I recently picked up a Drobo for storage and light backup, and want to clear the 1TB Western Digital external drive I have off my desk. I would like to still use Time Machine, but possibly off a share from my Airport Extreme, so my wife can use it on her laptop too.
This disk currently has been running Time Machine locally for my iMac. If I move the disk to the extreme, and tell Time Machine to use it - will it just start off from where its at, or will it have to do an entire new full backup and start over again?
And with that, can you have multiple machines backing up to the same disk shared through an Airport? Or should I partition it for the different machines using it?
