You can run full backup operation on both FSBased backup set and DumpBased backup set from the cluster client.
The backup operations are similar to traditional instances. For more information, see traditional backup.
Note
-
Set wal_log_hints to on in the configuration file or enable data checksums during cluster initialization. You must configure these settings during backup to perform restore to a particular time.
-
The DumpBased backup always run on the current master server instance, and the master server instance is identified during run time.
-
The FSBased backup runs on the first available standby server instance. The data backup phase identifies the standby server instance based on the priority order, and the log backup is performed depending on archive_mode value.
-
For streaming replication, if archive_mode is set to on, the log backup will be performed on the master node. If archive_mode is set to always, the log backup will be performed on the standby node by default.
-
For log shipping type, the log backup will be performed on the standby node by default.
-
If Always use master for log backup is selected, it will perform log backup from the master node irrespective of the value set for archive_mode.
-
It is recommended to set archive_mode to always to ensure backup of logs between the log only backup and failover.
