Then, I deleted the symbolic link with rmdir c:\s to clean up, and that was that! Now, I can look at this linked version in Explorer, and copy the data! As explained in the blog post, I didn’t forget to add a trailing slash to the mapping (it won’t work if you don’t do that). The link is from a very short-named local folder to the “ Shadow copy device name” given in the listing. Symbolic link created for c:\s \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy266\ Well, the trick was on a Microsoft blog - using a symbolic link to get to the shadow copy:Ĭ:\Users\Administrator\Desktop> mklink /d c:\s \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy266\ Because the shadow copy is accessible to the client (through Previous Versions), I couldn’t directly map it to a drive. The GUID in the expose command is the “ Shadow copy ID” given in the listing. * Shadow copy ID = P:Ĭlient accessible shadow copies cannot be exposed. In this case I wanted the 10:41:53 AM snapshot on Janufor the C: drive, which looked like this in the log: I listed them to a file (I used diskshadow for consistency, although vssadmin would also let me do that piece), then searched the file in Notepad:Ĭ:\Users\Administrator\Desktop> diskshadow /l shadows.txtĬ:\Users\Administrator\Desktop> notepad shadows.txt Let’s see what happened, then explain a solution.įirst, we find the exact name of the shadow copy.

The first one that I thought of – to use the diskshadow command that is new in Windows Server 2008 – didn’t work as I expected. There are multiple ways to go about this. The answer is to surface or expose the shadow copy as a drive letter. Anyway, this still leaves the problem of getting a shorter filename. I suspect Explorer still cares due to backwards compatibility, which is why the Unicode 32K path length doesn’t come into play, but that’s just a guess. Well, the reason the path is too long is because with the shadow copy overhead added to the path, the filename has a length longer than MAX_PATH, or 260 characters. Questionable grammar aside, the error’s suggestions, which relate to changing the source, are useless, because shadow copies are read-only. Try moving to a location which has a shorter path name, or try renaming to shorter name(s) before attempting this operation. The source file name(s) are larger than is supported by the file system. Why is the long name a problem? Well, when I tried to copy the folder out of the shadow copy, I got this 100% correct yet not helpful error: \\localhost\C$\Users\Administrator\Desktop\Somewhat Long Folder Name\Another really long folder name for a good reason that you do not know\Yet another long nested folder name believe it or not (Today, January 26, 2012, 12 minutes ago)\Long file name here as well that will be a problem for us soon.txt It turns out this file is nested a few levels deep in a set of long folder names, and has a long filename as its exposed filename: I clicked Open on the Previous Versions tab, then navigated through Explorer to the folder that has the file I want to get. So, we have the previous state of the folder, it’s in a local snapshot, so I could get it back, right? Let’s see what happened. In fact, this was through a shadow copy, which will turn out to be very important: I first made sure there was a previous version available: (A backup was not available on the particular folder for reasons I won’t get into here.) I ran into a problem that I couldn’t really find documented very well anywhere and thought I would document it for others. I was working on a server the other day and needed to recover files from a previous version of a folder through Previous Versions.
