Hi,
I am receiving confusing results while using robocopy to move data. Normally we use evidence mover to transport data between drives or if we need to provide customers with results etc… For some reason, recently evidence mover kept crashing during the copy operation.
With no errors reported I was unsure what the issue was so we used Robocopy instead. Although robocopy worked (to a degree), the number of files in the source folder, destination folder and robocopy, were all different. For example, the source folder may have had 20,001, the destination had more 22,000, while robocopy recorded having moved 120,000 files (which of course it didnt.).
We have used Robocopy extensively in the past with no issues, I am in the process of doing file comparisons between all the results, but this will take time.
Has any one encountered this issue before. The source folder was from our forensic server, the destination was a normal external usb drive.
Thanks
Robocopy has always been reliable in my use. What switches did you use?
Are you copying from Sharepoint websites\WebDAV sources or other UNC file paths?
Source destination file/folder types and your full command line will be needed before we can help.
It appears Robocopy was right. The folder structure was just so deep, other tools weren't calculating the values correctly. Thanks for the response guys.
It sounds like you already found your answer, but I had this thought as well when reading your post. I have used /MIR (mirror) switch with robocopy especially when you are copying a source folder to a backup folder. You will want to be careful doing this, because it will delete any file in the destination folder that do not exist in the source folder. It keeps those folders nice and tidy so you do not run into a lot of variations of the same file, which could throw off your numbers as well. Just a tip and may be useful in the future.
It's also usually worth running robocopy over the folder in question with the /l (list) switch to verify the existence of long file paths that far too many applications still fail to acknowledge.
