đī¸ High availability
ob-operator ensures the high availability of data by using the following features of OceanBase Database.
đī¸ Recover from node failure
This topic describes how to recover from the failures of OBServer nodes by using ob-operator.
đī¸ Back up a tenant
This topic describes how to back up the data of a tenant. OBTenantBackupPolicy and OBTenantBackup resources are key to tenant data backup. You can use OBTenantBackupPolicy to define backup policies and OBTenantBackup to define backup jobs. A backup policy specifies the interval of log archiving and data backup parameters for a tenant in an OceanBase cluster. When a backup policy takes effect, a backup job is created to execute specific operations. The backup destination can be a Network File System (NFS) volume or an Alibaba Cloud Object Storage Service (OSS) bucket.
