[Novalug] rdiff-backup runtimes?

I've had power handling problems with Ali based USB cards in the past.
They, indeed, are very flaky.

Well, it seems that the chipset on the controller card
I plugged this drive into was flaky. It was an Ali USB
chipset. I plugged the USB drive into a different card
with an NEC chipset and I haven't seen a single USB
reset message in the system log. 

Note to self: NEVER buy USB cards with anything other
than NEC chipset!

Thanks again,
  Brandon
