从另一个文件系统还原Jenkins备份

Question

我需要从备份(AWS快照)恢复jenkins配置。我有一个EC2实例，它跟踪和更新了jenkins配置。我的第一次尝试是将EC2 AMI恢复到更新之前的位置，但仍然缺少jenkins配置。

我们每晚拍一张詹金斯的AWS快照。由此，我创建了一个卷，并将其挂载到EC2框中。我把它装到/media/jenkins/上，看到詹金斯的数据就在那里。它的价格是37 It。我在实例上重新安装了Jenkins，并尝试将/var/lib/jenkins/链接到/media/jenkins/，但是这导致了Too many levels of symbolic links。

它是jenkins_home，它是37 It。jenkins运行的EC2实例只有17 GB空闲(它是一个40 GB的Box)。因此，我假设备份中的所有数据都不是最初放在框上的。

我的问题是，我是否需要将整个37 to复制到/var/lib/ jenkins / (这似乎是一种蛮力的方法)，还是有更明智的方法来恢复jenkins。

这是我空的jenkins配置

[10:43][ip-10-0-33-8:/var/lib/jenkins[1]]$ ls -la
total 8
drwxr-xr-x  2 root root 4096 Oct  4 12:06 .
drwxr-xr-x 27 root root 4096 Oct  4 11:04 ..

在备份挂载中

[10:43][ip-10-0-33-8:/media/jenkins[1]]$ ls -la
total 12
drwxr-xr-x  3 jenkins jenkins 4096 Oct  4 12:10 .

drwxr-xr-x 40 jenkins jenkins 4096 Sep 29 16:12 jenkins_home

在jenkins_home内部

Answer 1

我认为您应该在这个时间复制所有37 GB的。但是接下来请试着理解为什么您有37 GB的数据。您可以忽略它只包含要在Master上构建的临时文件的工作区文件夹。

检查是否有一些有问题的构建有太多的历史和归档一些文件，也许你可以减少数据。

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。

另一种备份选项是使用https://wiki.jenkins.io/display/JENKINS/SCM+Sync+configuration+plugin，您可以将所有配置/历史记录保存在Github或任何其他源代码管理中。
