Copy Options Option Description
/S copy Subdirectories, but not empty ones. /E copy subdirectories, including Empty ones. /LEV:n only copy the top n LEVels of the source directory tree. /Z copy files in restartable mode. /B copy files in Backup mode. /ZB use restartable mode; if access denied use Backup mode. /J copy using unbuffered I/O (recommended for large files). /COPY:copyflag[s] what to COPY for files (default is /COPY:DAT).
(copyflags : D=Data, A=Attributes, T=Timestamps, X=Skip alt data streams).
(S=Security=NTFS ACLs, O=Owner info, U=aUditing info).
/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. /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. /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. /DCOPY:copyflag[s] what to COPY for directories (default is /DCOPY:DA). (copyflags : D=Data, A=Attributes, T=Timestamps, E=EAs, X=Skip alt data streams). /NODCOPY COPY NO directory info (by default /DCOPY:DA is done). /NOOFFLOAD copy files without using the Windows Copy Offload mechanism. /COMPRESS Request network compression during file transfer, if applicable. /A copy only files with the Archive attribute set. /M copy only files with the Archive attribute and reset it. /IA:[RASHCNETO] Include only files with any of the given Attributes set. R – Read-only A – Archive S – System H – Hidden C – Compressed N – Not content indexed E – Encrypted T – Temporary /XA:[RASHCNETO] eXclude files with any of the given Attributes set. /XF file [file]… eXclude Files matching given names/paths/wildcards. /XD dirs [dirs]… eXclude Directories matching given names/paths. /XC eXclude Changed files. /XN eXclude Newer files. /XO eXclude Older files. /XX eXclude eXtra files and directories. /XL eXclude Lonely files and directories. /MAX:n MAXimum file size – exclude files bigger than n bytes. /MIN:n MINimum file size – exclude files smaller than n bytes. /MAXAGE:n MAXimum file AGE – exclude files older than n days/date. /MINAGE:n MINimum file AGE – exclude files newer than n days/date. /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). /DST compensate for one-hour DST time differences. /XJ eXclude symbolic links (for both files and directories) and Junction points. /XJD eXclude symbolic links for Directories and Junction points. /XJF eXclude symbolic links for Files. /IM Include Modified files (differing change times). /R:n number of Retries on failed copies: default 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 share names To Be Defined (retry error 67). /LFSM Operate in low free space mode, enabling copy pause and resume /LFSM:n[KMG] /LFSM, specifying the floor size in n [K:kilo,M:mega,G:giga] bytes. /RH:hhmm-hhmm Specify the time between the job can run /ZB Copy files in restartable mode; restart the copy action in backup mode if access is denied. This will override files and folder permissions that might block access. /MT:n Multi-Threaded will speed up the file transfer, n = default 8 /IPG:n Limit bandwidth usage by telling Robocopy to wait n milliseconds /R:n Specify the number of retries /W:n Specifies how long to wait between the retry /LOG:<path> Specify the log file to save the information to /LOG+: Append the result to an existing log file /ts Include the source file time stamp in the log output /tee Output to log and console /fp Include the full path of the files in the log /v Verbose, output also skipped files
