Use an account with the target resource permissions documented for Sync-SRGroup. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Supported environments

Windows / StorageReplica · Windows Server 2025 documentation; feature/module prerequisites apply

Parameters

-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-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.
-ComputerName: Specifies a single replica host computer NetBIOS name or fully qualified domain name (FQDN) of a computer for which this cmdlet syncs. The default value is the local computer.
-Force: Forces the command to run without asking for user confirmation.
-Name (required): Specifies the name of the replication group for which this cmdlet starts or resumes replication. If you pause replication, Storage Replica dismounts the volume. Applications and users cannot access this volume until you run Sync-SRGroup.
-ThrottleLimit: Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Prerequisites

Windows with the StorageReplica module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.

Security considerations

This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
