The inability to use the Airport Extreme to host the Time Machine drive for me means:
1) Forget Time Machine (and 10.5?)
2) Anchor my MacBook to a desk
3) Buy another Mac.

Since it was listed as a feature until recently, I'm hoping that there was just a bug with it and that they will reintroduce it when they have it fixed.

Did you say whether Time Machine saves files using the original file extension linked to the program that created it or is it an Apple proprietary file system?
It's pure HFS+. You can even browse the TM backups directly in the Finder.
"The implication is I could search for all the pdf files backed up by Time Machine and pull a copy of one for use on a flash drive for transfer to another computer."
Spotlight in the Finder won't search the TM drives, so you can't find them that way. And Spotlight search within the Time Machine interface will find the newest copy of whatever you're searching for.
You could use Terminal to find and copy every version of a file, I guess, though I haven't tried it.
"Did you say we could key word search all the files in Time Machine?"
Key word searc? You can run Spotlight searches on either content or file name from within the TM interface, but that won't show all backed up versions of a given file.

So what about backing up encrypted disk images? After reading the recent Macworld articles on security I created a disk image with all my financial info that I want to keep secure. That disk image is on the hard drive of my PowerBook. As I understand things, the disk image appears as a separate drive once it is mounted and, I presume that Time Machine would back up any changes I make when the disk image is mounted. Will the backups be encrypted? And what happens if I mount the drive, do some "financial stuff", and then dismount the image before the next hourly TimeMachine backup? Will the encrypted .sparseimage file be backed up by Time Machine or does the image have to be mounted for any changes to be backed up?
Thanks,
- Scott

Time Machine backs up files, not volumes per se. Time Machine won't see the mounted volume as something it backs up, in other words. It will back up the DMG file itself. So anything you place on it will be backed up, in the sense that TM will grab a copy of the disk image.
But if you want to restore files off the disk image, you'll have to restore the whole image. So yes, the backups are encrypted, because it's simply backing up the disk image file.
Files on disk images, best I can tell, are not backed up individually. Just the enter disk image.

I'm confused about the "no AEBS" issue. Apple forums seem to think it is doable albeit with known volume header corruption issue making it less than desirable.

Any thoughts?

Rob, I habitually use "secure delete" when deleting files, both on my Internal iMac HD and the External Mirrored RAID HD where I keep 100% of my media (documents, iPhoto's, iTunes, Movies, Videos, etc.). Will this practice have any adverse effect on my TM dedicated drive?....In other words, even though I securely erase all files and media on my internal and external working drives, there will still exist backup copies on TM, correct?....Thanks

Thanks Rob. If that's the case, I guess that's good motivation for getting a large backup drive. If Time Machine is going to back up the entire disk image (52 MB at the moment) every time I add a 100 KB account statement, it going to eat up space in a hurry.

Will Time machine be able to use more then one external drive for it backups?

I'm angry. I bought an Airport Extreme recently in anticipation of using Time Machine with an Airport Disk. I still have other reasons to own it, but Time Machine was a major factor in my decision. If I would have known, I probably would have bought a cheaper router for a better value. Thanks, Apple. /forums/ubbthreads/images/graemlins/mad.gif

That's why Apple put the fine print on their web site: "Features subject to change without notice"
Also, consensus seems to be it will work when the AEBS has a fix for the drive sharing feature.

[griffman]

As long as you don't delete something from the TM backup (which I think is somewhat tricky to do, actually), then yes, it should be there. It won't, of course, be on the newer post-delete backups, but anything prior to the deletion date will exist (as long as you have the drive space).

Here's a question I've been trying to get an answer to:
Apple tells us that they will rollup the hourly snapshots into a single daily one. Similarly they will do the same for other time periods, but let's just stick with the hourlies.
Now, say you have created a file (call it mywork) and made changes over 3 hours and then deleted it. Thus you end up in TM with the equivalent of 3 files in TM, mywork(1), mywork(2) and mywork(3). If you go back in time while the hourlies still exist, the Finder will present you with each of these files in their respective time frames and call them just mywork.
Now, however, we reach the point where the hourlies are rolled up. What happens when you go back in TM to that day?
1) TM keeps ALL versions of the file and you see mywork(1), mywork(2) and mywork(3) in your folder.
2) TM keeps the last version of any file that ever existed in any hourly that day and thus only mywork(3) shows up on that day (named, of course, just mywork).
3) TM removes any file that does not exist in the final hourly for a given day. Thus, when you go back there is no file there.

Here's a question whose answer will probably have to wait for Leopard to arrive: Since TM supports backing up to a drive shared by a Leopard-ized Mac, will it work on my local network and via Back To My Mac? I know a TM backup over the Internet would be really slow, but it'd be nice to have the option.

I see Time Machine as part of the overall answer. I clone my drive regularly, so when my drive dies I'm up and running pretty quickly. At the same time Time Machine will come in handy for those times when I delete a file only to realize I shouldn't have. I don't think Time Machine will replace the cloning of my drive but more complement and enhance how I backup.

I'm curious about this as well. Having an external hard drive anchored to my desktop is obviously not a hug issue, but there ain't no way that's gonna work for my Powerbook G4, so the plan I had in mind was to partition the internal 80GB hard drive into 50gb/30gb (or something like that, I haven't decided on the exact partition sizes), and use the smaller partition to do hourly back-ups of just my documents, then at home I would be able to mount a shared partition from my desktop to do a fuller daily/weekly backup.
For those in the know, does this sound like something that would work?
