Как задать количество хранимых бекапов гем backup?

Question

[Антон Мисягин]

Для бэкапа базы данных использую гем backup, что на ruby
Не получается задать количество последних бекапов. Количество растет с каждым днем
backup.rb

require 'yaml'
db_config = YAML.load_file('/var/www/site/shared/config/database.yml')['production']
smtp_config = YAML.load_file('/var/www/site/shared/config/backup_smtp.yml')

Model.new(:backup, 'Backup [production]') do
	
	compress_with Gzip do |compression|
		compression.level = 6
	end

	encrypt_with OpenSSL do |encryption|
		encryption.password = 'simple-password'
		encryption.base64   = true
		encryption.salt     = true
	end

	database PostgreSQL, db_config['database'] do |db|
		db.name					= db_config['database']
		db.username				= db_config['username']
		db.password				= db_config['password']
		db.host					= db_config['host']
		db.port					= db_config['port']
		db.skip_tables			= []
		db.only_tables			= []
		db.additional_options	= []
	end

	notify_by Mail do |mail|
		mail.on_success		= true
		mail.on_failure		= true

		mail.from			= smtp_config['user']
		mail.to				= smtp_config['default_mail']
		mail.address		= smtp_config['server']
		mail.port			= smtp_config['port']
		mail.domain			= smtp_config['domain']
		mail.user_name		= smtp_config['user']
		mail.password		= smtp_config['password']
		mail.authentication	= smtp_config['authentication']
		mail.encryption		= :starttls
	end


	store_with Local do |local|
		local.path	= '/var/www/site/'
		local.keep	= 15
	end
end

Но насколько успешно непонятно. Как побороть?

        packages = yaml_load.unshift(package)

Почему то видит только один бекап...

Выяснилось то что каждый раз при деплое удалялся файл Local.yml. В этом файле записано какие бекапы уже делались. В общем свой косяк.
