 ## 功能
 每天从https://git.ociflab.icu/Laplace/backup-list拉取whitelist.md
+如果没拉取到，则使用前一天拉取并保存的whitelist文件。
+如果超过三分之一的仓库都拉取错误，则给脚本中设置的server酱3 Pushkey推送警告信息。
 然后根据whitelist.md拉取对应的仓库到backup文件夹进行备份
 压缩成zip，每天定时备份一次，保留7天。
-使用Python。
+使用bash。
 
 ## whitelist.md文件结构：
 
 ~~~
 https://git.ociflab.icu/userA/projectA
 https://git.ociflab.icu/userB/projectB
+~~~
+
+
+## server酱3参考
+~~~bash
+# 一行代码即可调用，中文参数需要UrlEncode，长内容建议使用POST
+curl "https://<uid>.push.ft07.com/send/<sendkey>.send?title=<title>&desp=<desp>"
