snapshots and dynamic disks

[mdangel1]

All,

VMware documentation states the following:

• You cannot revert to a snapshot with dynamic disks, so quiesced snapshots are not used when you restore dynamic disks. Snapshot technology has no visibility into Dynamic Disks. Dynamic Disks are commonly known as Microsoft specific file systems.

Dies this mean they are not supported at all, or just quiesced snapshots are not supported? What confuses me is the snapshot technoloy has no visibility to Dynamic disks.

Well , this need to be corrected .

As per vmware :

Do not use VMware snapshots to backup Dynamic Disks. If you take a snapshot of a Dynamic Disk (Microsoft specific file system), you will not be able to revert to the snapshot. Snapshot technology does not have visibility into dynamic disks and cannot preserve the quiesce state of the disk files.

Read this: VMware vSphere 5.1

So the overall output is no Snapshot will be supported in the Dynamic Disks as the state called "quiesced"  will not be effect and cant make any changes it while doing the revert of snapshot.

Hope you got it .

Thanks
