ROBOCOPY.exe (XP Resource Kit<\/a>\/Standard Windows 7 command)<\/h1>\n

Robust File and Folder Copy.

## = New Option in Vista (XP027) all other options are valid for the XP version of Robocopy (XP010)
\n### = New Option in Windows 7 and Windows 2008 R2<\/p>\n
Robocopy EXIT CODES<\/a><\/p>\n
File Attributes <\/b>[RASHCNETO]<\/p>\n
 R \u2013 Read only \r\n A \u2013 Archive \r\n S \u2013 System \r\n H \u2013 Hidden\r\n C \u2013 Compressed \r\n N \u2013 Not content indexed\r\n E \u2013 Encrypted \r\n T \u2013 Temporary\r\n O - Offline<\/pre>\n
If either the source or desination are a “quoted long foldername” do not include a trailing backslash<\/b> as this will be treated as an escape character, i.e. “C:\\some path\\”<\/span> will fail but “C:\\some path\\\\”<\/span> or “C:\\some path\\.”<\/span> or “C:\\some path”<\/span> will work.<\/p>\n
By copying only the files that have changed, robocopy can be used to backup very large volumes.<\/p>\n
ROBOCOPY will accept UNC pathnames including UNC pathnames over 256 characters long.<\/p>\n
\/REG<\/span> Writes to the registry at HKCU\\Software\\Microsoft\\ResKit\\Robocopy<\/span><\/p>\n
\/XX<\/span> (exclude extra) If used in conjunction with \/Purge or \/Mir, this switch will take precedence and prevent any files being deleted from the destination.<\/p>\n
To limit the network bandwidth used by robocopy, specify the Inter-Packet Gap parameter \/IPG:n<\/i> <\/span>
\nThis will send packets of 64 KB each followed by a delay of n<\/i> Milliseconds.<\/p>\n
Robocopy will fail to copy files that are locked by other users or applications, so limiting the number of retries with \/R:0 will speed up copying by skipping any in-use files. The Windows Volume Shadow Copy service is the only Windows subsystem that can copy open files. Robocopy does not use the Volume Shadow Copy service, but it can backup a volume shadow that has already been created with VSHADOW or DISKSHADOW<\/a>.<\/p>\n
All versions of Robocopy will copy security information (ACLs) for directories, version XP010 will not copy file security changes<\/a> unless the file itself has also changed, this greatly improves performance.<\/p>\n
\/B<\/span> (backup mode) will allow Robocopy to override file and folder permission settings (ACLs).<\/p>\n
ERROR 5 (0x00000005) Changing File Attributes … Access is denied<\/span>
\nThis error usually means that File\/Folder permissions or Share permissions on either the source or the destination are preventing the copy, either change the permissions or run the command in backup mode with \/B<\/span>.<\/p>\n
To run ROBOCOPY under a non-administrator account will require backup files<\/a><\/i> privilege<\/a>, to copy security information auditing<\/a><\/i> privilege<\/a> is also required, plus of course you need at least read <\/i>access to the files and folders.<\/p>\n
<\/a>Examples:<\/h2>\n
Simple copy of all files from one folder to another:<\/p>\n
ROBOCOPY \\\\Server1\\reports \\\\Server2\\backup<\/pre>\n
Copy files including subfolders (even empty ones \/E<\/span>)
\nIf this command is run repeatedly it will skip any files already in the destination, however it is not a true mirror as any files deleted from the source will remain in the destination.<\/p>\n
ROBOCOPY \\\\Server1\\reports \\\\Server2\\backup *.* \/E<\/pre>\n
List files over 32 MBytes in size:<\/p>\n
ROBOCOPY C:\\work \/MAX:33554432 \/L<\/pre>\n
Move files over 14 days old: (note the MOVE option will fail if any files are open and locked.)<\/p>\n
ROBOCOPY C:\\work C:\\destination \/move \/minage:14<\/pre>\n
Backup a Server:
\nThe script below copies data from FileServ1 to FileServ2, the destination holds a full mirror along with file security info. When run regularly to synchronize the source and destination, robocopy will only copy those files that have changed (change in time stamp or size.)<\/p>\n

Availability<\/h2>\n
Robocopy is a standard command in Windows 7 and above. The  Windows Server 2003 Resource Kit Tools<\/a> include Robocopy XP010, which can be run on NT 4\/ Windows 2000. Robocopy does not run on Windows 95, or NT 3.5. (RoboCopy is a Unicode application).<\/p>\n
Robocopy ‘Jobs’ and the ‘MOnitor source’ option provide an alternative to setting up a Scheduled Task<\/a> to run a batchfile with a RoboCopy command.<\/p>\n
Bugs<\/h1>\n
The Windows 7 \/Server 2008 R2 version of RoboCopy will incorrectly skip some files if the filenames contain East Asian characters, for example Japanese characters. A hotfix is available to correct this KB2680906<\/a><\/p>\n
Version XP026 returns a success errorlevel even when it fails.<\/p>\n
