O059、Backup Volume 操作

参考https://www.cnblogs.com/CloudMan6/p/5662236.html

BackUp是将Volume备份到别的地方（备份设备），将来可以通过restore操作恢复。

BackUp VS Snapshot

查看backup功能好像与snapshot很相似，都可以保存volume的当前状态，以备以后恢复。但二者在用途和实现上还是有却别的，具体表现在：

1、Snapshot依赖于源volume，不能独立存在；而backup不依赖与源volume，即使源volume不存在了，也可以restore

2、Snapshot 与源volume 通常放在一起，都由同一个volume provider 管理；而backup存放在独立的备份设备中，有自己的备份方案和实现，与volume provider 没有关系。

3、上面两点决定了backup 具有容灾功能；而snapshot则提供volume provider内便捷的回溯功能

配置cinder-backup

Cinder 的Backup功能是由 cinder-backup 服务提供的，DevStack 默认没有启用该服务，需要手工启动。与cinder-volume类似，cinder-backup也通过driver架构支持多种备份backend，包括POSIX文件系统、NFS、Ceph、GlusterFS、Swift和IBM TSM。支持的driver 源文件放在/opt/stack/cinder/cinder/backup/drivers/目录下

[root@DevStack-Rocky-Compute-22 ~]# ll /opt/stack/cinder/cinder/backup/drivers/

total 132

本节以NFS为backend来研究backup操作。

在实验环境中，存放volume backup 的NFS 远程目录为 10.12.28.8:/home/nfs ，cinder-backup服务节点上挂载点为 /backup_mount 。需要在/etc/cinder/cinder.conf中进行配置

[DEFAULT]

backup_driver = cinder.backup.drivers.nfs

backup_mount_point_base = /backup_mount

backup_share = 10.12.28.8:/home/nfs

启动cinder-backup，第一次执行会报错，第二次就好了（第二次执行加 & ，这样不会占用终端）

/usr/bin/python /usr/bin/cinder-backup --config-file /etc/cinder/cinder.conf

目前只能在命令行执行backup操作（因为要执行backup的volume当前attach到了Instance上，所以需要添加--force选项，还可以添加 --incremental 选项执行增量备份）

cinder-backup执行backup过程分析：

1、启动backup操作，mount NFS

2、创建volume的临时快照，见上面backup过程中 cinder list 内容

3、创建存放backup的container目录

4、对临时快照进行数据压缩，并保存到container目录

5、创建并保存sha256（加密）文件和metadata文件

6、删除临时快照
