A few weeks ago I wrote about using XCopy to copy files and folder structures including their NTFS Permissions. Recently I came to the point where I wanted to see all errors and their related files, so I could fix messed up NTFS permissions. With XCopy however parsing the log is pretty much impossible. Also Microsoft suggests using RoboCopy as a sucessor to XCopy. And thats what I did.
Using RoboCopy like XCopy
In my other blog post I meantioned that I wanted to copy all folders and files including their NTFS permissions and ignore errors on the way. You can do the same thing with RoboCopy and it is a lot faster.
To achieve the same result you can use the following command to keep directories in sync.

Okay let’s go over the switches line by line.
| Parameter | Description |
|---|---|
| /MIR | Mirrors the source to the destination dir copying all files and folders, including empty ones. |
| /SECFIX | Fixes security permissions on already copied files (you can leave this out if you want) |
| /COPYALL | Copies all files attributes including NTFS permissions. |
| /R:0 | Number of times to retry copying a failed file. |
| /W:0 | Wait time between retries. Defaults to 30 seconds. |
| /LOG:file | Logs output into the givenfile. |
| /TEE | Logs output to console and logfile. |
You can always see a full list of switches with /?.
Parsing RoboCopy error log
With RoboCopy we now get parseable log files and can use this nifty script from the Technet Gallery to extract all failed files from the logs.
