Velero 的简单介绍

Velero 是一个 vmware 开源的工具，用于 k8s 安全备份和恢复、执行灾难恢复以及迁移 Kubernetes 集群资源和持久卷。

Velero 可以做的：

• 备份集群并在丢失时恢复。
• 将集群资源迁移到其他集群。
• 将您的生产集群复制到开发和测试集群。

Velero 包括两部分：

• 在集群上运行的服务器(Velero 服务器)
• 在本地运行的命令行客户端(velero cli)

什么时候使用 Velero 代替 etcd 的内置备份/恢复是合适的？

关于 Velero 和 etcd 的快照备份如何选择？

我个人认为

• etcd 快照备份适用于比较严重的集群灾难。比如所有 etcd 集群所有节点宕机，快照文件丢失损坏的情况。k8s 集群挂掉的情况， etcd 备份恢复 是一种快速且成功率高的恢复方式，Velero 的恢复需要依赖其他组件，并且需要保证集群是存活的。
• Velero 适用于集群迁移，k8s 子集备份恢复，比如基于命名空间备份。某个命名空间误删，且 YAML 文件没有备份，那么可以 Velero 快速恢复。涉及多API资源对象 的系统升级，可以做升级前备份，升级失败通过 Velero 快速恢复。

Velero github 上面的解答：

Etcd 的备份/恢复工具非常适合从单个 etcd 集群中的数据丢失中恢复。例如，在升级 etcd istelf 之前备份 etcd 是个好主意。对于更复杂的 Kubernetes 集群备份和恢复管理，我们认为 Velero 通常是更好的方法。它使您能够扔掉不稳定的集群，并将您的 Kubernetes 资源和数据恢复到新的集群中，而仅通过备份和恢复 etcd 无法轻松做到这一点。

Velero 有用的案例示例：

• 您无权访问 etcd(例如，您在 GKE 上运行)
• 备份 Kubernetes 资源和持久卷状态
• 集群迁移
• 备份 Kubernetes 资源的子集
• 备份存储在多个 etcd 集群中的 Kubernetes 资源(例如，如果您运行自定义 apiserver)

灾备恢复原理简单介绍

这部分建议小伙伴官网了解 这里简单介绍

每个 Velero 操作——按需备份、计划备份、恢复——都是自定义资源，使用 Kubernetes 自定义资源定义 (CRD) 定义并存储在 etcd 中。Velero 还包括处理自定义资源以执行备份、恢复和所有相关操作的控制器。

备份工作流程

• 当你运行时 velero backup create test-backup
• Velero 客户端调用 Kubernetes API 服务器来创建一个 Backup 对象。
• BackupController 通知新对象Backup并执行验证。
• BackupController 开始备份过程。它通过查询 API 服务器的资源来收集要备份的数据。
• 调用对象存储服务(BackupController 例如 AWS S3)以上传备份文件。

默认情况下，velero backup create 为任何持久卷制作磁盘快照。您可以通过指定额外的标志来调整快照。运行 velero backup create --help 以查看可用标志。可以使用选项禁用快照 --snapshot-volumes=false。

恢复工作流程

• 当你运行时 velero restore create：
• Velero 客户端调用 Kubernetes API 服务器来创建一个 Restore 对象。
• RestoreController 通知新的 Restore 对象并执行验证。
• 从对象存储服务中 RestoreController 获取备份信息。然后它对备份的资源进行一些预处理，以确保这些资源可以在新集群上运行。例如，使用 备份的 API 版本来验证还原资源是否可以在目标集群上运行。
• RestoreController 启动还原过程，一次还原每个符合条件的资源。

默认情况下，Velero 执行非破坏性恢复，这意味着它不会删除目标集群上的任何数据。如果备份中的资源已存在于目标集群中，Velero 将跳过该资源。您可以将 Velero 配置为使用更新策略，而不是使用 --existing-resource-policy 恢复标志。当此标志设置为 时 update，Velero 将尝试更新目标集群中的现有资源以匹配备份中的资源。

服务端安装

在安装 服务端的同时，需要安装一个 存放 备份数据文件的对象存储系统 Minio

credentials-velero 在您的 Velero 目录中创建特定于 Velero 的凭据文件，用于连接 minio

启动服务器和本地存储服务。

本地存储服务部署

下面的 YAML 文件在 Velero 目录中，在上面的客户端的安装包里，解压出来就可以看到这个 Yaml 文件

这个 YAML 文件 用于部署一个从集群内访问的 Minio 实例。并且启动一个 Job 在 Minion 中建立备份需要的桶，需要在集群外部公开 Minio 服务。需要外部访问才能访问日志和运行 velero describe 命令。

修改下 yaml 文件，这里主要修改 Service 为 NodePort。并且把 Minion 的 控制台访问 IP 涉及为静态。

注意：Minio yaml 提供的示例使用“empty dir”。您的节点需要有足够的可用空间来存储正在备份的数据以及 1GB 的可用空间。如果节点没有足够的空间，您可以修改示例 yaml 以使用 Persistent Volume 而不是“empty dir”

• bucket：你在 minio 中创建的 bucketname
• backup-location-config: 把 xxx.xxx.xxx.xxx 改成你 minio 服务器的 ip 地址。

恢复失败情况分析

这里需要说明一点过，如果当前有命令空间发生了删除，但是你中断了它，类似下面这样，kubevirt 通过命令行发生的删除操作，但是它的删除没有完成。或者你进行了一些其他的操作。重复的删除创建 API 资源，导致的某些问题希望恢复操作之前的集群状态

┌──[root@vms100.liruilongs.github.io]-[~/ansible/kubevirt]
└─$kubectl get ns
NAME                 STATUS        AGE

kube-node-lease      Active        3d20h
kube-public          Active        3d20h

kubevirt             Terminating   3d20h
local-path-storage   Active        3d20h
metallb-system       Active        3d20h
velero               Active        40h

这个时候，如果使用 velero 发生 备份还原操作。可以会卡在下面的两个状态 InProgress 或者 New

如果长时间没有变化，需要把通过脚本把命名空间彻底删除，然后还原工作才可以正常进行
