我有几个VM构建Windows故障转移群集。共享存储由使用iSCSI连接到VM的NDFS卷组提供。
可以创建启用此群集的VSS快照吗？

    你好josegerez.

    我们还不支持使用iSCSI和卷组创建基于App-Consionent（VSS）的Nutanix的快照。

    谢谢，

    \nWe don't yet support creating app-consistent (VSS) Nutanix based snapshots with iSCSI and volume groups.

    谢谢mmcghee.。

    因此，没有办法在用VM构建的Windows群集中具有应用程序一致的快照？

    \nSo, there's no way to have app-consistent snapshots in a windows cluster built with vms? 😞","quoteUsername":"josegerez","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    不是我所知道的nutanix快照josegerez.今天至少没有本地，但让我们更详细地探索。

    您能否描述您的申请和恢复要求？在需要时间点（快照时间）恢复的情况下，如果不是更好的imho，则依赖写一致的快照工作也是如此。Nutanix通过我们的亮相过程来确保Quescing写入依赖写一致性。

    VSS样式快照要求通常绑定在完整快照和增量日志或差异备份之间协调恢复到快照。在这里，VSS是一个硬要求。常用方案使用快照将SQL数据库恢复为加载状态（无恢复或备用），然后应用日志备份。要使用日志恢复样式恢复备份，备份例如commvault等第三方。我必须推迟Dlink7.或者其他关于commvault是否可以与卷组快照合作的其他人。我不认为这是可能的，但我并不完全肯定。
    josegerez<\/a> at least not natively today, but let's explore in more detail.
    \n
    \nCould you please describe your application and recovery requirements? In cases where point-in-time (time of snapshot) recovery is required, dependent-write consistent snapshots work just as well if not better IMHO. Nutanix ensures dependent-write consistency by quiescing writes through our stargate process.
    \n
    \nVSS style snapshot requirements generally tie into coordinating recovery between a full snapshot and incremental log or differential backups taken asynchronously to the snapshot. Here, VSS is a hard requirement. A common scenario is using a snapshot to recover a SQL database into a loading state (no recovery or standby), and then applying log backups. To get restore with log recovery style backups a third party like Commvault for example would be required. I'd have to defer dlink7<\/a> or others on whether Commvault can leverage VSS in conjunction with volume group snapshots. I don't think it's possible but I'm not entirely sure.","quoteUsername":"mmcghee","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    我必须做一些挖掘，但我不认为commvault今天可以看到卷组。

    你好，我们又见面了，mmcghee.
    嗯，我们正试图用Nutanix替换NetApp文件。
    在此文件管理器中，我们正在使用NAS服务（通过CIFS）向Windows客户端提供文件服务，但此时的AFS没有文件夹或文件筛选。所以，我们认为提供带有Windows文件服务器VM的文件服务，但没有群集它，我们可以在Windows维护期间提供HA（您知道，星期二修补:(）
    在这里我们需要VSS的地方。我们为NAS文件管理器提供了NetApp的先前版本功能。

    此外，我们正在使用文件管理器向LUN提供一堆物理SQL Server集群，并使用CommVault IntellIsnap功能进行备份。
    我们希望使用ABS向这些群集提供iSCSI LUN，而不会丢失基于快照的备份。
    mmcghee<\/a>
    \nWell, we're trying to replace a netapp filer with Nutanix.
    \nIn this filer we're using NAS services (via CIFS) to offer file services to windows clients, but AFS at this point has no quota by folder nor file screening. So, we think to offer file services with a windows file server vm but without clustering it we can provide HA during Windows maintenance (you know, tuesday patching :()
    \nAnd here is where we need vss. We're providing previous versions feature of Netapp to the NAS filer.
    \n
    \nAlso, we're using the filer to provide LUNs to a bunch of physical SQL Server clusters and doing backup with Commvault IntelliSnap feature.
    \nWe want use ABS to provide iSCSI LUNs to these clusters without losing the snapshot based backup.","quoteUsername":"josegerez","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    什么是文件筛选？AV？用户今天可以使用AFS恢复Windows以前版本的Windows文件。

    一世Dlink7.那

    文件筛选是用于阻止所选文件夹中某些文件类型（视频，音频，PST，....）的功能。
    Windows有内置。NetApp需要一个第三方工具来管理它。

    我知道AFS有Windows以前的版本支持，但它没有配额文件夹，也没有文件筛选，我们需要它们。
    只要我知道在AFS中，服务器VM使用iSCSI连接到存储数据的卷组。这是一个类似的配置，我正在追求，但是用Windows机器。

    \n
    \nfile screening is the feature used to block certain file types (video, audio, pst's, ....) in selected folders.
    \nWindows has it builtin. Netapp needs a 3rd party tool to manage it.
    \n
    \nI know AFS has Windows previous versions support, but it hasn't quota by folder nor file screening and we need them.
    \nAs long as i know in AFS the server vm's use iSCSI to connect to volume groups storing data. It's a similar config I'm taking about but with windows machines.","quoteUsername":"josegerez","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
