Howdo you total the file size field from tar tvf output to verify the backup size is the same as the restored size?
Thanks.

Something like this should work:
Code: 
tar tvf foo.tar | awk '{sum+=$3}END{print sum}'
This is assuming your version of tar prints the size value in the 3rd column of your output...
Hope this helps :)
