NAME
Revert-DcsSnapshot
SYNOPSIS
Reverts the source virtual disk to the state of the snapshot. This operation can also be performed on a snapshot group.
SYNTAX
Revert-DcsSnapshot -Snapshot <Object> [ -Yes] [ -Connection <String> ] [ -PipelineVariable <String> ] [ -WhatIf] [ -Confirm]
Revert-DcsSnapshot -SnapshotGroup <Object> [ -Yes] [ -Connection <String> ] [ -PipelineVariable <String> ] [ -WhatIf] [ -Confirm]
DESCRIPTION
Reverts the source virtual disk to the state of the snapshot. This operation can also be performed on a snapshot group. Reverting will overwrite all changes that have occurred on the source virtual disk after the point-in-time of the snapshot. Before invoking this cmdlet, I/O from the client host should be stopped and the source virtual disk should be unserved from the client host, see Unserve-DcsVirtualDisk.

Get-DcsSnapshot | Revert-DcsSnapshot -Yes
The cmdlet Get-DcsSnapshot is invoked to obtain all SnapshotData objects for the server group. The objects are piped to Revert-DcsSnapshot resulting in the reverting of all snapshots in the server group. The Yes parameter is included to eliminate the need to confirm the operation.
