Restoring data

Restoring data to a Virtual Client is conducted in the same manner as a restore performed to a traditional NetVault Backup Client. All options available for a restore with Plug‑in for MySQL are also available for Failover Clustering environments, and data selection is performed in the same way as well. The only difference is that restorable backups of a Virtual Client are displayed on the Create Restore Job - Choose Saveset page under the name of the Virtual Client, not the specific NetVault Backup Client or node that was active during each backup. When a restore job is initiated, NetVault Backup will communicate with all member Clients to determine which machine is currently in control of the failover cluster, and then target this machine for the restore.
All the instructions offered in reference to performing a restore can be used in the recovery of a Virtual Client. For more information on restoring a NetVault Backup Virtual Client, see the various sections in Restoring Data. To restore a NetVault Backup Virtual Client to a standalone NetVault Backup Client, use the instructions provided in Recovering to an Alternate MySQL Server.


NetVault Backup 10.x uses a PostgreSQL database. If the PostgreSQL database does not start, NetVault Backup cannot start. To correct this issue, delete the “” file from the location referenced in the log and restart the NetVault Backup Server. For more information, refer to
Access the Manage Devices page of the NetVault Backup WebUI, and perform a scan of the media targeted by the job. NetVault Backup stores index information for backup jobs in two locations: in the NetVault Database and on the media targeted by the backup. Performing this scan adds the index information to the NetVault Database. To verify this, open the Create Restore Job - Choose Saveset page and locate the specific job. If you can browse it and set up a restore job, the scan process has corrected the problem.
If a backup fails with a message similar to “Failed to start Replication slave server,” it might indicate that you selected the Enable MySQL Replication check box but did not configure replication. To correct this issue, either clear the Enable MySQL Replication check box on the Configure dialog or set up replication, and then execute the backup job again. For more information on updating the configuration, see Configuring the plug-in; for more information on replication, see Working with native MySQL replication.
