KVM备份，如何？

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，也可以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 Archival Server。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。

\nMy next problem is exporting those snapshots to another cluster (since DR isn't available for KVM yet) or to a non-Nutanix archival server. That appears not to be possible. Everything I've been suggested so far involves backing up the VM internally or copying the iSCSI device with dd which would involve us having two completely separate backup processes running in parallel. Not fun.
\n
\nIs there a way to export the Nutanix drives to another server? Logically they must exist somewhere so should be copyable.","quoteUsername":"kiboro","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

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-lun-0 of =/mnt/mnt/hadoop--n001.d1.img bs = 1m

您可以轻松从KVM主机找到所有备份的磁盘，就像

[root@ntnx-13smxxxxxxxx-a mnt]＃ls/dev/disk/disk/disk/path/* hadoop-n001th/dev/disk/disk/disk/by-path/ip-path/ip-192.168.5.2:3260-iscssi-2010-2010-2010-2010-06。。-1E386EF0-LUN-0
\n
\ndd if=\/dev\/disk\/by-path\/ip-192.168.5.2:3260-iscsi-iqn.2010-06.com.nutanix:hadoop-n001-disk1-1e386ef0-lun-0 of=\/mnt\/hadoop-n001.d1.img bs=1M
\n
\nYou can easely find all disks to backup from KVM host, something like
\n
\n[root@NTNX-13SMxxxxxx-A mnt]# ls \/dev\/disk\/by-path\/*hadoop-n001*\/dev\/disk\/by-path\/ip-192.168.5.2:3260-iscsi-iqn.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","quoteUsername":"shapa","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

通过此命令（在KVM Hypervisor上）获得与每个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
将是这样的：


/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转储它）。

  1. Get UUID for your VM (either through Prism or command below):virsh list --all \n \n
  2. Get disk image location:# virsh domblklist \n<\/ol>It will be something like this:

    \nProblem with backup is not making a copy of the above disk image. I have yet found a way to \"restore\" it back into acropolis-managed VM. Anyone figure this yet? Seems like we would also need the VM XML configuration (you can dump it via virsh as well).","quoteUsername":"vinnielima","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好nutanix用户，

对你来说是个好消息。在2018年初，您将在KVM中有一个新玩家，雅典卫城数据保护字段 - Storware Vprotect！

此外，还有一个免费程序，它允许您免费保护具有所有功能的10VM。

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

我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提供了多个备份目的地，您可以将数据存储在多个备份目的地（备份目标）上☺️：
