您好，在使用KVM时，我正在处理备份问题。我们一直在标准备份过程中使用快照，它们在集群中工作得很好。我可以恢复一个虚拟机，作为一个新的克隆检索丢失的文件，或直接替换原始的情况下，一个重大的崩溃。

我的下一个问题是将这些快照导出到另一个集群(因为KVM还不能使用DR)或导出到一个非nutanix存档服务器。这似乎是不可能的。到目前为止，我所建议的一切都涉及到内部备份VM或使用dd复制iSCSI设备，这将涉及到我们有两个完全独立的备份进程并行运行。不好玩。

有没有办法将Nutanix驱动器导出到另一个服务器?从逻辑上讲，它们必须存在于某个地方，所以应该是可复制的。

\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

你有没有看过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

弟弟如果= / dev /磁盘/子目录/ ip - 192.168.5.2:3260 iscsi iqn.2010 - 06. com.nutanix: hadoop-n001-disk1-1e386ef0-lun-0 = / mnt / hadoop-n001.d1。img b = 1米

您可以很容易地从KVM主机找到要备份的所有磁盘，类似这样

[root@NTNX-13SMxxxxxx-A mnt] # ls/dev/disk/by-path/ * hadoop-n001 * / dev /磁盘/子目录/ ip - 192.168.5.2:3260 iscsi iqn.2010 - 06. com.nutanix: hadoop - n001 cdrom - centos 6.5 - x86_64 minimal.iso - 70648 - f54 lun - 0 / dev /磁盘/子目录/ ip - 192.168.5.2:3260 iscsi iqn.2010 - 06. - com.nutanix: hadoop-n001-disk0-b3104834-lun-0 / dev /磁盘/子目录/ ip - 192.168.5.2:3260 iscsi iqn.2010 - 06. com.nutanix: hadoop-n001-disk1-1e386年ef0-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"}}}">

获取与每个vm关联的磁盘路径的另一种方法是通过这个命令(在KVM管理程序上)

  1. 获取虚拟机的UUID(通过Prism或下面的命令):virsh list——all
  2. 获取磁盘映像位置:# virsh domblklist
它会是这样的:


/dev/mapper/1NUTANIX_NFS_388663_d10d8f42_1fcc_4fd5_be30_006de14e340e


备份的问题是没有复制上述磁盘映像。我还没有找到一种方法来“恢复”它回到acropolis管理的虚拟机。有人想出来了吗?似乎我们还需要VM XML配置(您也可以通过virsh转储它)。

    \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?

你好Nutanix用户,

这对你来说是个好消息。在2018年初，您在KVM, Acropolis数据保护领域有了一个新的玩家- Storware vProtect !

此外，还有一个免费的程序，可以免费保护所有特性的10个虚拟机。

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

我建议你看看我们的网页或观看一个45分钟的技术网络研讨会，这是我们在7月与Nutanix团队举行的:

https://www.youtube.com/watch?v=SY_nUtH5-UY&feature=youtu.be

我们讨论了Storware和Nutanix如何提供端到端的解决方案:

-使用CBT/CRT (Changed-Region Tracking)对AHV虚拟机进行高效增量备份，
- AHV虚拟机上运行的应用程序的数据一致性，
-文件级恢复从备份，
-可扩展的多节点备份架构，
-通过开放API编排。

请记住，vProtect提供了几个备份目的地，您可以将您的数据存储在多个备份目的地(备份目标)☺️:

有很多备份选项 @kiboro

看看Veeam，HYCU,或Rubrik

看看Nutanix社区播客的这一集，你会有一些想法:
近同步复制:减少RPO时间
