我需要从备份（AWS Snapshot）恢复我的jenkins配置。我有一个EC2实例，跟随并更新，丢失了jenkins配置。我的第一次尝试是将EC2 AMI恢复到更新前的点，但仍然缺少jenkins配置。
我们每晚都会拍摄jenkins的AWS快照。从这里我创建了一个卷并将其安装到EC2盒子上。我将它安装到/media/jenkins/并看到jenkins数据存在。它以37Gb进入。我在实例上重新安装了Jenkins并尝试将/var/lib/jenkins/符号链接到/media/jenkins/但是这会导致Too many levels of symbolic links
jenkins_home是37GB。 jenkins运行的EC2实例只有17 GB免费（它是一个40GB的盒子）。因此，我假设备份中的所有数据最初都不在盒子上。
我的问题是我需要将整个37GB复制到/ var / lib / jenkins /这似乎是一种蛮力的方法，还是有一种更明智的方法来恢复jenkins。
这是我的空jenkins配置

我认为你应该复制所有37 GB 这个时间。但是为了下一次尝试理解为什么你有37 GB的数据。 你可以忽略它包含的工作区文件夹，只包含要在Master上构建的临时文件。
检查是否存在历史记录太多并存档某些文件的问题构建，也许您可以减少数据。
另一种选择是开始使用瘦备份插件 - https://wiki.jenkins.io/display/JENKINS/thinBackup它可以备份所有配置。
另一个备份选项是使用https://wiki.jenkins.io/display/JENKINS/SCM+Sync+configuration+plugin，您可以在Github或任何其他源代码控制中保留所有配置/历史记录。
