在Windows故障转移集群中创建VSS启用快照

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

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"}}}">

\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"}}}">

dlink7<\/a>,

\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"}}}">
