Get-DfsrBacklog

Get-DfsrBacklog

Retrieves the list of pending file updates between two DFS Replication partners.

Syntax

Parameter Set: Default
Get-DfsrBacklog [[-GroupName] <String[]> ] [[-FolderName] <String[]> ] [-SourceComputerName] <String> [-DestinationComputerName] <String> [ <CommonParameters>]




Detailed Description

The Get-DfrsBacklog cmdlet retrieves pending updates between two computers that participate in DFS Replication.

Updates can be new, modified, or deleted files and folders. The maximum number of files that this command displays is 100. The Verbose parameter displays a count of all backlogged updates. Any files or folders listed in the DFS Replication backlog have not yet replicated from the source computer to the destination computer. This is not necessarily an indication of problems. A backlog indicates latency, and a backlog may be expected in your environment, depending on configuration, rate of change, network, and other factors.

Parameters

-DestinationComputerName<String>

Specifies the name of the receiving computer. A destination computer is also called an inbound or downstream computer. If you do not specify this parameter, the cmdlet uses the local computer.


Aliases

ReceivingMember,RMem

Required?

true

Position?

4

Default Value

[local computer]

Accept Pipeline Input?

True (ByPropertyName)

Accept Wildcard Characters?

false

-FolderName<String[]>

Specifies an array of names of replicated folders. If you do not specify this parameter, the cmdlet queries for all participating replicated folders. You can specify multiple folders, separated by commas, as well as wildcard characters (*).

2

Default Value

none

Accept Pipeline Input?

True (ByPropertyName)

false

-GroupName<String[]>

Specifies an array of names of replication groups. If you do not specify this parameter, the cmdlet queries for all participating replications groups. You can specify multiple groups, separated by commas, as well as wildcard characters (*).


Aliases

Required?

false

Position?

1

Default Value

none

Accept Pipeline Input?

True (ByValue, ByPropertyName)

Accept Wildcard Characters?

false

-SourceComputerName<String>

Specifies the name of the sending computer. A source computer is also called an outbound or upstream computer.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (http://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

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

  • Microsoft.DistributedFileSystemReplication.DfsReplicationGroup, Microsoft.DistributedFileSystemReplication.DfsReplicatedFolder, string computerName

Outputs

The output type is the type of the objects that the cmdlet emits.

  • Microsoft.DistributedFileSystemReplication.DfsrIdRecord

Examples

Example 12: Retrieve unreplicated changes between upstream and downstream computers1

This command retrieves the first 100 unreplicated changes between the downstream computer SRV1 and the upstream computer SRV02 for the replication group RG01 and the replicated folder RF1. The command also formats the output into a table that contains only the file paths and modification dates on the upstream server.


PS C:\> Get-DfsrBacklog -DestinationComputerName SRV1 -SourceComputerName SRV02 -GroupName RG01 -FolderName RF1 | format-table fullpathname,updatetime

Example 23: Retrieve unreplicated changes count to display2

This command retrieves the total count of unreplicated changes between the downstream computer SRV02 and the upstream computer SRV01 for the replication group RG01 and the replicated folder RF01. The command displays this output in the verbose stream.


PS C:\> Get-DfsrBacklog -GroupName "RG01" -FolderName "RF01" -SourceComputerName "SRV01" -DestinationComputerName "SRV02" –Verbose

Example 34: Retrieve unreplicated changes count to a string object3

This command retrieves the total count of unreplicated changes between the downstream computer SRV02 and the upstream computer SRV01 for the replication group RG01 and the replicated folder RF01. The command converts the verbose stream data into a text string containing only the count, for later manipulation.


PS C:\> (Get-DfsrBacklog -GroupName "RG01" -FolderName "RF01" -SourceComputerName "SRV01" -DestinationComputerName "SRV02" -Verbose 4>&1).Message.Split(':')[2]

Example 45: Retrieve unreplicated changes count to a file4

This command retrieves the total count of unreplicated changes between the downstream computer SRV02 and the upstream computer SRV01 for the replication group RG01 and the replicated folder RF01. The command converts the verbose stream data into a text string containing only the count, for later manipulation.


PS C:\> Get-DfsrBacklog -GroupName "RG01" -FolderName "RF01" -SourceComputerName "SRV01" -DestinationComputerName "SRV02" -Verbose 4> verbose.txt > nullPS C:\> Get-Content .\verbose.txt
