Brian Lich|Last Updated: 3/8/2017

SYNOPSIS

Restores a virtual machine checkpoint.

SYNTAX

SnapshotName (Default)

Restore-VMSnapshot [-CimSession <CimSession[]>] [-ComputerName <String[]>] [-Credential <PSCredential[]>]
 [-Name] <String> [-VMName] <String> [-AsJob] [-Passthru] [-WhatIf] [-Confirm] [<CommonParameters>]

SnapshotObject

Restore-VMSnapshot [-VMSnapshot] <VMSnapshot> [-AsJob] [-Passthru] [-WhatIf] [-Confirm] [<CommonParameters>]

VM

Restore-VMSnapshot [-VM] <VirtualMachine> [-Name] <String> [-AsJob] [-Passthru] [-WhatIf] [-Confirm]
 [<CommonParameters>]

DESCRIPTION

The Restore-VMSnapshot cmdlet restores a virtual machine checkpoint.

Note: In Windows Server 2012 R2, virtual machine snapshots were renamed to virtual machine checkpoints. For clarity, this document will refer to virtual machine snapshots as checkpoints.

EXAMPLES

Example 1

PS C:\> Restore-VMSnapshot -Name 'Base image' -VMName TestVM
Confirm
Are you sure you want to perform this action?
Restore-VMSnapshot will restore checkpoint "Base image".
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help
(default is "Y"): Y

Restores checkpoint Base image of virtual machine TestVM.

Example 2

PS C:\> Get-VM | Foreach-Object { $_ | Get-VMSnapshot | Sort CreationTime | Select -Last 1 | Restore-VMSnapshot -Confirm:$false }

Applies the most recent checkpoint on all virtual machines with no confirmation prompts.

PARAMETERS

-AsJob

Runs the cmdlet as a background job.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type: CimSession[]
Parameter Sets: SnapshotName
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ComputerName

Specifies one or more Hyper-V hosts on which the virtual machine checkpoint is to be restored. NetBIOS names, IP addresses, and fully qualified domain names are allowable. The default is the local computer. Use localhost or a dot (.) to specify the local computer explicitly.

Type: String[]
Parameter Sets: SnapshotName
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False
Position: Named
Default value: False

Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Name

Specifies the name of the checkpoint to be restored.

Type: String
Parameter Sets: SnapshotName, VM
Aliases: 

Required: True
Position: 0
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Passthru

Specifies that a VMSnapshot is to be passed through to the pipeline representing the checkpoint to be restored.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

Aliases: 

Required: True
Position: 1
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-VMSnapshot

Specifies an array of VMSnapshot objects. To obtain a VMSnapshot object, use the Get-VMSnapshot cmdlet. The cmdlet restores the virtual machine checkpoints that you specify.

Type: VMSnapshot
Parameter Sets: SnapshotObject
Aliases: VMCheckpoint

Required: True
