AWS_ACCESS_KEY_ID - AWS access key ID.
AWS_SECRET_ACCESS_KEY - AWS secret access key, sometimes also called an application key.
AWS_S3_BUCKET - The name of the bucket that the access key ID and secret access key are authorized to access.
AWS_S3_REGION - The name of the region your bucket is located in, set to auto if unknown.
BACKUP_DATABASE_URL - The connection string of the database to backup.
BACKUP_CRON_SCHEDULE - The cron schedule to run the backup on. Example: 0 5 * * *
AWS_S3_ENDPOINT - The S3 custom endpoint you want to use. Applicable for 3-rd party S3 services such as Cloudflare R2 or Backblaze R2.
AWS_S3_FORCE_PATH_STYLE - Use path style for the endpoint instead of the default subdomain style, useful for MinIO. Default false
RUN_ON_STARTUP - Run a backup on startup of this application then proceed with making backups on the set schedule.
BACKUP_FILE_PREFIX - Add a prefix to the file name.
BUCKET_SUBFOLDER - Define a subfolder to place the backup files in.
SINGLE_SHOT_MODE - Run a single backup on start and exit when completed. Useful with the platform's native CRON schedular.
SUPPORT_OBJECT_LOCK - Enables support for buckets with object lock by providing an MD5 hash with the backup file.
BACKUP_OPTIONS - Add any valid pg_dump option, supported pg_dump options can be found here. Example: --exclude-table=pattern
NODE_VERSION - Specify a custom Node.js version to override the default version set in the Dockerfile.

If backing up a Postgres 17 database imported from Postgres 16, set PG_VERSION=17 and NODE_VERSION=22.
