Robust File and Folder Copy.

By default Robocopy will only copy a file if the source and destination have different time stamps or different file sizes.

 

Syntax

ROBOCOPY Source_folder Destination_folder [files_to_copy] [options]

 

Key

file(s)_to_copy : A list of files or a wildcard.

(defaults to copying *.*)

 

  Source options

/S : Copy Subfolders.

/E : Copy Subfolders, including Empty Subfolders.

/COPY:copyflag[s] : What to COPY (default is /COPY:DAT)

(copyflags : D=Data, A=Attributes, T=Timestamps

S=Security=NTFS ACLs, O=Owner info, U=aUditing info).

/SEC : Copy files with SECurity (equivalent to /COPY:DATS).

/DCOPY:T : Copy Directory Timestamps. ##

/COPYALL : Copy ALL file info (equivalent to /COPY:DATSOU).

/NOCOPY : Copy NO file info (useful with /PURGE).

 

/A : Copy only files with the Archive attribute set.

/M : like /A, but remove Archive attribute from source files.

/LEV:n : Only copy the top n LEVels of the source tree.

 

/MAXAGE:n : MAXimum file AGE – exclude files older than n days/date.

/MINAGE:n : MINimum file AGE – exclude files newer than n days/date.

(If n < 1900 then n = no of days, else n = YYYYMMDD date).

 

/FFT : Assume FAT File Times (2-second date/time granularity).

/256 : Turn off very long path (> 256 characters) support.

 

Copy options

/L : List only – don’t copy, timestamp or delete any files.

/MOV : MOVe files (delete from source after copying).

/MOVE : Move files and dirs (delete from source after copying).

 

/Z : Copy files in restartable mode (survive network glitch).

/B : Copy files in Backup mode.

/ZB : Use restartable mode; if access denied use Backup mode.

/IPG:n : Inter-Packet Gap (ms), to free bandwidth on slow lines.

 

/R:n : Number of Retries on failed copies – default is 1 million.

/W:n : Wait time between retries – default is 30 seconds.

/REG : Save /R:n and /W:n in the Registry as default settings.

Destination options

 

/A+:[RASHCNET] : Set file Attribute(s) on destination files + add.

/A-:[RASHCNET] : UnSet file Attribute(s) on destination files – remove.

/FAT: Create destination files using 8.3 FAT file names only.

 

/CREATE: CREATE directory tree structure + zero-length files only.

/DST: Compensate for one-hour DST time differences ##

/PURGE: Delete dest files/folders that no longer exist in source.

/MIR: MIRror a directory tree – equivalent to /PURGE plus all subfolders (/E)

 

Logging options

Advanced options you’ll probably never use

/EFSRAW : Copy any encrypted files using EFS RAW mode. ##

/MT[:n] : Multithreaded copying, n = no. of threads to use (1-128) ###

default = 8 threads, not compatible with /IPG and /EFSRAW

The use of /LOG is recommended for better performance.

 

/SECFIX : FIX file SECurity on all files, even skipped files.

/TIMFIX : FIX file TIMes on all files, even skipped files.

 

/XO : eXclude Older – if destination file exists and is the same date or newer than the source – don’t bother to overwrite it.

/XC | /XN : eXclude Changed | Newer files

/XL : eXclude “Lonely” files and dirs (present in source but not destination)

This will prevent any new files being added to the destination.

This will prevent any deletions from the destination. (this is the default)

 

/XF file [file]… : eXclude Files matching given names/paths/wildcards.

/XD dirs [dirs]… : eXclude Directories matching given names/paths.

XF and XD can be used in combination  e.g.

ROBOCOPY c:\source d:\dest /XF *.doc *.xls /XD c:\unwanted /S

/X : Report all eXtra files, not just those selected & copied.

/V : Produce Verbose output log, showing skipped files.

/ETA : Show Estimated Time of Arrival of copied files.

