Hi guys. I may just not be understanding how these things work, but even my IT-educated friend says this seems dumb. You can see the error in the pic below.
Trying to back up, says it needs 636 GB but only 464 GB are available... this doesn't make sense to me as my internal HD is only 750GB and has 209GB free. The external is 1TB I'm pretty sure (I don't have it with me right now.)
The external HD long ago ran out of enough space to keep more than a few dates' worth of Time Machine backlog, and now there is only one. Which I don't really mind, as I've never really had need for the actual going-back-in-time function, though I know it might come in handy so I will be getting a new external at some point.
But, is this a legit thing? Does it really need that many GB of "working" space? Is there any way I can make it back up right now?
other relevant info: I'm running 10.7.5 on my 20111 Macbook Pro.
My internal HD is on its way out (iTunes refuses to open and other stuff is slowly borking up) so I know I need to buy a new one of those ASAP too.
Thanks guys!
