You can use mysqldump.exe to dump just the tables you want, or I found a great tool for managing mysql:
DBTools I would subbest that you just write a query to copy the info you want to/from another backup database.
Edit: Use this command line command to backup your account and character data (run from the mysql\bin directory)
Code:
mysqldump.exe -t eq23 account character_ > backup.sql
where:
eq23 = database name
account = 1st table to output
character_ = 2nd table to output
backup.sql = output file for data
Add more tables if you want.
then use:
Code:
mysql.exe -f eq23 < backup.sql
to restore the data
