Note
- Due to the architecture optimization of the physical backup and restore feature in OceanBase Database V4.x, this parameter has been deprecated since OceanBase Database V4.0.0.
- OceanBase Database V4.x implements the features corresponding to this parameter in the following ways:
- You can use the tenant-level parameter archive_lag_target to specify the lag of log archiving.
- You can use the
RECOVERY_WINDOWparameter in the ALTER SYSTEM ADD DELETE BACKUP POLICY statement to specify the time window for restoring backup data in thesystenant or a user tenant. - Expired backups can only be automatically cleaned up and cannot be manually cleaned up. For more information about the automatic cleanup, see Automatically clean up expired backup data.
- You can use the ALTER SYSTEM SET LOG_ARCHIVE_DEST statement to specify the interval for generating a new log piece.
- Second backup (or backup of the backup) is no longer supported. Therefore, you cannot specify the number of copies of a backup set.
backup_dest_option specifies the parameters for backup.
