## Syntax
```
Stop-VBORepositorySynchronizeSession -Session <VBORepositorySynchronizeSession> [<CommonParameters>]
```

## Detailed Description

`<CommonParameters>`

This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see the [About Common Parameters](http://go.microsoft.com/fwlink/p/?LinkID=113216) section of Microsoft Learn.

## Output Object
The cmdlet returns the [`VBORepositorySynchronizeSession`](vborepositorysynchronizesession.md) object that contains details on the synchronization status of an object storage repository.

## Examples

::: example
### Example 1: Stopping All Synchronization Sessions

This command stops all sessions that are running to synchronize cache between object storage repositories and the *PersistentCache* database on the PostgreSQL instance.

```
Get-VBORepositorySynchronizeSession | foreach{Stop-VBORepositorySynchronizeSession -Session $_}
```

::: example
### Example 2: Stopping Specific Synchronization Session

This example shows how to stop a session that is running to synchronize cache between the *Azure* object storage repository and the *PersistentCache* database on the PostgreSQL instance.

```
$azurestorage = Get-VBORepository -Name "Azure"
$session = Get-VBORepositorySynchronizeSession -Repository $azurestorage
Stop-VBORepositorySynchronizeSession -Session $session
```

Perform the following steps:

1. Run the [`Get-VBORepository`](get-vborepository.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$azurestorage` variable.
2. Run the [`Get-VBORepositorySynchronizeSession`](get-vborepositorysynchronizesession.md) cmdlet. Set the `$azurestorage` variable as the `Repository` parameter value. Save the result to the `$session` variable.

   The cmdlet output will contain the following details on synchronization status of an object storage repository: `RepositoryId`, `RepositoryName` and `Status`.

3. Run the `Stop-VBORepositorySynchronizeSession` cmdlet. Set the `$session` variable as the `Session` parameter value.
