Issues with Time Machine

Hi All,

I bought a Time Capsule in January 2010, and i've had backups since then.

Time Machine's interface has pretty much always been laggy as hell, but I've always put that down to using it over wifi, perhaps that was a wrong assumption.

Anyway, I went to open a folder in a virtual machine which resides in my mac's documents folder, and it wasn't there. Sure enough this folder wasn't in my documents folder, so I thought i'd restore it from time machine. Time machine shows every segment as a pink fully coloured one (signalling theres a backup there) for a few secs, before most of them turn into a pale pink. Looking into the issue further, it seems as though I don't have permission to access the documents folder on a lot of backups, by looking at the users/brett/ folders on them (which i do have access to).

I have gone through two MBPs with the same backup set, and a number of hard drives (the latest being a SSD I put in yesterday, and the migration assistant restore from time machine worked without skipping a beat - never had a problem doing full restores or migrations, just using the interface)

Obviously the easiest thing to do would be to start afresh, but I'd rather not as I'd lose 2 years worth of backups, and who's to say this wouldn't just happen again in the future? Could this be why the interface is so slow too?

Thanks guys
