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 [file(s)_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 : What to COPY (default is /COPY:DAT).                      (copyflags : D=Data, A=Attributes, T=Timestamps).                      (S=Security=NTFS ACLs, O=Owner info, U=aUditing info).          /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 n = no of days, else n = YYYYMMDD date).

              /FFT : assume FAT File Times (2-second 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.

              /TBD : wait for sharenames To Be Defined (retry error 67).

   Destination options

  /A+:[R][A][S][H] : set file Attributes on destination files - add.  /A-:[R][A][S][H] : set file Attributes on destination files - remove.              /FAT : create destination files using 8.3 FAT file names only.

           /CREATE : CREATE directory tree structure + zero-length files only.            /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                /L : List only - don't copy, timestamp or delete any files.               /NP : No Progress - don't display % copied.         /LOG:file : output status to LOG file (overwrite existing log).        /LOG+:file : output status to LOG file (append to existing log).

               /TS : include source file Time Stamps in the output.               /FP : include Full Pathname of files in the output.               /NS : No Size - don't log file sizes.               /NC : No Class - don't log file classes.              /NFL : No File List - don't log file names.              /NDL : No Directory List - don't log directory names.              /TEE : output to console window, as well as the log file.              /NJH : No Job Header.              /NJS : No Job Summary.

Repeated Copy Options            /MON:n : MONitor source; run again when more than n changes seen.            /MOT:m : MOnitor source; run again in m minutes Time, if changed.

     /RH:hhmm-hhmm : Run Hours - times when new copies may be started.               /PF : check run hours on a Per File (not per pass) basis.

Job Options      /JOB:jobname : take parameters from the named JOB file.     /SAVE:jobname : SAVE parameters to the named job file             /QUIT : QUIT after processing command line (to view parameters).              /NOSD : NO Source Directory is specified.             /NODD : NO Destination Directory is specified.               /IF : Include the following Files.

Advanced options you'll probably never use               /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         /XX | /XL : eXclude eXtra | Lonely files and dirs.                      An "extra" file is present in destination but not source,                      excluding extras will delete from destination.                      A "lonely" file is present in source but not destination                     excluding lonely will prevent any new files being added to the destination.               /IS : Overwrite files even if they are already the same.

/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

            /MAX:n : MAXimum file size - exclude files bigger than n bytes.            /MIN:n : MINimum file size - exclude files smaller than n bytes.

               /IT : Include Tweaked files.               /XJ : eXclude Junction points. (normally included by default).         /MAXLAD:n : MAXimum Last Access Date - exclude files unused since n.         /MINLAD:n : MINimum Last Access Date - exclude files used since n.                     (If n
  /XA:[R][A][S][H] : eXclude files with any of the given Attributes  /IA:[R][A][S][H] : Include files with any of the given Attributes

                /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.Syntax on this page is for the XP and .Net Version of Robocopy (XP010)
The NT 4 and Windows 2000 resource kits include
Robocopy 1.95
but I recommend you
download the XP version
which fixes a number of bugs - it runs fine on NT/2K.
Robocopy does not run on Windows 95, or NT 3.5. (RoboCopy is a Unicode application).
ROBOCOPY will accept UNC pathnames.
Examples:
:: Copy files from one server to another
ROBOCOPY \Server1eports \Server2ackup *.doc /S /NP
:: List all files over 32 MBytes in size
ROBOCOPY C:work /MAX:33554432 /L
:: Move files over 14 days old
ROBOCOPY C:work C:destination /move /minage:14
:: Note the MOVE option will fail if any files are open and locked.
:: The script below copies data from FileServ1 to FileServ2, the destination holds a full mirror (all files), but when run repeatedly will only copy changed files. (Changed meaning different time stamps or different sizes)
@ECHO OFF
SETLOCAL
SET _source=\FileServ1e$users
SET _dest=\FileServ2e$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
