Backup your iDisk to CD using Apple's Backup Internet
If you are a .Mac subscriber, you know that Apple's Backup utility will allow you to back up data to your iDisk. However, if you've ever tried to back up your iDisk to a CD, you'll find that Backup will tell you that it cannot backup remote volumes.

Well, under Panther, it is now possible to back up your iDisk if you have automatic syncronization on. To do so, tell Backup you want to add a new item to backup. Navigate to ~/Library -> Mirrors -> SOMETHINGRANDOM -> YOUR_.MAC_USERNAME.dmg. Backup will happily burn this file to a CD, and you will have a complete backup of everything on your iDisk. Backup will remember the location in the future, so you only have to do this once.

I finally realized that the directory name, which appeared to be random, is actually the MAC address of your built-in ethernet card.

I suspect this might be a mechanism for .Mac to keep track of the Sync status of that particular machine. But I'm only guessing.

That's very cool. I just wish I had thought of it!

Wow, who thought this would happen?

It's a 100 MB disk image though, even if you have less than 100 MB in your iDisk.

It would be really nice if Backup would just let you back up the iDisk...

How does Backup compare as a general backup program with other stuff that's out there? I was looking at the .Mac info a while back and it mentioned being able to use Backup to back up stuff on your local computer, which seems useful to me, but I wasn't really interested in getting .Mac just to see if I liked the Backup program itself.

Backup your iDisk to CD using Apple's Backup

In poking aroudn ~/Library/Mirrors/xxxxxx/ directory, I noticed a file called mirrors.plist. I always like to poke around inside plist files to see what kind of info each app is storing.
There's a property called "isHomeDirectory" which is boolean in the plist file. Mine's set to "no" which makes sense. But does this mean that Apple may be planning on allowing the use of an iDisk as home directory (obviously a mirrored home directory with "auto-synching")? I'm not sure what other functions the "Mirrors" directory may serve so this could have something to do with networked home folders, or even file vault for all I know. If anyone out there is using either of these then give it a peak. If you have the Developer Tools installed, just double click the .plist file and check it out.

Backup your iDisk to CD using Apple's Backup

So, how do you restore? I'm still using backup as I've really found TimeMachine to be beta at best. I have a backup plan that copies the Library/FileSync/random/macname_iDisk.sparsebundle into the backup image. However, when I restore that file, the OS recognizes it as a folder and not a sparse bundle with subfolder Bands and likely the disk image separated across the bands.

How can I repackage that folder to appear as a sparse image?

Thanks in advance.

Tim, I've found that the ~/Library/Mirrors/xxxxx/myname.dmg takes up a lot of valuable space on my hard disk. So I dont' use "Auto-sync". In fact, I've found it easier to use an external disk drive and third-party software, like ProSoft's Data Backup utility. I can create a "clone" of my hard disk that allows me to restart from the clone, and then, if necessary, I can create a clone backup of it back onto an initialized internal disk drive. That's better protection than can be afforded by a .dmg file. It's a personal choice.
