Hi ,

Help is needed* to restore mysql data

This is the the setup.

2 Servers running on CentOS.

one server has both apache an mysql.

the other server only has mysql database. This server has about 12000 records in the database. Last week, It had* about 6000 records. then, Someone has* backed up these 6000 records to the web server. Now , We need to backup all 12000 records to the webserver.


How to archive this task?

If I restore these 12000 records to the web server, it already has 6000 records. Then, whall will happen? Shoud I override them?

Remember, this is a PRODUCTION SERVER.. I should do it properly.



I think I will have to do following steps.

first, I will have to dump the mysql server backup from database server.

This is the command I will have to enter from the database server.




mysqldump -u root -p databasename >
database.txt


then, I will have to mount a flash drive and copy database.txt to the flash drive.

Then, I will have to go to the web server and mount it there.

Then, finnaly, I have to restore
database.txt to web server as follows.


mysql -u root -p databasename < databas.txt


Am I RIGHT?

This data is extremely essential. I should be able to do it properly.

Any IDEAS?

You might want to add --add-drop-table to your mysqldump

Most production data is extremely essential

You might also want to use -Qc, so that you quote the data and do
complete inserts. This depends mostly on the version of mysql that
you're running, which I didn't see in your initial post. Better safe
than sorry.
