My Time Machine backups on Time Capsule have been pretty good in the last few months. In the last week or so I am seeing painfully slow backups. It's not the preparing or the finishing phase, it's the backup itself. Data transfer for other apps is fine. The backup transfers about 50 Kb per second. In more than 3 hours it backed up about 600 Mb. Here's what I get from the Console:

Any clue? What happened? (I did an Airport-related upgrade recently)

My set up is a Time Capsule and an Airport Extreme.
