Backups cannot be automated within Tungsten Cluster, instead a cron job should be used to automate the backup process. cluster_backup is packaged with Tungsten Cluster to provide a convenient interface with cron. The cron entry should be added to every datasource or active witness in the cluster. The command includes logic to ensure that it will only take one backup per cluster by only running on the current coordinator. See Section 8.8, “The cluster_backup Command” for more information.
/opt/continuent/tungsten/cluster-home/bin/cluster_backup -v >> » /opt/continuent/service_logs/cluster_backup.log
The command output will be appended to
for later review. Use your preferred mechanism to configure
cron to execute this command on the desired schedule.
An example cron entry:
crontab -l00 00 * * * /opt/continuent/tungsten/cluster-home/bin/cluster_backup >> /opt/continuent/service_logs/cluster_backup.log 2>&1
All output will be appended to
echo "datasource host2 backup" | /opt/continuent/tungsten/tungsten-manager/bin/cctrl -expert
