What's your backup device ? If it's a SCSI tape then I'd say your problem is 
most likely SCSI cabling termination. I had this a long time ago and it drove 
me nuts. I eventually found that the SCSI chain wasn't terminated correctly. 
Just like you, I would only encounter the problems on big backups (because it 
was only producing occasional errors, and the bigger the file, the more 
likely I was to encounter it. The way to fix the problem is to make sure that 
all SCSI cable connections are well made and that termination is correct. 
Using good quality SCSI cables is a big help too.

If OTOH you're not using SCSI tape then I'm afraid I'm all out of clue.
