Resume-BitsTransfer

Updated: October 28, 2009

Applies To: Windows PowerShell 2.0

Resumes a Background Intelligent Transfer Service (BITS) transfer job.

Syntax

Resume-BitsTransfer [-BitsJob] <BitsJob[]> [-Asynchronous] [-Confirm] [-WhatIf] [<CommonParameters>]

Description

The Resume-BitsTransfer cmdlet resumes one or more suspended BITS transfer jobs. If the BITS transfer is already in process, the cmdlet does nothing. You can view the current state of a transfer job by using the Get-BitsTransfer cmdlet.

Important: By default, the Resume-BitsTransfer cmdlet restarts the transfer job synchronously even if the original job was specified as an asynchronous transfer job. You could use this behavior to convert an asynchronous transfer job into a synchronous transfer job. You could do this if either of the following conditions is true:

- The asynchronous transfer job was created outside cmdlets.

- The asynchronous transfer job was created by using the Start-BitsTransfer cmdlet.

If you want to restart the transfer job as an asynchronous transfer, use the Asynchronous parameter.

Parameters

-Asynchronous

Allows the BITS transfer job to be processed in the background. The command prompt reappears immediately after the BITS transfer job is resumed. The returned BitsJob object can be used to monitor status and progress.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see about_CommonParameters.

Inputs and Outputs

The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet returns.

 

Inputs

Microsoft.BackgroundIntelligentTransfer.Management.BitsJob[]

This cmdlet accepts one or more BitsJob objects as input that populates the BitsJob parameter.

Outputs

Microsoft.BackgroundIntelligentTransfer.Management.BitsJob[]

When called with the Asynchronous parameter, this cmdlet sends the BitsJob object that is associated with the resumed BITS transfer job as output. Otherwise, no output is generated.

Notes

You can cancel a transfer job that is running in synchronous mode (foreground priority) by pressing CTRL+C.

Example 1

C:\PS>Get-BitsTransfer | Resume-BitsTransfer

Description
-----------
This command resumes all the BITS transfer jobs that are owned by the current user. 

The command prompt returns after the jobs are complete or after the jobs enter an error state. The output of the Get-BitsTransfer cmdlet is a set of BitsJob objects. This output is piped to the Resume-BitsTransfer cmdlet. If any of the BITS transfer jobs are already active, they will continue to run.







Example 2

C:\PS>$b = Start-BitsTransfer -DisplayName "MyJob" -Suspended
Add-BitsTransfer -BitsJob $b -ClientFileName C:\myFile -ServerFileName http://www.mysite.com/file1
Resume-BitsTransfer -BitsJob $b -Asynchronous

Description
-----------
This command resumes a new BITS transfer job that was initially suspended, and it returns the command prompt immediately.

The first command creates a new BitsJob object in a suspended state and then stores it in the $b variable.

The second command adds a file to the transfer queue of the new BitsJob object that is stored in the $b variable.

The third command uses the BitsJob parameter to pass the BitsJob object that is stored in the $b parameter to the Resume-BitsTransfer cmdlet. This command starts the BITS transfer job.







Example 3

C:\PS>Get-BitsTransfer -Name testjob1 | Resume-BitsTransfer

Description
-----------
This command resumes the BITS transfer that is identified by the specified display name. 

The command prompt returns after the job is complete or after the job enters an error state. The output of the Get-BitsTransfer cmdlet is a BitsJob object. This output is piped to the Resume-BitsTransfer cmdlet. If the BITS transfer job is already active, it will continue to run.
