Tip : robocopy.exe (Robust File Copy for Windows)

Post by jataz2 » 27/03/2019 5:06 pm

เป็นคำสั่ง dos การใช้งานหลักๆคือ เอาไว้ move ไฟล์ จากที่นึงไปอีกที่นึง มี optional หลายอันที่ตรงกับที่ต้องการคือ copy เอาเฉพาะไฟล์ที่ใหม่กว่า หรือที่ยังไม่มีที่ destination dir


robocopy.exe D:\document\ \\fileserver1\TEST_ROBOCOPY\ *.* /MAXAGE:20190101 /XO /E

คัดลอกทุกไฟล์และ sub directory ที่อยู่ใน path : D:\document\
ไปวางที่ \\fileserver1\TEST_ROBOCOPY\
เอาเฉพาะไฟล์ที่ใหม่กว่า หรือที่ยังไม่มีที่ destination dir

/XO :: eXclude Older files.
/E :: copy subdirectories, including Empty ones.
/MAXAGE: ถ้าไฟล์อายุเก่ากว่าวันที่นี้ไม่เอา

งานบางอย่างไม่ต้องการ ทำในทันทีทันใด ก็ตั้งรันเป็น Shcedule task ตั้งวันรันละครั้งได้ หรือรันทุก 5 นาที เพื่อ sync ไฟล์ทั้ง 2 โฟลเดอร์ให้มีเท่ากัน


ดู option เพิ่มเติมก็พิมพ์ robocopy.exe /?

::
:: Copy options :

/SEC :: copy files with SECurity (equivalent to /COPY:DATS).
/COPYALL :: COPY ALL file info (equivalent to /COPY:DATSOU).
/NOCOPY :: COPY NO file info (useful with /PURGE).
/SECFIX :: FIX file SECurity on all files, even skipped files.
/TIMFIX :: FIX file TIMes on all files, even skipped files.

/PURGE :: delete dest files/dirs that no longer exist in source.
/MIR :: MIRror a directory tree (equivalent to /E plus /PURGE).

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

/A+:[RASHCNET] :: add the given Attributes to copied files.
/A-:[RASHCNET] :: remove the given Attributes from copied files.

/CREATE :: CREATE directory tree and zero-length files only.
/FAT :: create destination files using 8.3 FAT file names only.
/256 :: turn off very long path (> 256 characters) support.

/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.

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

/SL :: copy symbolic links versus the target.

/MT[:n] :: Do multi-threaded copies with n threads (default 8).
n must be at least 1 and not greater than 128.
This option is incompatible with the /IPG and /EFSRAW options.
Redirect output using /LOG option for better performance.

/DCOPY:copyflag[s] :: what to COPY for directories (default is /DCOPY:DA).

/MAXLAD:n :: MAXimum Last Access Date - exclude files unused since n.
/MINLAD:n :: MINimum Last Access Date - exclude files used since n.
(If n < 1900 then n = n days, else n = YYYYMMDD date).

/XJ :: eXclude Junction points and symbolic links. (normally included by default).

/FFT :: assume FAT File Times (2-second granularity).
/DST :: compensate for one-hour DST time differences.

/XJD :: eXclude Junction points and symbolic links for Directories.
