This is a bit of an extension of this thread.. Robocopy silently missing files
I have a similar problem. I am using RoboCopy to copy files to a USB disk that will be transported to another location.
The log output is as follows:
Started : Thu Apr 26 04:33:18 2018
Source : \domain\Home\data\Users\User1\ (Network File Share) Dest : D:\User_Data\User1\ (USB Drive)
Files : *.*
Options : . /S /E /COPY:DAT /R:1 /W:1
The log output reports:
Total Copied Skipped Mismatch FAILED Extras Dirs : 22331 22331 0 0 0 0 Files : 226675 226675 0 0 0 0 Bytes : 94.972 g 94.972 g 0 0 0 0 Times : 7:05:25 6:52:13 0:00:00 0:13:12 Speed : 4122958 Bytes/sec. Speed : 235.917 MegaBytes/min.
However, a folder properties on the Network Share shows: 226319 files, 22275 folders
And a folder properties on the USB Drive
226613 files, 22322 folders
I need to account for the discrepancy..
We have also tried with various other switches..
/B (Backup) /IA:ASH (Hidden System Archive Set)
This made absolutely no difference.
The bit that is really strange is that NONE of the file and folder counts match up with the RoboCopy Log files. There are no errors or skipped files reported in the log output.
I am at a total loss. With 6 sample folders checked at Source and Destination, 4 are OK, 1 has a 1 file discrepancy and there is this one which is just weird..
I really would welcome any suggestions. I have never had a problem with RoboCopy before, we are regular users of this program.
My only thought was whether the properties actually counts real folders and files or just entries in the FAT.
