How to intercept Robocopy output?

[Freddis]

Hi everyone, I'm learning programming with AUTOIT. I've put four lines of code in it to perform backups with the Windows 10 "Robocopy" command. I intercept an ERROR string in the log file, but sometimes it gives false errors, definitely because I didn't write it well. For this reason, I'd like your help in learning how to intercept the error and the exit code well. I tried writing it with windows script commands and it seems to work fine and also with AUTOIT but I think you need to change the interception method. I'll put the scripts in there. Thanks to anyone who would like to help me.parzial.batparzial.au3

robocopy "%SOURCE%" "%DEST%\Backup_Archivio" /E /Z /XJ /R:3 /W:5 /COPY:DAT /TEE /V /X /LOG:"%LOGFILE%"

if %ERRORLEVEL% EQU 0 set ESITO=OK: Niente da copiare
if %ERRORLEVEL% EQU 1 set ESITO=OK: File copiati correttamente
if %ERRORLEVEL% EQU 3 set ESITO=OK: File e cartelle copiate
if %ERRORLEVEL% EQU 8 set ESITO=OK: Backup ok, 1 file saltato - vedi percorso sopra
if %ERRORLEVEL% GEQ 9 set ESITO=ERRORE GRAVE: Backup fallito

not tested but should help

I have a request , can we do the same thing with the Robocopy GUI alternatives like Goodsync and Gs Richcopy360?

yes, you can but we would first like to see your own trials and source code you tried.
And most likely ask any AI assistant with above code to transform to your tools and you probably get a 98% finished script.
