Run
md5sum F11_Home_Dave_20091217.tar.gz
on both machines. If you get two different results, something bad is happening.
I agree with the above! I take it one step beyond that. During my nightly backups, I have it create the hash for all my tarballs. Pretty simple to do. As an example:
if you have backup /home/you, /etc and /root to tarballs:
home.you.tar.gz etc.tar.gz root.tar.gz
Doing something like md5sum *.gz > checksum.md5 will create and store the hash info in the file, checksum.md5
Then to verify, md5sum -c checksum.md5 If all goes well, you'll see something like:
home.you.tar.gz OK etc.tar.gz OK root.tar.gz OK
Of course, you probably knew all this anyways.
