NAME¶

barman-cloud-backup - Backup a PostgreSQL instance and stores it in the Cloud

SYNOPSIS¶

barman-cloud-backup [OPTIONS] DESTINATION_URL SERVER_NAME

DESCRIPTION¶

This script can be used to perform a backup of a local PostgreSQL instance and ship the resulting tarball(s) to the Cloud. It requires read access to PGDATA and tablespaces (normally run as postgres user). Currently only AWS S3 is supported.

This script and Barman are administration tools for disaster recovery of PostgreSQL servers written in Python and maintained by 2ndQuadrant.

IMPORTANT: the Cloud upload process may fail if any file with a size greater than the configured --max-archive-size is present either in the data directory or in any tablespaces. However, PostgreSQL creates files with a maximum size of 1GB, and that size is always allowed, regardless of the max-archive-size parameter.

POSITIONAL ARGUMENTS¶

DESTINATION_URL: URL of the cloud destination, such as a bucket in AWS S3. For example: s3://BUCKET_NAME/path/to/folder (where BUCKET_NAME is the bucket you have created in AWS).
SERVER_NAME: the name of the server as configured in Barman.
