Time Capsule Chosen as disk for Time Machine but storing Backups on Mac HD
Hello. Just bought a 2TB Time Capsule. I have it connected and working well with my ADSL router's wifi turned off. I use the 2TB HD for media and movies and have a 1.5TB External HD attached which is the chosen drive for Time Machine to backup to. The reason I chose to have the Backups to the USB-connected 1.5TB external is because streaming movies wireless from the usb-connected HD was a bit laggy, whereas from the Time Capsule 2TB was fine. Time Machine has been merrily whirring away since installing, no problems.
However, I just noticed on my MBP that it's showing as having 318GB of backups stored on the Mac internal HD. I've looked in 'All My Files' and there's nothing in there. On the desktop I have a 'Time Machine Backups' folder though. If I right click on this folder and 'show info', then it's some kind of shortcut to the 1.5TB external HD hooked up to the Time Capsule with the backups.
Why are these backups taking up space on my internal MBP HD? I have a MBA which is working perfectly, setup exactly the same way. It has 150MB of backups showing in the 'About this Mac - Storage' screen but that doesn't worry me. Any ideas greatly appreciated thanks :-)
