How can I Backup and Restore a MySQL database?
METHOD 1 – PHPMyAdmin
You can use PHPMyAdmin to backup/restore your database if it is relatively small (~10MBs)
If your database is larger than that please skip to METHOD 2 – command line
BACKUP:
- Select the database you’d like to back up from the column on the left
- Click on “Export” from the top set of tabs
- Select the tables from the list that you would like to backup. If you want to backup the entire database hit “Select All“
- Select “Structure and data” from the bullet list
- Selection boxes:
- Check the “Add ‘drop table‘” box if you are moving the database to a new location and don’t want to merge the old table with an existing one
- Click the “Save as file” box
- Use the “Save as file zipped” if you want to compress the backup before downloading it from the server
- Click the “Go” button, when prompted save the file to your local computer
RESTORE:
- From the column on the left select the database that you want to restore to. If one doesn’t exist you must first create it.
- Click on “Import” from the top set of tabs
- Click on the “Browse” button next to “Or Location of the textfile:” near the bottom
- Browse to the local backup and click “Open” ( If you have the local backup in a non-text file format, e.g. you selected “Save as file: zipped” when you backed up the database, you’ll have to unzip the file on your local computer before you can select it during this step )
- Click the “Go” button ( You should get a message like this:
Your SQL-query has been executed successfully :
The content of your file has been inserted. (X Instructions) )
METHOD 2 – command line
This method works regardless of the size of your database. You must have SSH access to your server.
BACKUP:
- Log into your server via SSH and cd into a directory where your user has write access
- Enter the following command:
mysqldump –add-drop-table -u Username -p dbname > dbname.sql- omit the ‘–add-drop-table‘ argument if you’ll want to merge this backup with an existing database upon restore
- username is replaced by the MySQL username
- Replace dbname with the name of the database to be backed up.
- Replace dbname.sql with what you’d like to name the backup.
- Enter your MySQL password at the prompt.
- If you get an error that looks like this:
ERROR 1045: Access denied for user: ‘Username@localhost’ (Using password: YES)
you have entered an incorrect password. Please retype it carefully, or reset your password via the WebControl Panel or Plesk Control Panel
- If you get an error that looks like this:
- Use FTP to download the file to your backup location, probably your local computer.
- Don’t forget to delete the backup from your public html directory after you’ve found a safe place for it. You don’t want to leave your backup lying around where anyone with a web browser can download a copy.
RESTORE:
- Use FTP to upload the file to your server, your public html directory will work for now
- Don’t forget to delete the backup from your public html directory after you’ve done the database restoral. You don’t want to leave your backup lying around where anyone with a web browser can download a copy.
- Log into your server via SSH and cd to the directory where you’ve uploaded the file.
- Enter the following command:
mysql -u Username -p dbname < dbname.sql
- username is replaced by the MySQL username.
- Replace dbname with the name of the database to be restored.
- Replace dbname.sql with the name of the backup.
If you have a zipped backup of your database you can use this line instead:
gunzip < dbname.gz | mysql -u username -p dbname
- Where username is replaced by the MySQL username.
- Replace dbname with the name of the database to be restored.
- Replace dbname.gz with the name of the backup.
- Enter your MySQL password at the prompt. If you don’t know it you can reset it in your webcontrol or Plesk admin panel
- If you get an error that looks like this:
ERROR 1045: Access denied for user: ‘Username@localhost’ (Using password: YES)
you have entered an incorrect password. Please retype it carefully, or reset your password via the WebControl Panel or Plesk Control Panel.
- If you get an error that looks like this:
