KVM备份,如何?


徽章 +4
嗨,我在使用KVM时正在努力备份。我们一直在使用快照来进行标准备份过程,并且这些工作在集群中正常。我可以恢复VM作为一个新的克隆来检索丢失的文件,或者在发生重大崩溃的情况下直接替换原始的。



我的下一个问题是将这些快照导出到另一个集群(因为DR尚不可用于KVM)或非Nutanix档案服务器。这似乎是不可能的。到目前为止,我所建议的一切都涉及内部备份VM或使用DD复制ISCSI设备,这将涉及我们两个完全单独的备份过程并行运行。不好玩。



有没有办法将Nutanix驱动器导出到另一台服务器?从逻辑上讲,它们必须存在于某个地方,因此应该可以复制。

你好



你看过吗http://www.acronis.com/en-us/business/backup/linux-server/?



似乎是一个很好的KVM备份。

另一种方式 - 转储ISCSI磁盘,类似



dd if =/dev/disk/by-path/ip-122.168.5.2:3260-iscsi-iqn.2010-06.com.nutanix:hadoop-n001-disk1-1e386ef0-ef0-lun-0 of =/mnt/mnt/hadoop--n001.d1.img bs = 1m



您可以轻松找到所有磁盘从KVM主机中备份,类似



[root@ntnx-13smxxxxxxxx-a mnt]#ls/dev/disk/disk/by-path/* hadoop-n001th/dev/disk/disk/by-path/ip-path/ip-192.168.5.2:3260-iscssi-2010-2010-2010-2010-06。com.nutanix:hadoop-n001-cdrom-centos-6.5-x86_64-minimal.iso-70648f54-lun-0/dev/disk/by-path/ip-192.168.5.2:3260-iscsi-iqn.2010-06.com.nutanix:hadoop-n001-disk0-b3104834-lun-0/dev/disk/by-path/ip-192.168.5.2:3260-iscsi-iqn.2010-06.com.nutanix:hadoop-n001-disk1-1e386ef0-lun-0

通过此命令(在KVM Hypervisor上)获取与每个VM关联的磁盘路径的另一种方法




  1. 为您的VM获取UUID(通过Prism或下面的命令):VirSh列表 -

  2. 获取磁盘图像位置:#virsh domblklist
这样就是这样:





/dev/mapper/1nutanix_nfs_388663_d10d8f42_1fcc_4fd5_be30_006de14e340e





备份问题不是制作上述磁盘映像的副本。我尚未找到一种将其“恢复”回到雅典卫城管理的VM中的方法。有人想知道吗?似乎我们还需要VM XML配置(您也可以通过Virsh将其转储)。

你好nutanix用户,



对你来说是个好消息。在2018年初



此外,还有一个免费程序,它允许您免费保护10VM



//www.jhbzcj.com/partners/technology-alliance-program/storware/



我确实建议您查看我们的网页或观看45分钟的技术网络研讨会,我们在7月与Nutanix团队举办了:



https://www.youtube.com/watch?v=sy_nuth5-uy&feature=youtu.be



我们讨论了Storware和Nutanix如何提供提供的端到端解决方案:



- 使用CBT/CRT(更改区域跟踪)对AHV VM的高效,增量备份,

- 在AHV VM上运行的应用程序的数据一致性,

- 文件级从备份还原,

- 可扩展的多节点备份体系结构,

- 编排通过开放API。



请记住,Vprotect提供多个备份目的地,您可以将数据存储在多个备份目的地(备份目标)上☺️
