Time machine error

[Sir Loin Steak]

Any one have a clue what this means? Does it mean my external drive is full?

Have you changed anything in your Mac? New motherboard? Upgraded to SL?

 

[Sir Loin Steak]

No, nothing's changed.

Appears to be plenty of space left in the volume.

Try going into Disk Utility and checking what format the disk is. Also try to repair the disk from there.

Thanks both. I've carried out the instructoins on site, and the result is this:

Hmphh. Maybe it's ok now:

I have seen this happen every 2-3 days on my machine. I believe it happens when switching around users - specially to my son's account, which doesn't have any permissions. It might be that his account doesn't have permission to copy/write files from the hard drive or to the backup drive, and then throws this error.

Whenever I've had it, I generally do a TM update manually (thru the menu bar, select "backup now"), and it has succeeded.

I have not been overly worried, since the subsequent backup has completed successfully.

We don't switch users much, only if I'm experimenting, and I can't link the two events, but yes, it's possible that it was caused by this switching.
