backup failed: invalid argument

Forgive me if I missed this searching the forum, but though I saw threads wrt i/o errors, this seems to be different.

It's been about 12 days since my last (of many) successful SmartUpdates and I decided to do an EraseCopy. This is an MBP, 10.6.4, and I've done several SmartUpdates and probably one or two EraseCopy's since the problem file was last updated.

IINM, it's a file in a VMWare Fusion package, and I'm pretty sure I have not run Fusion since way before my last few backups. Tried backup drive to both USB/FW (two different drives actually). I've retried the SD backup many times, after resetting the SMC, NVRAM, checked the source drive in Disk Utility, even booted as a target disk and tried it from another system.

A SmartUpdate targeting a drive that contains the last successful SmartUpdate does work, probably because that VMWare image hadnt been touched.

I have today run Fusion on that VM, then shut it down (from a Suspended guest to a Shut Down, so should have been sufficient to modify the file), but subsequent SD backup returned the same error.

Urusai! Happens about 3.5 hrs into the backup..

I'm not a software engineer but have done a bit of QA & I'm wondering 1) what could have changed wrt to this file that hasnt been touched in months, and 2) what's SD doing that returns an invalid argument in such a routine situation?

Here's the bottom of my SD log. Any insights greatly appreciated!

That usually means the destination drive failed during the copy... assuming you can duplicate the listed .vmdk in Finder (see the Troubleshooting section of the User's Guide)...

backup failed -- ok, bad computer

Thanks, Dave. I'd looked at the Troubleshooting section of the UG but I think it had just been too long a day staring at screens and I didnt pick up on the duplicate and replace technique. At that time I was not seeing any I/O errors, but subsequently I've seen plenty of them. Appears my MBP has a logic board problem causing power levels to usb & fw bus-powered drives to dive (usb drives wont mount and fw gets tons of i/o errors).

But I am curious, can you give any insight to the Invalid Argument error? What's happening specifically that causes SD's copy statement to have one? I was a bit mislead (not to say flummoxed .

-K

That's just Apple's translation of the error code it returns... the 'argument' is basically the drive itself as a destination of a disk operation.
