Robocopy and a Few Examples

 
Robocopy (Robust File Copy) is a command-line file copy utility that comes with Windows Vista / Windows 2008 or newer. Until Vista, Robocopy was a part of  Windows Resource Kit Tools as a free download (http://www.microsoft.com/downloads/details.aspx?FamilyID=9D467A69-57FF-4AE7-96EE-B18C4790CFFD&displaylang=en ). Unlike normal copy commands, Robocopy is designed for reliable copy or mirroring while maintaining the permissions, attributes, owner information, timestamps and properties of the objects copied.

A few of my customers were complaining that there is not enough documentation on robocopy usage and examples. I am trying to document some of the common scenarios where robocopy can be useful.


Robocopy Syntax
ROBOCOPY <source> <destination> [file…] [options]

<source>        Source Directory (local or network path)
<destination>  Destination Directory (local or network path) and
[file…]              Specifies the file or files to be copied. You can use wildcard characters (* or ?), if you want. If the File parameter is not specified, *.* is used as the default value.
 
 **Skip to the end of this document for more information on Robocopy Options and Switches .

Examples of Microsoft's Robocopy Syntax


#1

To copy contents of C:\UserFolder to C:\FolderBackup:
         Robocopy C:\UserFolder C:\FolderBackup
This is the simplest usage for Robocopy

#2
To copy all contents including empty directories of SourceFolder to DestinationFolder:
Robocopy C:\SourceDir C:\DestDir /E

#3
List only files larger than 32 MBytes(33553332 bytes) in size.
            Robocopy.exe c:\sourceFolder d:\targetfolder /min:33553332 /l
List only files less than 32 MBytes(33553332 bytes) in size.
          Robocopy.exe c:\sourceFolder d:\targetfolder /max:33553332 /l
Note: /l - will list files matching the criteria. if /l is omitted, files matching the criteria will be copied to the taget location

#4
Move files over 14 days old (note the MOVE option will fail if any files are open and locked).
ROBOCOPY C:\SourceFoldern D:\DestinationFolder /move /minage:14
Similarly you could use the below switches
/maxage: <N>     Specifies the maximum file age (to exclude files older than N days or date).
/minage: <N>      Specifies the minimum file age (exclude files newer than N days or date).
/maxlad: <N>      Specifies the maximum last access date (excludes files unused since N).
/minlad: <N>       Specifies the minimum last access date (excludes files used since N) If N is less than 1900, N specifies the number of days. Otherwise, N specifies a date in the format YYYYMMDD

#5
/MIR is an option to ROBOCOPY where you mirror a directory tree with all the subfolders including the empty directories and you purge files and folders on the destination server that no longer exists in source.
ROBOCOPY \\sourceserver\share \\destinationserver\share /MIR
Or
ROBOCOPY source-drive:\DIR destination-drive:\DIR /MIR

#6
The following command will mirror the directories using Robocopy:
Robocopy \\SourceServer\Share \\DestinationServer\Share /MIR /FFT /Z /XA:H /W:5
 /MIR specifies that Robocopy should mirror the source directory and the destination directory. Note that this will delete files at the destination if they were deleted at the source.
/FFT uses fat file timing instead of NTFS. This means the granularity is a bit less precise. For across-network share operations this seems to be much more reliable - just don't rely on the file timings to be completely precise to the second.
/Z
ensures Robocopy can resume the transfer of a large file in mid-file instead of restarting.
/XA:H makes Robocopy ignore hidden files, usually these will be system files that we're not interested in.
/W:5 reduces the wait time between failures to 5 seconds instead of the 30 second default.


#7
Use Robocopy to copy all changes to files in a directory called c:\data to a directory that contains the date, like data_20091124.  Create a batch file as follows.
@echo off
set day=%date:~0,2%
set month=%date:~3,2%
set year=%date:~6,4%
Robocopy "c:\data" "c:\backup\data\%day%-%month%-%year%\" /MAXAGE:1

#8
To mirror the directory "C:\directory" to "\\server2\directory" excluding \\server2\directory\dir2" from being deleted (since it isn't present in C:\directory) use the following command:
Robocopy "C:\Folder" "\\Machine2\Folder" /MIR /XD  \\server2\ directory\dir2"
Robocopy can be setup as a simply Scheduled Task that runs daily, hourly, weekly etc. Note that Robocopy also contains a switch that will make Robocopy monitor the source for changes and invoke synchronization each time a configurable number of changes has been made. This may work in your scenario, but be aware that Robocopy will not just copy the changes, it will scan the complete directory structure just like a normal mirroring procedure. If there are a lot of files & directories, this may hamper performance.

