I love the way Time Machine works. And I'm smart enough to have excluded certain folders, like Music and others.
But I foolishly forgot to exclude my virtual machines.
That's 3GB+ that's now been backed up, and Time Machine sees the disk image as one files, so minor changes have also been stored (at a cost of 3GB!).
I only found out when I ran out of space and I ran GrandPerspective
Central and found four big stinkers in there.
I've excluded those folders now... so... I guess... with subsequent updates these big files will come out in the wash. But I'd really like to free up the space (just in case).
Is it possible to delete the files? Time Machine says 'no'.
Do any super users know any different?
