 ### Backup File Name / Path
 By default, if `POSTGRES_BACKUP_ALL` is true, the dump file will be put at `<S3_PREFIX=''>/all_<timestamp>.sql.gz`. When using `POSTGRES_DATABASE`, each database listed will be backed up to the object path `<S3_PREFIX=''>/<database>_<timestamp>.sql.gz`.
 
-If you wish to make these filenames static, you can use the `S3_FILE_NAME` variable, which will change these formats to `<S3_PREFIX>/<S3_FILE_NAME>.sql.gz` or `<S3_PREFIX>/<S3_FILE_NAME>_<database>.sql.gz` accordingly.
