There is a 2013-era ps1 robocopy script at: [https://gitlab.com/ltog/robocopy-backup](https://gitlab.com/ltog/robocopy-backup) Note also that ["if you want robocopy to ignore all return codes under 8 (>= 8 means copy error)"](https://stackoverflow.com/questions/44504795/how-to-stop-robocopy-from-exiting-the-build) you may need something like the following in your .cmd/.bat script: ``` (robocopy src dst /mir) ^& IF %ERRORLEVEL% LSS 8 SET ERRORLEVEL = 0 ``` or the equivalent in Powershell ``` robocopy src dest /mir; if ($lastexitcode -lt 8) { $global:LASTEXITCODE = $null } ``` Below is example of log file created by MAP's robocopy script that shows command line options. ``` terminal ------------------------------------------------------------------------------- ROBOCOPY :: Robust File Copy for Windows ------------------------------------------------------------------------------- Started : Mon Oct 21 17:34:18 2019 Source : D:\MassHunter\Data\2019\ Dest : x:\Data\2019\ Files : *.* Options : *.* /NDL /NFL /TEE /S /E /COPY:DAT /DCOPY:T /PURGE /MIR /NP /XJF /XJD /R:1000000 /W:30 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ Total Copied Skipped Mismatch FAILED Extras Dirs : 30998 30998 0 0 0 0 Files : 119242 119242 0 0 0 0 Bytes : 138.923 g 138.923 g 0 0 0 0 Times : 2:00:16 1:46:01 0:00:00 0:14:14 Speed : 23449086 Bytes/sec.
