So I made a home-brewed linux / raspberry pi time machine more or less like this. I ended up with time machine data stored on an ext4 partition shared via samba that was successfully recognized and used as a time machine backup destination my my mac. The drive holds 3TB of information, so it’s full of something.
But when I tried to use that drive as a source from Migration Assistant after my mac was wiped by apple repair, it won’t recognize the network drive.
So I bought another 6TB drive, formatted it as HFS, and copied the .pbundle / sparsebundle file onto it. I thought of this as a "nuclear" option sure to work.
But now, the mac still doesn’t see this new drive as a time machine source.
What should I do? How should I recover my data?
