Time Machine Question

[lamina]

Why can't I backup with Time Machine initially over USB, then do it wirelessly? My backup is about 97GB, and that would take unacceptably long over our G network, even if I did it overnight.

So, I've done the initial backup via USB, but when I have the Time Machine drive plugged into the USB port of the iMac, it will try to do a new backup via a sparse disk image. The USB backup is its own folder.

Any ideas? I would really love to get TM working over wireless again. I did it before with my PowerBook, but that backup was significantly smaller.

I'm assuming you meant that you were plugging in an external drive first via USB on the iMac then on the USB port of the Airport Extreme? You didn't mention about the Airport.
If you are connecting wirelessly through the Airdisk only Time Capsule has the ability to plug in directly to the iMac for the initial backup then wirelessly after that without creating a new Sparsebundle.

Apple has not officially announced support for Airdisk and at this point this may be one of the features of the Time Capsule that separates itself from connecting an external HDD via Airdisk.

Hi,

I think this will help you.

Hope it does.

Thanks for the replies.

I just plugged it in, let it do another backup, and it backed up to the sparse image. Works over wireless now. There's no airport involved, just a regular wireless router connecting the iMac to my MacBook. Works great now.

Thanks!
