How to copy Mysql database from one Computer to another / backup database using mysqldump

  1. We can transfer a MySQL database from one PC to another PC using mysqldump command.

  2. We have to create dump file of database to transfer database from one PC to another PC.

  3. MySQL database is not portable database i.e. we cannot transfer it from one PC to another PC by copying and pasting it.

  4. We can use following method to transfer database.

  5. Creating a dumpfile from database/ Taking backup of MySQL database:

  6. Open command prompt.

  7. Execute following commands to change directory

>c:  “press enter”

For a database named "lbry", try this:

mysqldump -u root -p lbry > dump-lbry.sql

Create a database of the same name ("lbry" in this example) on the computer to which you wish to copy the database contents

Then import it:

mysql -u root -p lbry < dump-lbry.sql

The only SAFE way to copy databases from one machine to another is to first quiesce the database (make sure no clients are modifying it), then use the mysqldump command to create a text representation of your schema and the contents of your tables. Then copy that text file over to the other machine and read it in by specifying it as the input to the mysql command.

Attempting to copy the actual mysql data directories over is asking for trouble, since they are dependent on the architecture of the machine that mysql is running on and likely on the version of mysql and whatever storage engine is in use.


You can do by this process step-by-step using MySQL WorkBench.

  1. Install MySQL Workbench
  2. Connect to existing Database
  3. Go to Navigator -> Management -> Data Export. (this will dump queries of tables one by one in a separate folder, Workbench uses the same folder to import)
  4. Create Database on target PC.
  5. Connect to Target Database (would consist of 0 tables in DB)
  6. Go to Navigator -> Management -> Data Import/Restore. (this will use the dump folder and create tables in your target Database).

Hope this helps.
