So I was wondering: can I move a Time Machine sparsebundle file from one location to another and have Time Machine accept it without complaint?
Short answer: yes.
Long answer: follow these steps:
- On the source machine, turn off Time Machine.
- On the Time Machine Server, move the sparsebundle to its new location.
- On the Time Machine Server, make sure the new location is a valid Time Machine backup destination.
- On the source machine, turn on Time Machine.
