backup to External hard-drive moved to new Time Capsule
I have been backing up one of my MacBooks to an external hard drive attached to a 1st Generation Time Capsule. I recently bought a new Time Capsule and plugged the external hard drive into this new Time Capsule.
I renamed the Time Capsule (but not the external drive) and didn't realize that this would stop my Macbook from finding and recognizing the external drive that it's always successfully backed up to. It seems to be using the Time Capsule name as part of the file path and therefore can't find it's way to the same old drive hooked up to this new TC.
Is there a way to point my Time Machine backup to the external drive that's attached to the new TC and have it automatically resume backing up (without starting fresh)? Or do I need to rename my Time Capsule so that it exactly matches the old name.
I hope this makes sense. I just don't want to have to start a fresh/new backup.