## = New Option in Vista (XP027) all other options are valid for the XP version of Robocopy (XP010)

### = New Option in Windows 7 and Windows 2008 R2

 

Robocopy EXIT CODES

 

File Attributes [RASHCNETO]

 

R – Read only

A – Archive

S – System

H – Hidden

C – Compressed

N – Not content indexed

E – Encrypted

T – Temporary

O – Offline

If either the source or desination are a “quoted long foldername” do not include a trailing backslash as this will be treated as an escape character, i.e. “C:\some path\” will fail but “C:\some path\\” or “C:\some path\.” or “C:\some path” will work.

 

By copying only the files that have changed, robocopy can be used to backup very large volumes.

 

ROBOCOPY will accept UNC pathnames including UNC pathnames over 256 characters long.

 

/REG Writes to the registry at HKCU\Software\Microsoft\ResKit\Robocopy

 

/XX (exclude extra) If used in conjunction with /Purge or /Mir, this switch will take precedence and prevent any files being deleted from the destination.

 

To limit the network bandwidth used by robocopy, specify the Inter-Packet Gap parameter /IPG:n

This will send packets of 64 KB each followed by a delay of n Milliseconds.

 

Open Files

 

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.

 

Permissions

 

All versions of Robocopy will copy security information (ACLs) for directories, version XP010 will not copy file security changes unless the file itself has also changed, this greatly improves performance.

 

/B (backup mode) will allow Robocopy to override file and folder permission settings (ACLs).

 

ERROR 5 (0x00000005) Changing File Attributes … Access is denied

This 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.

 

To run ROBOCOPY under a non-administrator account will require backup files privilege, to copy security information auditing privilege is also required, plus of course you need at least read access to the files and folders.

 

Availability

 

Robocopy is a standard command in Windows 7 and above. The Windows Server 2003 Resource Kit Tools 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).

 

Robocopy ‘Jobs’ and the ‘MOnitor source’ option provide an alternative to setting up a Scheduled Task to run a batchfile with a RoboCopy command.

 

Examples:

 

Copy files from one server to another including subfolders (/S)

If 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.

 

ROBOCOPY \\Server1\reports \\Server2\backup *.doc /S

List files over 32 MBytes in size:

 

ROBOCOPY C:\work /MAX:33554432 /L

Move files over 14 days old: (note the MOVE option will fail if any files are open and locked.)

 

ROBOCOPY C:\work C:\destination /move /minage:14

Backup a Server:

The 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.)

 

@ECHO OFF

SETLOCAL

 

SET _source=\\FileServ1\e$\users

 

SET _dest=\\FileServ2\e$\BackupUsers

 

SET _what=/COPYALL /B /SEC /MIR

:: /COPYALL :: COPY ALL file info

:: /B :: copy files in Backup mode.

:: /SEC :: copy files with SECurity

:: /MIR :: MIRror a directory tree

 

SET _options=/R:0 /W:0 /LOG:MyLogfile.txt /NFL /NDL

:: /R:n :: number of Retries

:: /W:n :: Wait time between retries

:: /LOG :: Output log file

:: /NFL :: No file logging

:: /NDL :: No dir logging

 

ROBOCOPY %_source% %_dest% %_what% %_options%

 

Run two robocopy jobs at the same time with START /Min

 

Start /Min “Job one” Robocopy \\FileServA\C$\Database1 \\FileServeBackupA\c$\Backups

Start /Min “Job two” Robocopy \\FileServB\C$\Database2 \\FileServeBackupB\c$\Backups

Here is a quick reference you can use to determine which tools to use to help locate and resolve problems with your AD network.

Q: User unable to access network resources?

Is the network functioning at all? Can you view a list of networked systems or even access resources on other computers? If not, you have network connectivity problems. The troubleshooting tools you should start with include: Event Viewer, Ping, IPCONFIG, NLTEST, NetDiag and Network Monitor.

Q: User unable to locate resources by name?

Is name resolution functioning? Can you resolve NetBIOS or domain names into IP addresses using Windows Explorer or PING? If not, you have name resolution service problems. The troubleshooting tools you should start with include: Event Viewer, NSLOOKUP, NBTSTAT and DNSCMD.

