[<CommonParameters>] Description
The Start-BitsTransfer cmdlet creates a Background Intelligent Transfer Service (BITS) transfer job to transfer one or more files between a client computer and a server. The TransferType parameter specifies the direction of the transfer. By default, after the cmdlet begins the transfer, the command prompt is not available until the transfer is complete or until the transfer enters an error state. If the state of the returned BitsJob object is Error, the error code and description are contained in the object and can be used for analysis.
The Start-BitsTransfer cmdlet supports the download of multiple files from a server to a client computer, but it does not generally support the upload of multiple files from a client computer to a server. If you need to upload more than one file, you can use the Import-Csv cmdlet to pipe the output to the Add-BitsFile cmdlet to upload multiple files. Or, if you need to upload more than one file, consider a cabinet file (.cab) or a compressed file (.zip).
Examples
Example 1: Create a BITS transfer job that downloads a file
PS C:\> Start-BitsTransfer -Source "http://server01/servertestdir/testfile1.txt" -Destination "c:\clienttestdir\testfile1.txt"This command creates a BITS transfer job that downloads a file from a server.
The local and remote names of the file are specified in the Source and Destination parameters.
Because the default transfer type is Download, the http://Server01/servertestdir/testfile1.txt file is transferred to C:\clienttestdir\testfile1.txt on the client.
The command prompt returns when the file transfer is complete or when it enters an error state.
When you upload files to an HTTP location, the TransferType parameter must be set to Upload.
Because the Start-BitsTransfer cmdlet assumes that the first parameter is the source and that the second parameter is the destination when no value is specified, this command could be simplified as follows:
Start-BitsTransfer "http://server01/servertestdir/testfile1.txt" "c:\clienttestdir\testfile1.txt"
Example 2: Create BITS transfer jobs that download multiple files
PS C:\> Import-CSV filelist.txt | Start-BitsTransferThis command creates BITS transfer jobs that download multiple files from a server.
The command imports the source and destination file locations and then pipes the locations to the Start-BitsTransfer command.
The Start-BitsTransfer command creates a new BITS transfer job for each of the files in filelist.txt and then transfers them concurrently to the client.
The contents of the filelist.txt file resemble the following information:
Source, Destination http://server01/servertestdir/testfile1.txt, c:\clienttestdir\testfile1.txt http://server01/servertestdir/testfile2.txt, c:\clienttestdir\testfile2.txt http://server01/servertestdir/testfile3.txt, c:\clienttestdir\testfile3.txt http://server01/servertestdir/testfile4.txt, c:\clienttestdir\testfile4.txt
Note: First line of the file must include Source, Destination header as in the example.
Example 3: Create a BITS transfer job that uploads a file
PS C:\> Start-BitsTransfer -Source "c:\clienttestdir\testfile1.txt" -Destination "http://server01/servertestdir/testfile1.txt" -TransferType UploadThis command creates a BITS transfer job that uploads a file to a server.
The local and remote names of the file are specified in the Source and Destination parameters.
Because the default transfer type is Download, the TransferType parameter must be set to Upload.
The C:\clienttestdir\testfile1.txt file on the client is transferred to http://Server01/servertestdir/testfile1.txt.
The command prompt returns when the file transfer is complete or enters an error state.
The Start-BitsTransfer cmdlet downloads multiple files from a server to a client computer, but it does not typically upload multiple files from a client computer to a server. It is possible to work around this limitation by using the Import-Csv cmdlet to pipe the output to the Start-BitsTransfer cmdlet. If you need to upload more than one file, you can also use a .cab or .zip file.
Because the Start-BitsTransfer cmdlet assumes that the first parameter is the source and that the second parameter is the destination when no value is specified, this command could be simplified as follows:
Start-BitsTransfer "c:\clienttestdir\testfile1.txt" "http://server01/servertestdir/testfile1.txt" -TransferType Upload
Example 4: Create a BITS transfer job that downloads multiple files
PS C:\> Start-BitsTransfer -Source "http://server01/servertestdir/testfile1.txt", "http://server01/servertestdir/testfile2.txt" -Destination "c:\clienttestdir\testfile1.txt", "c:\clienttestdir\testfile2.txt"This command creates a BITS transfer job that downloads multiple files from a server.
The local and remote names of the files are specified in the Source and Destination parameters.
Because the default of the TransferType parameter is Download, the http://Server01/servertestdir/testfile1.txt and http://Server01/servertestdir/testfile2.txt files are transferred to C:\clienttestdir\testfile1.txt and C:\clienttestdir\testfile2.txt on the client computer.
The command prompt returns when the file transfer is complete or enters an error state.
Example 5: Create a BITS transfer job that downloads a file using a specific set of credentials
PS C:\> $Cred = Get-Credential
PS C:\> Start-BitsTransfer -DisplayName MyJob -Credential $Cred -Source "http://server01/servertestdir/testfile1.txt" -Destination "c:\clienttestdir\testfile1.txt"This example creates a BITS transfer job that downloads a file from a server by using a specific set of credentials.
The first command retrieves a set of credentials from the user by calling the Get-Credential cmdlet. The returned PSCredential object is stored in the $Cred variable.
The second command uses the Credential parameter to pass the PSCredential object that is stored in the $Cred variable to the Start-BitsTransfer cmdlet.
A new BITS transfer job is created that downloads the http://server01/servertestdir/testfile1.txt file to the client.
The specified credentials are used to authenticate the user at the server.
Additionally, the optional DisplayName parameter is used to give the BITS transfer job a unique name.
Example 6: Create BITS transfer jobs that download multiple files
PS C:\> Import-CSV filelist.txt | Start-BitsTransfer -Asynchronous -Priority NormalThis command creates BITS transfer jobs that download multiple files from a server. The files are downloaded sequentially, but they are available immediately when the transfer job is complete.
The command imports the source and destination file locations and then pipes them to the Start-BitsTransfer command. The Start-BitsTransfer command creates a new BITS transfer job for each of the files in filelist.txt and then transfers them sequentially to the client.
The contents of the filelist.txt file resemble the following information:
Source, Destination http://server01/servertestdir/testfile1.txt, c:\clienttestdir\testfile1.txt http://server01/servertestdir/testfile2.txt, c:\clienttestdir\testfile2.txt http://server01/servertestdir/testfile3.txt, c:\clienttestdir\testfile3.txt http://server01/servertestdir/testfile4.txt, c:\clienttestdir\testfile4.txt
Note: First line of the file must include Source, Destination header as in the example.
Example 7: Create a BITS transfer job that downloads multiple files
PS C:\> Start-BitsTransfer -Source C:\clientsourcedir\*.txt -Destination c:\clientdir\ -TransferType DownloadIn the preceding example, the Start-BitsTransfer command creates a new BITS transfer job. All of the files are added to this job and transferred sequentially to the client.
Note
The destination path cannot use wildcard characters. The destination path supports relative directories, root paths, or implicit directories (that is, the current directory). Destination files cannot be renamed by using a wildcard character. Additionally, HTTP and HTTPS URLs do not work with wildcards. Wildcards are only valid for UNC paths and local directories.
Example 8: Create BITS transfer jobs that upload multiple files
PS C:\> Import-CSV filelist.txt | Start-BitsTransfer -TransferType UploadThis command creates BITS transfer jobs that upload multiple files to a server.
The command imports the source and destination file locations and then pipes them to the Start-BitsTransfer command. The Start-BitsTransfer command creates a new BITS transfer job for each of the files in filelist.txt and then transfers them concurrently to the server.
The contents of the filelist.txt file resemble the following information:
Source, Destination c:\clienttestdir\testfile1.txt, http://server01/servertestdir/testfile1.txt c:\clienttestdir\testfile2.txt, http://server01/servertestdir/testfile2.txt c:\clienttestdir\testfile3.txt, http://server01/servertestdir/testfile3.txt c:\clienttestdir\testfile4.txt, http://server01/servertestdir/testfile4.txt
Note: First line of the file must include Source, Destination header as in the example.
Example 9: Download a file from a server on a network to a client on a different network that are connected by a proxy server
PS C:\> Start-BitsTransfer -Source .\Patch0416.msu -Destination $env:temp\Patch0416.msu -ProxyUsage Override -ProxyList BitsProxy:8080 -ProxyCredential Server01\Admin01This command uses the Start-BitsTransfer cmdlet to copy a patch file from a server on one network to a client on a different network when the networks are connected only by a proxy server.
This scenario arises when an Internet-connected server downloads files and then distributes them to computers on disconnected or isolated networks that have no Internet access.
BITS can detect proxy server settings automatically. However, if the proxy servers are not configured for automatic detection, you can override the automatic detection mechanism and identify the proxy server explicitly, as shown in this example.
The command uses the Source parameter to specify the location of the patch on the server computer and the Destination parameter to specify the intended location of patch on the client computer.
It uses the ProxyUsage parameter with a value of Override to override the automatic proxy server detection mechanism.
To identify the proxy server, it uses the ProxyList parameter.
The value of the ProxyList parameter is a URI with a <Name:Port> format.
Finally, it uses the ProxyCredential parameter to specify the credentials of an administrator who has permission to connect to the proxy server.

-Priority
Sets the priority of the BITS transfer job, which affects bandwidth usage. The acceptable values for this parameter are:
Foreground (default): Transfers the job in the foreground. Foreground transfers compete for network bandwidth with other applications, which can impede the user's overall network experience. However, if the Start-BitsTransfer cmdlet is being used interactively, this is likely the best option. This is the highest priority level.
High: Transfers the job in the background with a high priority. Background transfers use the idle network bandwidth of the client computer to transfer files.
Normal: Transfers the job in the background with a normal priority. Background transfers use the idle network bandwidth of the client computer to transfer files.
Low: Transfers the job in the background with a low priority. Background transfers use the idle network bandwidth of the client to transfer files. This is the lowest background priority level.
| Type: | String |
| Accepted values: | Foreground, High, Normal, Low |
| Position: | Named |
| Default value: | Foreground |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ProxyAuthentication
Specifies the authentication mechanism to use at the Web proxy. The acceptable values for this parameter are:
Basic: Basic is a scheme in which the user name and password are sent in clear-text to the server or proxy.
Digest: Digest is a challenge-response scheme that uses a server-specified data string for the challenge.
Ntlm: NTLM is a challenge-response scheme that uses the credentials of the user for authentication in a Windows-based network environment.
Negotiate (the default): Negotiate is a challenge-response scheme that negotiates with the server or proxy to determine which scheme to use for authentication. For instance, this parameter value allows negotiation to determine whether the Kerberos protocol or NTLM is used.
Passport: Passport is a centralized authentication service provided by Microsoft that offers a single logon for member sites.

| Accepted values: | Basic, Digest, Ntlm, Negotiate, Passport |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ProxyBypass
Specifies a list of host names to use for a direct connection. The hosts in the list are tried in order until a successful connection is achieved. If you specify this parameter the cmdlet bypasses the proxy. If this parameter is used, the ProxyUsage parameter must be set to Override; otherwise, an error occurs.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ProxyCredential
Specifies the credentials to use to authenticate the user at the proxy. You can use the Get-Credential cmdlet to create a value for this parameter.
| Type: | PSCredential |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ProxyList
Specifies a list of proxies to use. The proxies in the list are tried in order until a successful connection is achieved. If this parameter is specified and ProxyUsage is set to a value other than Override, the cmdlet generates an error.
| Type: | Uri[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ProxyUsage
Specifies the proxy usage settings. The acceptable values for this parameter are:
SystemDefault (the default): Use the system default proxy settings.
NoProxy: Do not use a proxy to transfer files. Use this option when you transfer files within a local area network (LAN).
AutoDetect: Automatically detect proxy settings. BITS detects proxy settings for each file in the job.
Override: Specify the proxies or servers to use. If the ProxyList parameter is also specified, the proxies in that list are used. If the ProxyBypass parameter is also specified, the servers in that list are used. In both cases, the first member of the list is used. If the first member is unreachable, the subsequent members are tried until a member is contacted successfully.
| Type: | String |
| Accepted values: | SystemDefault, NoProxy, AutoDetect, Override |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-RetryInterval
Specifies the minimum length of time, in seconds, that BITS waits before an attempt to transfer the file after BITS encounters a transient error. The minimum allowed value is 60 seconds. If this value exceeds the RetryTimeout value from the BitsJob object, BITS does not retry the transfer. Instead, BITS sets the state of the BITS transfer job to the Error state.
The default is 600 seconds (10 minutes).
| Type: | Int32 |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-RetryTimeout
Specifies the length of time, in seconds, that BITS attempts to transfer the file after the first transient error occurs.
Setting the retry period to 0 prevents retries and forces the job into the BG_JOB_STATE_ERROR state when an error occurs.
If the retry period value exceeds the JobInactivityTimeout Group Policy setting (90-day default), BITS cancels the job after the JobInactivityTimeout Group Policy setting is exceeded.
The default is 1,209,600 seconds (14 days).
| Type: | Int32 |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-SecurityFlags
Specifies security flags for the HTTP request.
The flags you can set, from the least significant bit, are the following bits:
- 1: Enable CRL Check.
- 2: Ignore incorrect common names in the server certificate.
- 3: Ignore incorrect dates in the server certificate.
- 4: Ignore incorrect certification authorities in the server certificate.
- 5: Ignore incorrect usage of the server certificate.
- 12: Allow redirection from HTTPS to HTTP.
Use bits 9 through 11 to implement your redirection policy:
- 0,0,0: Redirects are automatically allowed.
- 0,0,1: Remote name is updated if a redirect occurs. -0,1,0: BITS fails the job if a redirect occurs.
| Type: | SecurityFlagValue |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Source
Specifies the source location and the names of the files that you want to transfer. The source file names are paired with the corresponding destination file names. For example, the first file name specified in the Source parameter corresponds to the first file name in the Destination parameter, and the second file name in the Source parameter corresponds to the second file name in the Destination parameter. The Source and Destination parameters must have the same number of elements; otherwise, the command produces an error. You can use standard wildcard characters such as the asterisk (*) and the question mark (?). Or, you can use a range operator such as "[a-r]".
| Type: | String[] |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-Suspended
Indicates that the cmdlet suspends the BITS transfer job. If the Suspended parameter is not specified, the job automatically begins the transfer job. If the Suspended parameter is specified, the command prompt returns immediately after the BITS transfer job is created. You can use the Resume-BitsTransfer cmdlet to start the transfer job.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-TransferPolicy
Specifies the network cost states in which the transfer is allowed to be scheduled. The current cost state of the network is a bitmask that indicates the kinds of charges that would be incurred if a transfer was scheduled at this time. This cost state represents a bitmask; if the bit corresponding to the current network cost state is set, the transfer can be scheduled. If the bit corresponding to the current network cost state is not set, the transfer is ignored for scheduling purposes. You can submit any of the named values listed here, or add them together to provide a custom value.
The acceptable values for this parameter are:
Unrestricted (or unknown) : 0x00000001 : the cost state for this network is not known.
Capped : 0x00000002 : the cost state for this network is a capped plan, or a plan that has a data usage limit.
BelowCap : 0x00000004 : the cost state for this network is below the data plan cap.
NearCap : 0x00000008 : the cost state for this network is near the data plan cap.
OverCapCharged : 0x00000010 : the cost state for this network is above the data plan cap, and such usage is charged.
OverCapThrottled : 0x00000020 : the cost state for this network is above the data plan cap, and such usage is throttled.
UsageBased : 0x00000040 : the cost state for this network is charged based on usage.
Roaming : 0x00000080 : the cost state for this network incurs roaming charges. The cost state also includes one option (IgnoreCongestion) and a set of standard policies (Uncosted, Standard, NoSurcharge, NotRoaming, and Always) which are combinations of the discrete bit values.
IgnoreCongestion : 0x80000000 : the job can be scheduled even if the network provider reports that the network is congested.
PolicyUnrestricted : 0x80000021 : the set of cost states that do not consume the quota of a capped plan, or incur extra charges.
Standard : 0x80000067 : a set of cost states suitable for moderate-priority transfers.
NoSurcharge : 0x8000006f : the set of cost states that incur no surcharge for use.
NotRoaming : 0x8000007f : the set of cost states that exclude the roaming state.
Always : 0x800000ff : the set of all cost states.
The cost state also includes one option (IgnoreCongestion) and a set of standard policies (Always, NotRoaming, NoSurcharge, Standard, and Uncosted) which are combinations of the discrete bit values.
| Type: | CostStates |
| Accepted values: | None, Unrestricted, Capped, BelowCap, NearCap, OverCapCharged, OverCapThrottled, UsageBased, Roaming, IgnoreCongestion, PolicyUnrestricted, Standard, NoSurcharge, NotRoaming, Always |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |

-TransferType
Specifies the BITS transfer job type. The acceptable values for this parameter are:
Download (the default): Specifies that the transfer job downloads files to the client computer.
Upload: Specifies that the transfer job uploads a file to the server.
UploadReply: Specifies that the transfer job uploads a file to the server and receives a reply file from the server.
| Type: | String |
| Accepted values: | Download, Upload, UploadReply |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-UseStoredCredential
Specifies that credentials stored in the Windows Credential Manager should be used for authentication when required for the specified target server type. If this parameter is not specified and a server requires authentication, then explicit credentials must be included by using the Credential or ProxyCredential parameters. This parameter is a flag parameter whose values can be added together to create the desired behavior.
The acceptable values for this parameter are:
None: Use only credentials provided by the Credential or ProxyCredential parameters. This is the default behavior if the parameter is not specified.
Proxy: Credentials stored in the Windows Credential Manager are used for authentication for any proxy server that requires authentication. If no credentials in the Windows Credential Manager match the proxy server needing authentication, then you must specify credentials by using the ProxyCredential parameter.
Server: This value is not supported and generates an error if specified.
| Type: | AuthenticationTargetValue |
| Accepted values: | None, Server, Proxy |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |

This cmdlet does not accept an input.
Outputs
Microsoft.BackgroundIntelligentTransfer.Management.BitsJob
When called with the Asynchronous parameter, this cmdlet passes the BitsJob object that is associated with the new BITS transfer job as output. Otherwise, no output is generated.
Notes
You can cancel a transfer job that is running in synchronous mode by pressing CTRL+C.
If the BITS service is stopped during a synchronous file transfer job, then file transfer job will fail with an error and the file transfer job will not get removed from the BitsTransfer queue. You can view the file transfer job that remains in the BitsTransfer queue through the Get-BitsTransfer cmdlet. The file transfer job that remains in the BitsTransfer queue can be removed using the Remove-BitsTransfer cmdlet. Once the BITS service is restarted, the file transfer job will recover and resume the file transfer job, unless the file transfer job has been removed in the interim.
