file size differences

[Sean Roe]

Hi All,

I am having trouble figuring out a problem and I was hoping another view 
point on it might help:

1) I make a mysql dump every night on one of our database servers.  It 
ends up getting tarred and gzipped
2) In the morning I unzip the sql file and run a  sum on it, example:
#sum nightly.sql
47339 3641964
3) I ftp the sql file over to another machine I have tried this in both 
ascii and binary mode.
4) I sum the file on the second machine:
forumsdb:~# sum nightly.sql
00520 3641964

as you can see the sums are different.  I am at a loss as to why. 
Anyplace I should look?
BTW Box 1 is a debian Sarge box running 2.6.8-11-amd64-k8-smp kernel
and Box 2 is Fedora Core 5  box running 2.6.15-1.2054_FC5 kernel

Thanks,
Sean
