How To Move OS X Time Machine Backups To A New Disk
Well, that happened pretty quickly! After upgrading the internal hard drive on my MacBook Pro to 320 GB, I moved the 120 GB disk Apple shipped with the machine to my Verbatim SmartDisk FireWire+USB enclosure to use as a Time Machine backup target. Despite applying some tricks to reduce the amount of data backed up by Time Machine, I filled up the 120 GB drive pretty quickly indeed! So I decided to swap the 160 GB drive from my Maxtor OneTouch 4 Mini USB drive into the (faster) Verbatim FireWire enclosure to give Time Machine some (temporary) breathing room.
It turns out that you can move Time Machine backups easily, with included OS X tools, and without breaking anything. My old backups are still visible, and I have another 40 GB to work with. Read on for the details!
