7.8. Backing Up and Restoring Configuration With Cluster Manager CLI

The Cluster Manager CLI provides scripts that you can use to backup and restore your configuration: cdbDump and cdbRestore. These scripts are installed in the /var/cluster/cmgr-scripts directory. You can modify these scripts to suit your needs.

The cdbDump script, as provided, creates compressed tar files of the /var/cluster/cdb/cdb.db# directory and the /var/cluster/cdb.db file.

The cdbRestore script, as provided, restores the compressed tar files of the /var/cluster/cdb/cdb.db# directory and the /var/cluster/cdb.db file.

When you use the cdbDump and cdbRestore scripts, you should follow the following procedures:

• Run the cdbDump and cdbRestore scripts only when no administrative commands are running. This could result in an inconsistent backup.

• You must backup the configuration of each node in the cluster separately. The configuration information is different for each node, and all node-specific information is stored locally only.

• Run the backup procedure whenever you change your configuration.

• The backups of all nodes in the pool taken at the same time should be restored together.

• Cluster and Linux FailSafe process should not be running when you restore your configuration.

  Note: In addition to the above restrictions, you should not perform a cdbDump while information is changing in the CDB. Check SYSLOG for information to help determine when CDB activity is occurring. As a rule of thumb, you should be able to perform a cdbDump if at least 15 minutes have passed since the last node joined the cluster or the last administration command was run.
