New MBP - existing Time Machine question

[markjewiss]

Hi there,

So I've just got a new MBP to replace my three year old model. I have a full external HDD with Time Machine backups on it going back in time. WHat I'd like to do is to have the new machine use the same disk for Time Machine backups, and to just carry on appending data - so that I can enter Time Machine from the new MBP, and see all of my old backups.

I haven't migrated a TM backup onto the new machine, as I wanted a 'clean' install. When I connect the existing TM drive to the new machine, it doesn't recognise that the machine is full of backups - is there a way around this?

TIA,

MJ.

A quick update on my own post...

I've realised that I need to name my new machine the same as the old one - now when I enter TM, I can see all of the backups there. But I can't create a new backup - TM syas that 80Gb are needed, and only 9Gb are available. This is true, but why is TM not automatically removing old backups as required?
