you can do it with shell access to your site.
upload that 140meg sql file to your site
log in to your site via a shell (ask your host about this if you don't know what it is since it may not be enabled)
run the command (replacing the loginname, databasename, backup.sql with they're respective names)
Code:
mysql -u loginname -p databasename < backup.sql
it should take a minute or 2 to run.
