Time machine is very slow

I'm using TM to back up a 150 Gb drive to a 591 Gb partition (Mac OS Extended (Journaled)) on a 1 Tb Lacie D2 Quadro connected via Firewire 800.

A TM backup usually takes more than 1 hour. Due to this, I decreased frequency to every 6 hours, but even so, during the 1+ hours the backup takes, the machine is only marginally usable.

Below is an excerpt from my system.log file bracketing a TM backup.

In contrast, I occasionally use Silverkeeper (a free backup tool provided by Lacie) to create a bootable backup to another partition on the same drive. Even though I only do this every week or so, the Silverkeeper backup only takes about 3/4 hour.

I've now had CCC running for a few days -- no problems.

More confirmation that something is wrong in some part of your OS that TM (and, perhaps, Silverkeeper) uses, but CCC doesn't, maybe the File System Event log (or something related to it).

Rather weak confirmation, I'd say; weaker than if CCC failed as well, for example.

Glad you've got something working, but I sure would like to know what's actually wrong (I suspect Apple would, too -- hint, hint!)

Well, ummm, how would I bring it to Apple's attention, if I wanted to?

If you still have Apple Care, of course, contact them.

Near an Apple store? Make an appointment at the Genius Bar.

You can try feedback at: http://www.apple.com/feedback/macosx.html. They'll take a look, especially to well-documented problems, but they don't normally respond individually.

Try Talk To Us / Contact Support on the left side of Apple's main support page at: http://www.apple.com/support/
You can schedule a callback. I think there is a charge for this, hopefully nominal.
