To ignore errors and make Robocopy proceed without stopping, you can adjust the `/R` and `/W` switches in your command. The `/R` switch specifies the number of retries on failed copies, and the `/W` switch specifies the wait time between retries².
To force Robocopy to copy a file regardless of its condition, you can use the ‘/IS‘ and ‘/IT‘ switches in your command. The ‘/IS‘ switch includes the same files, and the ‘/IT‘ switch includes “tweaked” files 5.
Setting these to `B` will skip files that cause errors, and continue with the next files immediately.
Here’s how you can modify your command:
“`cmd
$Day = get-date -format 'yyyymmdd'
robocopy.exe "\\SAN\YourStore\Folder\" "D:\data" /M /TEE /DCOPY:T /COPY:DAT /E /R:0 /W:0 /MT:64 /XD ".TemporaryItems .Trashes $RECYCLE.BIN" /XD "System Volume Information" /XF ".apdisk" /XF ".DS_Store desktop.ini" /XF "Thumbs.db" /XF "*~$*" /XO /V /IS /IT /LOG:"C:\temp\$day-Robocopy_Log"“`
This command will now ignore all errors and proceed with the copying process.
NOTE: The file exclusion switch has a known bug, so that is why each exclusion is specified individually. –Patrick@Burwell.tech
