# RemoveWeeklySnapshot Vmware 虚拟机自动化程序：自动化导出虚拟机和快照信息，自动化删除旧快照。 ## Todo List - [x] Yaml 文件保存配置信息 - [x] 通过 Yaml 文件信息连接vCenter/Esxi - [x] 文件获取所有 vms - [x] 获取所有 snapshots - [x] 筛选出15天（半个月）前的 snapshots - [x] 以上内容以 Excel 表格的形式导出，超出 15 天的快照蓝色底填充标识 - [x] 最后删除 15 天前的 snapshot，并同时记录删除的 snapshot 日志信息 - [x] 设置计划任务，每周六（或 每15 天）执行一次 - [ ] 增加排除不能删除的 snapshots 信息，用红色底填充标识 - [ ] 删除快照前/后发送邮件通知 - [ ] 多线程删除（控制每台 vCenter 不可以同时删除超过 4 个快照） - [ ] 改用数据库保存管理节点账号密码（加密） ## 输出所有可用的属性和方法 | 你想获取 | 代码 | 示例输出 | | ------------ | ----------------------------------- | ---------------------------------------------- | | **名称**
