Some simple suggestions in addition to the one about experimenting
with block size:
* Does the output of mysqldump compress well with gzip?
If so, you could try compressing it with a version of gzip that
supports the --rsyncable option. The version in Debian or Ubuntu
Linux supports this option.
* If you're confident that you have a good line-oriented dump, how
does diff cope when comparing 2 dumps?
rsync and diff obviously use very different schemes for figuring out
what is different. However, sometimes doing a diff will show you
something obvious that you have missed. Obviously you'll need 68GB
of free disk to be able to try that!
* If you're not telling rsync to transfer just a single file, do the
filenames match at both ends of the transfer?
You not doing something like creating a dump with the date in the
filename, are you?
Sorry, no rocket science there... ;-)
peace & happiness,
martin