Q: User unable to log in and obtain its roaming profile?

If not, your DC is having problems. The troubleshooting tools you should start with include: Event Viewer, DCDiag, DSASTAT and NTDSUTIL.

Q: User is unable to authenticate?

Can any client log on locally or remotely? If not, your DC is not authenticating properly. The troubleshooting tools you should start with include: Event Viewer and NetSetup.

Q: User unable to access resources as expected?

Can you access objects that you should be granted access to, and are you restricted from objects that you should not have access to? If not, then either the ACLs or DC is not functioning properly. The troubleshooting tools you should start with include: Event Viewer, DSACLS, NETDOM and SDCHECK.

User logon problems are sometimes hard to troubleshoot. Have you checked the Application log on the machine in question? There might be (most likely) some errors in there from source Userenv (ID’s 1053, 1054).
Turning on Userenv debug logging will also help in troubleshooting user logon problems. You can do this by adding a Registry key:

– Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
– Value: UserEnvDebugLevel
– Value Type: REG_DWORD
– Value Data: 10002 (Hex)

The log will be located in: %systemroot%\debug\usermode\userenv.log.

In the log you will exactly see what happens during logon at what time. If you see a large difference between times you’ll know what part of the logon process is causing the long delay.

In this section, we’ll discuss the registry keys that are used for power management. You may edit any of them using one of the registry editors.

Note Changing registry entries responsible for power management won’t have an immediate effect. Windows only reads settings from the registry when you log on, when you click OK in Control Panel, or when a Powerprof.dll function is called on to read the registry.

The registry keys used for power management are listed below.

  • HKCU\AppEvents\EventLabels\LowBatteryAlarm – descriptive name of a low battery-power-alarm event
  • HKCU\AppEvents\EventLabels\CriticalBatteryAlarm – descriptive name of a critical battery-power-alarm event
  • HKCU\AppEvents\Schemes\Apps\PowerCfg\LowBatteryAlarm\.Current, HKCU\AppEvents\Schemes\Apps\PowerCfg\LowBatteryAlarm\.Default, HKCU\AppEvents\Schemes\Apps\PowerCfg\CriticalBatteryAlarm\.Current, HKCU\AppEvents\Schemes\Apps\PowerCfg\CriticalBatteryAlarm\.Default – filenames of the WAV files that will play as a low and critical power-alarm events
  • HKCU\Control Panel\PowerCfg\CurrentPowerPolicy – index of current user and machine power policy
  • HKCU\Control Panel\PowerCfg\GlobalPowerPolicy\Policies – the user global power policy (binary encoded data)
  • HKCU\Control Panel\PowerCfg\PowerPolicies\n\Name – name of power scheme n, where n = 0, 1, 2, etc.
  • HKCU\Control Panel\PowerCfg\PowerPolicies\n\Description – descriptive string for power scheme n, where n = 0, 1, 2, etc.
  • HKCU\Control Panel\PowerCfg\PowerPolicies\n\Policies – user power policy n, where n = 0, 1, 2, etc. (binary encoded data)
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\LastID – index of the last power policy in the lists of user and machine power policies (for example, if there are six user power policies and six machine power policies in the registry, the value of this key is 5)
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\DiskSpinDownMax – the maximum disk spin-down time that Control Panel will allow the user to set
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\DiskSpinDownMin – the minimum disk spin-down time that Control Panel will allow the user to set
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\GlobalPowerPolicy\Policies – the machine global power policy (binary encoded data)
  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies\n\Policies – machine power policy n, where n = 0, 1, 2, etc. (binary encoded data)


Power management configuration in Windows 2000, Windows XP, and Windows Server 2003 is based on the concept of power schemes. A power scheme is a group of preset power options that are passed to the Power Policy Manager component of the operating system to control the machine’s power-management behavior.

Each power scheme consists of a global power-policy structure and a power-policy structure.

