubt not encountered a hard drive failure or stolen equipment.
to backup all of my data wouldn't be cheap.
SO it's a good idea to enable it? Or just back up another way?

When I work at my desk my external HDD is always plugged in and I just let Time Machine work in the background. And it backs up as soon as I plug in my MacBook if I happen to of been using my MacBook away from my desk.
Not even compared to losing it when (not if) your HD dies?
Maybe most of your data isn't worth much?

Why not if you don't mind me asking? I'm looking to get one that has both Firewire 800 and USB compatibility and I've read pretty good reviews of the LaCie.

I have the Seagate FreeAgent Desk Mac FW800/USB2. Fry's has had it for $139 over the last month or two. Very quiet and, of course, fast with FW800.
In general, I try to go for the drive with the least amount of features for my Time Machine backups. A lot of drives offer fingerprint security, Ethernet support, wireless backups, but all I want for a drive that is so critical is just the ability to store files, and store them reliably.
I also recommend that people don't just rely on a Time Machine backup. Time Machine is an excellent tool to use for "oh crap" stuff, be it accidentally deleting a file, erasing a hard drive, or whatnot.
