I backup two computers to the same archive, backing up user files every day and backing up the full drives weekly to pick up system changes, etc. This system runs smoothly so I don't pay much attention to it most of the time. I've just noticed that for the past couple of months the log has been showing "Capture issues" for the full disk backups from both computers. The user files backups on both commuters seem to be fine. I just noticed the problem after installing the latest beta, but it was apparently going on for a while before that.

On my MacBook Pro the problem seems to be the same every time, as follows:

On he iMac, the problem sometimes identifies as "folder dev" with nothing deeper showing, like this,

How much should I worry about this? Is it just telling me that a few particular files didn't get captured, or is there some more problematical going on here?

There's a problem/bug in Lion wherein an attempt to access the /dev directory on the startup volume using the core filesystem APIs results in an I/O error.

It doesn't happen on all systems, and it doesn't happen all the time. For months I was unable to reproduce this problem, and then last week my primary development system started showing the same symptoms. I've filed a bug report with Apple a few days ago. It's such a bizarre and blatant error that I'd be surprised if they're not already aware of the problem, but I don't know what's being done about it.

I'm 80% sure that this is an innocuous problem, but I need to do more testing to be sure. Normally, there's nothing in the /dev directory for QRecall to capture, since it's populated almost exclusively with logical device files. So not capturing it shouldn't make any difference.

OK, thanks. I'll ignore the Capture issues, or perhaps just exclude /dev from the backup.
