Restoring a MySQL Database

h2. Restoring a MySQL Database

You can restore a MySQL database by following the instructions below in your CDP 3.0 Enterprise or Advanced Edition.

1. Log in to the Web Interface of the backup server containing the backups for the MySQL Database you want to restore. (See [Accessing Enterprise Edition Web Interface], [CDP3:Accessing Advanced Edition Web Interface].)

3. In the "Recovery Points" list, select a Recovery Point containing the necessary database replication.
{info:title=Tip}To find a Recovery Point, you can use the Basic and Advanced List Filters. See [Customizing the Recovery Points List|http://wiki.r1soft.com/display/CDP3/Customizing+the+Recovery+Points+List].

7. In the appeared "Restore Databases" wizard window, define the options for the restore.

On the first screen, familiarize yourself with the introductory information and click "Next" to proceed.

8. On the "Host" screen, you have two options for selecting the host to restore to:
* *Restore to Original Host* - If you select this option, the restore will be done to the Agent where the source database was located. If the database exists, it can be overwritten.
* *Restore to Alternate Agent* - Select a destination Agent which is already added to the system. Specify the Database host and port.

In our example, we selected the "Restore to Original Host" option. For information about restore to alternate Agent, refer to [CDP3:Restoring MySQL Databases to Alternate Locations].

Select an option and click "Next" to proceed to the following step.

9. On the "Authentication" screen, you have two options to specify to connect to the database.
* *Use Original Authentication Credentials* - Connects using the default username and password used to backup the database instance.
* *Specify Alternate Authentication Credentials* - Allows you to set username and password different from the default. The user must have full administrator-level access to the database instance you are going to restore.

Select an option and click "Next" to proceed to the following step.

10. The next "Temporary Instance" screen.

When restoring tables, the system needs to create a temporary directory on the target agent for the restore. There are two options for this:
* *Use Default Temp Directory* - Creates a directory in an OS-specific default location ({color:blue}C:\Temp{color} for Windows, {color:blue}/tmp{color} for Linux).
* *Specify an Alternate Temp Directory* - Allows you to control exactly where the temp directory is created on the agent.

This screen also allows you to specify the Virtuozzo Container ID (optional) and input the Connection Information.

Select an option and click "Next" to proceed to the following step.

11. The following screen is "Data Directory." By default, database configuration retrieved during discovery is used. In some environments, this path does not point to the actual location on the filesystem for the data. To remedy this, you can choose to specify the exact path for the data directory. This will ensure that we can locate the data files for the database during the restore.

Select an option and click "Next" to proceed to the following step.

12. The next screen is "Base Directory." By default, the system automatically determines where on the filesystem the necessary program files are located. In some environments, the automatic method fails. To remedy this, you can specify the exact path for the base directory.

Select an option and click "Next" to proceed to the following step.
