Yes, when you do a restore with pgbackrest, the recovery.conf will be set up to pull WAL from the repository to catch up. > - in pgbackrest streaming replication it can be only with "async state"? Note that pgbackrest doesn't use streaming replication for WAL as it's too slow, we use archive_command instead (and will run multiple parallel workers to get ahead of where archive_command is at, if there's WAL available to process and parallel workers are configured). It doesn't matter to pgbackrest if the replication between your primary and replica is synchronous or asycnhronous. Thanks! Stephen
