assuming it's MySQL that you're talking about, all you need to do is use the console-based "mysqldump" application to grab the dump, and "mysql" to install the dump.
mysqldump -uusername -ppassword dbname -hhostname > dump.sql
mysql -uusername -ppassword dbname -hhostname < dump.sql
if you find there are timeout issues, then upload the file to the server, and either run the "mysql" line above yourself, or ask your ISP to run it, if you don't have ssh access. |
