脚本功能

服务的备份脚本，功能是保留7天的备份数据，并且将最新的备份数据拷贝到备份盘

#!/usr/bin/env python# coding: utf-8import osimport datetimeimport shutil# confluence数据备份，因为confluence不能保留7天备份，并且每天全备份，占用空间很大，所以写脚本，保留7天备份文件。data_directory = "/data/var/atlassian/application-data/confluence/backups/"backup_directory = "/backup/"# backup file name: backup-2019_02_24.ziptoday_backup_file = "backup-" + str(datetime.date.today() + datetime.timedelta(days = -1)).replace("-", "_") + ".zip"day_list = []for i in range(1, 8):    day = str(datetime.date.today() + datetime.timedelta(days = -i)).replace("-", "_")    filename = "backup-" + day + ".zip"    day_list.append(filename)if os.path.exists(data_directory) and os.path.exists(backup_directory):    # 循环数据目录，将7天的数据文件保留，其他的删除，并将最新的数据备份包，拷贝到其他的盘上        for file in os.listdir(data_directory):        filepath = os.path.join(data_directory, file)        if file == today_backup_file:            shutil.copy(filepath, backup_directory)        elif file not in day_list:            file = os.remove(filepath)