#9
You have copied the contents from source to destination but now you made changes to the Security permissions at source. You wanted to copy only the permission changes and not data.

ROBOCOPY <Source> <Target> /E /Copy:S /IS /IT

Copy option have the following flags to use:
D     Data
A     Attributes
T     Time stamps
S     NTFS access control list (ACL)
O    Owner information
U     Auditing information
The default value for CopyFlags is DAT (data, attributes, and time stamps).
/IS - Includes the same files.
/IT - Includes "tweaked" files.

Sidenote: ROBOCOPY  c:\sourcefolder d:\targetfolder /zb /sec /e /nocopy may give you similar results but useful ONLY when more permissions are added. it will not consider or update the target for permissions removed at the source.


Robocopy, short for Robust File Copy, is a command-line directory replication and file copy command utility that was first made available as feature in Windows Vista and Windows Server 2008, although it has been available as part of Windows Resources Kit. In Windows 7 and Windows Server 2008, Robocopy utility is further enhanced with ability to multi-threaded copy operation feature.

Multi-threaded support allows Robocopy to open multiple
threads simultaneously, allowing many files to be copied in parallel. With multi-threaded copying, total time required to complete the operation will be drastically reduced and cut, when comparing with with typical copying one file at time in serial sequential order.

As Robocopy is
generally a command-line only utility (although a GUI add-on is available for Robocopy), the new multi-threaded operation capability has to be called via a new switch supported by Robocopy. The new multi-threaded copy feature can be enabled and turned on with the following parameter:
/MT[:n]
Where n will instruct Robocopy to do multi-threaded copies with n threads (default 8). The value of n must be at least 1 and not greater than 128 (between 1 to 128), with 1 as single thread. In fact, Robocopy will copy files and folders in multi-threaded operation by default, with 8 threads in one go. Note that /MT[:n] switch is not compatible with the /IPG and /EFSRAW operations.

For example,
Robocopy C:\Folder1 C:\Folder2 /MT:32

#10
To copy a directory tree along with the source timestamps for folders
Robocopy C:\Folder1 C:\Folder2 /MIR /dcopy:T

#11
To copy a directory using /IPG to limit bandwidth usage. General rule of thumb /IPG:750 will use roughly 1Mbps.

Robocopy /ipg:750 /z /r:3 /w:3 /tee /LOG+:c:\robolog.txt //server1/share //server2/share

How to delete a Team Project in TFS 2010 through Command Line



Hi,
In this Post i will explain you about how to delete Team project in TFS through command line Utility
.
TFS Delete Project Command line tool. You can find this in Drive:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE on any client computer that runs Team Explorer.
To use the TFSDeleteProject command, you must be a member of the Team Foundation Administrators security group or the Project Administrators security group.
Also please note that TFSDeleteProject permanently destroys the team project, after which it cannot be recovered. You should backup all important project data before using TFSDeleteProject (if needed).

Syntex
 
TFSDeleteproject [/q] [/force] [/excludewss] /collection:URLTeamProjectName

Below are parameters that need to be specified as per the requirements:
Option
Description
/q
Optional. Use the quiet mode. Do not prompt the user for confirmation.
/force
Optional. Specifies that the deletion process should continue even if some components cannot be deleted.
/excludewss
Optional. Specifies to not delete the SharePoint site that is associated with the team project. Specify this option to maintain the existing site so that other team projects can continue using it.
/collection:URL
Required. Specifies the URI of the team project collection. You must use the following format for the URI: http://ServerName:Port/VirtualDirectoryName/CollectionName
If you do not specify a virtual directory, you must use the following format for the URI:
http://ServerName:Port/CollectionName.
TeamProjectName
Required. The name of the project. If the name includes spaces, enclose it in quotations marks.
 Now, I want to delete the OMG Team Project from my TFS Server.



I am running TFS delete project command line tool using VS command prompt. It will also prompt for confirmation.




Done. Now, as you can see below Team Project OMG is completely deleted from my TFS Server.
