I've been using an external hard drive on my MacBook for time machine for a year or so. Now I have a Mac Mini too and have connected the external hard drive to that for the same purpose.
I want to leave it connected to my Mac Mini and still backup to it wirelessly from my laptop.
I have done all the steps to allow time machine to recognise network drives and I can see the drive from my laptop etc., but it won't recognise the old backups.
Do I need to change the file permissions or similar to get it working?
