Renaming a database during a restore

NetVault Backup lets you select a backed-up MySQL database and rename it for a restore so that it does not overwrite the existing version of that database. This process can be useful when creating a copy of an existing database. To accomplish this process, perform the steps outlined in the following topics.

* 
IMPORTANT: Only complete databases can be renamed for a restore. Attempts to rename an individual table are met with an error message.

Before conducting a restore rename, review this list of known limitations and intended uses for this operation:

•
Valid restore sequences are limited to Full or Individual Database/Table Copy Only backups.
•
Not allowed during Incremental and Differential Restores.
•
Can be used with a restore to a different MySQL Instance or MySQL Server.
1
In the Navigation pane, click Create Restore Job, select Plug‑in for MySQL from the Plugin Type list, select the applicable saveset, and click Next.
For more information, see Selecting data for a restore.
2
On the Create Selection Set page, select the database that you want to rename.
3
From the Actions list, select Rename.
4
In the Rename/Relocate dialog box, enter the new name in the Rename to box, and click Ok.
The database item is accompanied by renaming information in parentheses.
5
Continue with the restore as explained in Restoring data in MySQL.

Restoring to a different MySQL Instance on the same server

In this form of relocation restore, a Plug‑in for MySQL backup is to be restored to the same MySQL Server machine, but to a different instance of MySQL that has been configured there.

Figure 1. Data backed up on one MySQL Instance and recovered to different instance

To accomplish this process, perform the steps outlined in the following topics.

Known limitations and intended uses

Before conducting a relocation restore, review this list of known limitations and intended uses for this operation:

•
Valid restore sequences can include Full, Incremental, Differential, and Individual Database/Table Copy Only backups.
•
Only restored Binary Logs from an Incremental or Differential Backup can be applied to the destination instance; that is, current Binary Logs from the source instance cannot be applied to the destination instance.

Prerequisites

The following prerequisites must be met before a restore of this type can be set up and run.

•
Existing and target machines must have the same Installation configurations: Both machines must have the following established, regarding MySQL:
•
Same OS installed
•
Same version of MySQL installed
•
Same installation and base directory
•
Same MySQL “Data” directory
•
New target instance must be successfully configured in Plug‑in for MySQL: The process outlined in Configuring the plug-in must have been successfully performed to add the new MySQL Instance; that is, the target instance must be revealed and accessible within the Plug‑in for MySQL node on the NetVault Backup Selections page.

Setting up and starting the restore

With the prerequisites met, perform the following steps to set up this form of relocation restore job.

1
In the Navigation pane, click Create Restore Job.
2
On the Create Restore Job — Choose Saveset page, select Plug‑in for MySQL from the Plugin Type list.
3
To filter the items displayed in the saveset table further, use the Client, Date, and Job ID lists.
The table displays the saveset name (job title and saveset ID), creation date and time, and size. By default, the list is sorted alphabetically by saveset name.
4
In the saveset table, select the applicable item.
When you select a saveset, the following details are displayed in the Saveset Information area: Job ID, job title, server name, client name, plug-in name, saveset date and time, retirement setting, Incremental Backup or not, Archive or not, saveset size, and snapshot-based backup or not.
5
Click Next.
6
On the Create Selection Set page, select the data that you want to restore.
Display the individual MySQL Instance that was the target of the backup, navigate the selection tree until the applicable data items are located, and select them for inclusion.
7
With the applicable databases selected, click Edit Plugin Options, and then click the Restore Destination tab.
8
In the Restore Destination Details section, enter the following:
•
Username: Enter the login account name used to access the target MySQL Instance.
•
Password: Enter the password associated with the login account.
•
Instance Name: Enter the NetVault Backup name established for the new instance of MySQL, based on what was established during its configuration in NetVault Backup — this name is the name established as the MySQL Instance Name in the Configure dialog box ; for more information, see Configuring the plug-in.
9
If applicable, select the applicable options on the Point-in-Time Recovery tab.
These options are not required to perform this form of restore. For more information, see Setting restore options.
10
To save the settings, click Ok, and then click Next.
11
In Job Name, specify a name for the job if you do not want to use the default setting.
Assign a descriptive name that lets you easily identify the job when monitoring its progress. The job name can contain alphanumeric and nonalphanumeric characters, but it cannot contain non-Latin characters. On Linux, the name can have a maximum of 200 characters. On Windows, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
* 
IMPORTANT: Do not use special characters that are not supported in a filename on the target OS. For example, the characters /,\,*, and @ should not be used on Windows. This requirement is because Plug‑in for MySQL tries to create a folder with the same name as the job title for restoring data temporarily.
12
In the Target Client list, select the machine on which you want to restore the data.
* 
TIP: You can also click Choose, and then locate and select the applicable client in the Choose the Target Client dialog box.
13
Use the Schedule, Source Options, and Advanced Options lists to configure any additional required options.
14
Click Save or Save & Submit, whichever is applicable.
You can monitor progress on the Job Status page and view the logs on the View Logs page. For more information, see the Quest NetVault Backup Administrator’s Guide.
