I just went through a long and complicated process that started when my apartment was burglarized and my laptop was taken, through getting a new laptop, replacing that harddrive and restoring from a backup of my old laptop. After all that, I hooked up my new laptop to the time capsule and restored everything via ethernet. I'm now using my TC as a network extender for the house, i can connect to it and see the files in there, but when I try to set up Time Machine to use it, it starts backing up my entire laptop all over again, which apparently would take 48+ hours over wifi. I'm guessing that when I set it up earlier and made the backup, it was over Ethernet. Now, it can't find the time capsule over ethernet, and thinks that the time capsule via wifi is a new source. Is there any way to select a time machine file to use and update? I'm using a 1st generation 1 TB Time Capsule with an uMBP 13", 10.6.5. All software is up to date. Any thoughts?
