Parallels 6 - Windows 7 PVM file cannot be backed up

[goldretrvr]

I posted something about this on the Parallels Forum site, but have not gotten any response this past week from Parallels support.. so I thought I would share here as well..

When I backup my Mac (using SuperDuper), the backup fails on the Windows 7.PVM file. I tried simply duplicating the file (using Duplicate in Finder), and it fails.

I get the following error:
"The Finder can't complete the operation because some data in "Windows 7 (Office 2010).pvm can't be read or written. (Error code -36)"

The VM file is about 20gb
I'm running SL 10.6.8
MacBook Pro 4,1 2.6ghz / 4gb ram
Parallels Desktop 6 for Mac, build 6.0.12094

I have tried the following:
- duplicate VM file from Finder (fails about 8-9gb in)
- run CHKDSK from the Windows VM
- Repair Permissions in Disk Utility (Mac)
- Repair Disk in Disk Utility (Mac)
- clone VM (within Parallels)
- booted from a different drive and tried using Duplicate from Finder menu

I am stumped - does anyone have any suggestions on how to determine why my Win7 VM will not backup / copy??

The VM boots fine, and everything seems to work fine once booted up into the Win7 environment.

Thanks for any assistance you can provide.
