# Set-VBRImmutabilityLockExpirationDate

## Short Description
Modifies immutability period of restore points located in a hardened repository.

::: important

This cmdlet does not support the following types of restore points:

- Restore points created by [unstructured data source jobs](working_unstructured_source.md).
- Restore points created by [application backup policies](plugin_management.md).
- Restore points for transaction logs.

:::

**Platform**: VMware, Hyper-V

**Product Edition**: Standard, Enterprise, Enterprise Plus, Veeam Universal License

## Syntax

This cmdlet provides the following parameter sets:

<ul class="syntax-sets">
  <li>
    <p><code>ExpirationDate (Default)</code></p>

```
Set-VBRImmutabilityLockExpirationDate [-RestorePoint] <COib[]> -ExpirationDate <DateTime> [<CommonParameters>]
```
  </li>
  <li>
    <p><code>Reset</code></p>

```
Set-VBRImmutabilityLockExpirationDate [-RestorePoint] <COib[]> [-ToOriginal] [<CommonParameters>]
```
  </li>
</ul>

## Detailed Description
This cmdlet modifies immutability period of restore points located in a hardened repository.

::: note

To modify settings, specify new values for the necessary parameters. The cmdlet will overwrite the previous parameter values with new values. The parameters that you omit will remain unchanged.

:::

::: important

It is not possible to reduce immutability via PowerShell commands. After you set the value, you can either extend it or reset back to the original value. However, you cannot set it to a smaller value than was originally set.

`<CommonParameters>`

This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see [ Microsoft Docs](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_commonparameters?view=powershell-7).

## Output Object
The cmdlet returns the `VBRImmutabilityLockExpirationDate` object that contains immutability period of of restore points located in hardened repository with immutability.

## Examples

::: example
### Example 1. Extending Immutability Period of the Latest Restore Point in a Chain

This example shows how to change the immutability lock expiration date for the most recent incremental restore point in a backup chain. The cmdlet applies the new expiration date to the whole active chain that contains this restore point.

```
$backup = Get-VBRBackup -Name "example backup"
$rp = Get-VBRRestorePoint -Backup $backup
$date = Get-Date -Year 2023 -Month 2 -Day 3 -Hour 0 -Minute 0 -Second
Set-VBRImmutabilityLockExpirationDate -RestorePoint $rp[-1] -ExpirationDate $date
```

Perform the following steps:

1. Run the [`Get-VBRBackup`](get-vbrbackup.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$backup` variable.
2. Run the [`Get-VBRRestorePoint`](get-vbrrestorepoint.md) cmdlet. Specify the `$backup` variable as the `Backup` parameter value. Save the result to the `$rp` variable.
3. Run the [`Get-Date`](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/get-date?view=powershell-7.1) cmdlet. Specify the `Year`, `Month`, `Day`, `Hour`, `Minute` and `Second` parameter values. Save the result to the `$date` variable.
4. Run the `Set-VBRImmutabilityLockExpirationDate` cmdlet. Specify `$rp[-1]` as the `RestorePoint` parameter value. Specify the `$date` variable as the `ExpirationDate` parameter value.

:::

::: example
### Example 2. Resetting Immutability Period of Restore Points

This examples shows how to reset immutability period of restore points. The cmdlet will set the immutability to the time period that was originally specified for the hardened repository.

```
$restorepoint = Get-VBRRestorePoint
Set-VBRImmutabilityLockExpirationDate -RestorePoint $restorepoint -ToOriginal
```

Perform the following steps:

1. Run the [`Get-VBRRestorePoint`](get-vbrrestorepoint.md) cmdlet. Save the result to the `$restorepoint` variable.
2. Run the `Set-VBRImmutabilityLockExpirationDate` cmdlet. Set the `$restorepoint` variable as the `RestorePoint` parameter value. Provide the `ToOriginal` parameter.
