Scheduled backup

KubeBlocks supports configuring scheduled backups for clusters.

kbcli cluster update mysql-cluster --backup-enabled=true \
--backup-method=xtrabackup --backup-repo-name=my-repo \
--backup-retention-period=7d --backup-cron-expression="0 18 * * *"
  • --backup-enabled indicates whether to enable scheduled backups.
  • --backup-method specifies the backup method. You can use the kbcli cluster describe-backup-policy mysql-cluster command to view the supported backup methods.
  • --backup-repo-name specifies the name of the backupRepo.
  • --backup-retention-period specifies the retention period for backups, which is 7 days in the example.
  • --backup-cron-expression specifies the backup schedule using a cron expression in UTC timezone. Refer to cron for the expression format.

You can also execute the following command to view cluster information, where the Data Protection: section displays the configuration details of automatic backups.

kbcli cluster describe mysql-cluster
