Hi Craig,

After I did the changes below and restared BackupPC a full backup succeeded. 
This I found odd so I reverted back to the original Attrib.pm file and queue'ed 
another full backup - this succeeded. I suspect the problem in the first place 
after the upgrade to 3.2.0 was backupPC didn't restart properly (probably due 
to this being a custom install on Solaris and a home grown init.d script). 
Consider this request closed.

Thanks again for a great product and the speedy replies,