  • Global power-policy structures contain preset power options that are global across all power schemes.
  • Non-global power-policy structures contain power options that are unique to a particular power scheme.

These power-policy structures are further divided into machine structures and user structures.

  • Values in machine structures are stored in the HKEY_LOCAL_MACHINE registry key, and none of these values are exposed in the user interface. For example, you can’t set any of these values using the Power Options applet in the Control Panel.
  • Values in user structures are stored in the HKEY_CURRENT_USER registry key and some of these values are displayed in the user interface. Some of these parameters can be set using the Power Options applet in Control Panel.

The data structures defining power management policy are listed below:

  • GLOBAL_POWER_POLICY – used to manage global power policies. This structure contains the data common to all power schemes. This structure is a container for a GLOBAL_USER_POWER_POLICY structure and a GLOBAL_MACHINE_POWER_POLICY structure, which contains elements that are read from and written to the registry.
  • GLOBAL_MACHINE_POWER_POLICY – this structure is a part of the GLOBAL_POWER_POLICY structure. It contains the data common to all power schemes and users. The elements in this structure are read from and written to the HKLM key in the registry.
  • GLOBAL_USER_POWER_POLICY – this structure is a part of the GLOBAL_POWER_POLICY structure. It contains the data common to all power schemes for the user. The elements in this structure are read from and written to the HKCU key in the registry.
  • POWER_POLICY – used to manage non-global power policies. This structure contains the data unique for all power schemes. This structure is a container for the USER_POWER_POLICY and MACHINE_POWER_POLICY structures that contain the elements to be read from and written to the registry. There is one POWER_POLICY structure for each power scheme on a machine.
  • MACHINE_POWER_POLICY – this structure is a part of the POWER_POLICY structure. It contains the data unique to each power scheme, but common to all users. The elements in this structure are read from and written to the HKLM key in the registry.
  • USER_POWER_POLICY – this structure is a part of the POWER_POLICY structure. It contains the data unique to each user and power scheme. The elements in this structure are read from and written to the HKCU key in the registry.

Why Doesn’t Windows Remember My Folder View Settings?
If you’ve changed the view settings for a folder, but Windows “forgets” the settings when you open the folder again, or if Windows doesn’t seem to remember the size or position of your folder window when you reopen it, this could be caused by the default limitation on storing view settings data in the registry; by default Windows only remembers settings for a total of 200 local folders and 200 network folders.
To work around this problem, create a BagMRU Size DWORD value in both of the following registry keys, and then set the value data for both values to the number of folders that you want Windows to remember the settings for. For example, for Windows to remember the settings for 5000 local folders and 5000 network folders, set both values to 5000.
Here is how:
Follow these steps, and then quit Registry Editor:
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type BagMRU Size, and then press ENTER.
5. On the Edit menu, click Modify.
6. Type 5000, and then click OK.
AND:
1. Locate and then click the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam
2. On the Edit menu, point to New, and then click DWORD Value.
3. Type BagMRU Size, and then press ENTER.
4. On the Edit menu, click Modify.
5. Type 5000, and then click OK.
Note:
When you use roaming user profiles, registry information is copied to a server when you log off and copied to your local computer when you log on. Therefore, you may have performance issues if you increase the BagMRU Size values for roaming user profiles.

Thumbnail Cache

***************

[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced]

“DisableThumbnailCache”=dword:00000001

Windows XP has a neat feature for graphic and video files that creates a “thumbnail” of the image or first frame of the video and makes it into an oversized icon for the file. There are two ways that Explorer can do this, it can create them fresh each time you access the folder or it can load them from a thumbnail cache. The thumbnail caches on systems with a large number of image and video files can become staggeringly large. To disable the Thumbnail Cache, browse to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced and find the DWORD “DisableThumbnailCache”. You may need to create this key. A setting of 1 is recommended for systems where the number of graphic and video files is large, and a setting of 0 is recommended for systems not concerned about hard drive space, as loading the files from the cache is significantly quicker than creating them from scratch each time a folder is accessed.
