Powinieneś być w porządku, aby korzystać z rodzimego systemu Windows Robocopy polecenie zamiast XCOPY lub FC który jest sposób bardziej odporny aby ukończyć zadanie, tak jak to opisujesz, robisz to. Jest to prosta i jasna metoda wykorzystująca Natywny system Windows ROBOCOPY polecenia ze skryptu wsadowego lub wiersza poleceń. Możesz również sprawdzić plik dziennika w poszukiwaniu dokładnych plików, które były różne i zostały później skopiowane do miejsca docelowego.
Jeśli budujesz coś nowego, najlepiej użyć Robocopy zamiast XCOPY tak jak XCOPY uważam, że jest to przestarzałe polecenie, które ma zostać zastąpione przez Robocopy specjalnie dla Microsoft jako Windows Vista (i nowsze OS).
Skrypt Robocopy
(Widzieć Uwaga dotycząca skryptu poniżej dla opcji użytych w tym przykładzie, a także zmień ścieżki zmiennych sourcedir i targetdir tam, gdzie są one potrzebne. Pamiętaj, aby przetestować również z lokalizacji testowej, aby być dokładnym i potwierdzić się przed użyciem do celów produkcyjnych)
@ECHO ON
SETLOCAL
SET SourceDir=C:\SourcePath
SET TargetDir=C:\TargetPath
SET LogFile=C:\LogPath\Logfile.txt
ROBOCOPY "%SourcePath%" "%TargetDir%" *.* /PURGE /S /NP /R:5 /LOG+:%Log% /TS /FP
GOTO EOF
Uwaga dotycząca skryptu
Użyłem tych opcji w moim przykładzie, ale zobacz poniżej, jak zobaczyć wszystkie opcje, aby lepiej dopasować się do Twoich potrzeb.
/S :: copy Subdirectories, but not empty ones.
/PURGE :: delete dest files/dirs that no longer exist in source.
/NP :: No Progress - don't display % copied.
/R:n :: number of Retries on failed copies: default 1 million.
/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.
