Create - powershell.one

Creates a differential area storage for the specified Volume.

Example

Do not run below example code just to see what happens next. Many methods seriously affect your system. Always make sure you actually understand what the method and the code do.

# define the arguments you want to submit to the method
# remove values that you do not want to submit
# make sure you replace values with meaningful content before running the code
# see section "Parameters" below for a description of each argument.
$arguments = @{
    DiffVolume      = 'someText'  # replace 'someText' with meaningful text
    MaxSpace        = [UInt64](12345)  # replace 12345 with a meaningful value
    Volume          = 'someText'  # replace 'someText' with meaningful text
}


Invoke-CimMethod -ClassName Win32_ShadowStorage -Namespace Root/CIMV2 -MethodName Create -Arguments $arguments |
Add-Member -MemberType ScriptProperty -Name ReturnValueFriendly -Passthru -Value {
  switch ([int]$this.ReturnValue)
  {
        0        {'Success'}
        default  {'Unknown Error '}
    }
}

To run this method on one or more remote systems, use New-CimSession:

$ComputerName = 'server12','server14'  # adjust to your server names
$Credential   = Get-Credential         # submit a user account with proper permissions

# define the arguments you want to submit to the method
# remove values that you do not want to submit
# make sure you replace values with meaningful content before running the code
# see section "Parameters" below for a description of each argument.
$arguments = @{
    DiffVolume      = 'someText'  # replace 'someText' with meaningful text
    MaxSpace        = [UInt64](12345)  # replace 12345 with a meaningful value
    Volume          = 'someText'  # replace 'someText' with meaningful text
}


$session = New-CimSession -ComputerName $ComputerName -Credential $Credential

Invoke-CimMethod -ClassName Win32_ShadowStorage -Namespace Root/CIMV2 -MethodName Create -Arguments $arguments -CimSession $session |
Add-Member -MemberType ScriptProperty -Name ReturnValueFriendly -Passthru -Value {
  switch ([int]$this.ReturnValue)
  {
        0        {'Success'}
        default  {'Unknown Error '}
    }
}

Syntax

uint32 Create(
  [in] string Volume,
  [in] string DiffVolume,
  [in] uint64 MaxSpace
);

Parameters

Name	Type	Description
DiffVolume	String	This parameter is the volume to be used to store the shadow differential area. If this paramter is not supplied the specified Volume will be used to store the differential area. This parameter can be specified as a volume drive letter, mount point or volume GUID name.
MaxSpace	UInt64	This parameter is the initial maximum size of the differential area.
Volume	String	This parameter is the volume that is to be shadowed. This parameter can be specified as a volume drive letter, mount point or volume GUID name.

Return Value

Returns a value of type UInt32. Return values:

$returnValues = @{
    0    = 'Success'
}

Requirements

To use Win32_ShadowStorage, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

Win32_ShadowStorage was introduced on clients with None supported and on servers with Windows Server 2003.

Namespace

Win32_ShadowStorage lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.

Implementation

Win32_ShadowStorage is implemented in Vsswmi.dll and defined in Vss.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\Vss.mof
