Dumping To a Remote Host

When running a mysql dump to a remote host directly over ssh the host database will be locked until the sync has finished. (Can be up to 5-10 minutes for lager databases)

The above problem can be easily circumvented by dumping to a file and than cating the file into ssh to the remote host as such. 

mysqldump --verbose -u<localDbUser> -p<localDbPassord> <localDbName> > /tmp/<dbName>.sql && cat /tmp/<dbname>.sql | ssh user@remote.host mysql -u<remoteDbUser> -p'<remoteDbPassword>' <remoteDbName>

Note: The above should work without issue but has not undergone much testing yet.
