Value range: Boolean on indicates that the query covering the OBS is accelerated based on the cost when the computing resource pool is available. off indicates that no query is accelerated using the computing resource pool.
Default value: 1 time_to_target_rpo Parameter description: Specifies the maximum time_to_target_rpo seconds from the time when an exception occurs on the primary cluster to the time when data is archived to the OBS recovery point in dual-cluster remote DR mode.
Backups are saved as packages in OBS buckets to ensure data confidentiality and durability. Since backing up data affects the database read and write performance, you are advised to perform automated backups for tables during off-peak hours.

It takes some time to back up and upload incremental log files (The time depends on the network and OBS traffic control). Note that the backup completion time does not represent the data consistency point that can be specified when this backup set is used to restore data.
