barman-cloud-restore [OPTIONS] SOURCE_URL SERVER_NAME BACKUP_ID RECOVERY_DIR

This script can be used to download a backup previously made with barman-cloud-backup command. Currently AWS S3, Azure Blob Storage and Google Cloud Storage are supported.

This script can also be used to prepare for recovery from a snapshot backup by checking the attached disks were cloned from the correct snapshots and downloading the backup label from object storage.

This script and Barman are administration tools for disaster recovery of PostgreSQL servers written in Python and maintained by EnterpriseDB.
