Backup server extremely slow

[Guest Toasterman]

We use BackupPC at work on an Ubuntu server. It has gotten extremely slow during the past 2 weeks and I haven't been able to figure out why. It always worked perfectly before. It takes about 10-15 minutes to start back up after shutdown. Any commands issued via SSH are also extremely delayed.

 

There is more than enough RAM and the CPU is barely touched. Here's my out put of top:
