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.
You are advised to use the automated backup and manual backup functions of GaussDB to store backups to a professional storage object, such as the OBS, to ensure high data reliability and service assurance. Parent topic: Backup and Restoration
file list based on the archive slot (slot_name) and OBS directory address (src) entered by the user.

Object Storage Service (OBS) Stores automated and manual backups of your GaussDB instances. Cloud Eye Acts as an open monitoring platform that monitors GaussDB resources in real time.
Backup Flow Control Rate at which data is uploaded from the data disk of the instance to the backup storage device (such as OBS). The default rate is 75 MB/s. The value 0 indicates that the upload rate is not limited.
Value range: an integer ranging from 0 to 2147483647 Default value: 0 hadr_max_size_for_xlog_receiver Parameter description: Specifies the maximum difference between the OBS logs obtained by instances in the DR cluster and the local replay logs.
Backups are saved as packages in OBS buckets to ensure data confidentiality and durability. Since backing up data affects database read and write performance, you are advised to perform automated backups for tables during off-peak hours.
Value range: an integer ranging from 0 to 2147483647 Default value: 0 hadr_max_size_for_xlog_receiver Parameter description: Specifies the maximum difference between the OBS logs obtained by instances in the DR cluster and the local replay logs.
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.
Default value: 1 time_to_target_rpo Parameter description: In the remote DR mode of dual database instances, set the allowed time_to_target_rpo seconds from the time when an exception occurs on the primary database instance to the time when data is archived to the OBS recovery point
OM_Agent downloads archived logs from OBS to the corresponding node and creates a folder named with the first eight digits of the WAL file name. After the decoding is complete, the restored data is stored in a file and the file path is returned.
Billing Backups are saved as packages in OBS buckets. For the billing details, see How Is GaussDB Backup Data Charged? After a DB instance is deleted, the free backup space of the DB instance is automatically canceled. Manual backups are billed based on the space required.
The URL must be a shared object URL of OBS buckets. Constraints N/A Range N/A Default Value N/A sha_256 Yes String Definition SHA-256 string corresponding to the plug-in package.

If parallel restoration is enabled, all primary and standby replicas will simultaneously download backup data from the OBS server. Compared to serial restoration, this process demands a multiple of the bandwidth from OBS equal to the number of replicas in each shard.
