I didn't include this since the OP specified _other_ than tar, 
replication and mysqldump.

But the most efficient and lowest downtime is to combine replication 
with the LVM snapshot and rsync. Since the OP specified he has around 
100 GB of data, rsyncing the snapshotted data directory will be 
substantially more efficient than using mysqldump for transfer to the 
remote system (assuming he doesn't churn most of the contents of the 
database between syncs).
