Failed to read symlink - not a reparse point

I’m trying to back up files stored on a Windows server, and I’m getting a lot of the following symlink errors:

WARN LIST_LINK Failed to read the symlink _filename_: The file or directory is not a reparse point

I believe the files that are having problems are ones that were deduplicated using the built-in Data Deduplication feature in Windows Server 2012. The strange thing is, I’m running Duplicacy on two Windows servers, and I’m only having the problem with one of them. They’re both set up the same way - Duplicacy is running on a dedicated server, and backing up from DFS shares.

Does anyone have any ideas? The interesting thing is, the initial backup on one of my jobs completed successfully, but now it is having problems. I’ve tried restarting Duplicacy, running Duplicacy as administrator, restarting the server, backing up from server shares instead of DFS shares, etc., with no change in results.

If you run dir /a on that file/directory in the DOS prompt, what is the output?

They show up as regular files. Windows Server Deduplication is transparent to the end-user - the only indication that a file is deduplicated is the file properties dialog box shows the “Size on disk” to be 0 bytes.

We do have archiving software that moves old files off of the main storage, and puts symlinks on the main storage that link to the file that is in the archive storage. Those show up with <SYMLINK> in the filesize when running dir /a. Those are not backed up by Duplicacy, but there is no indication in the log file that they were skipped. (I have started another thread to discuss this problem.)

Just for example, here is a screenshot of Explorer showing a small portion of the files, and the corresponding dir /a output and log file. The .symlink file is a link to an archived file on another drive. None of these files are available to restore from my backup.

This is just to show the “Size on disk” property for one of the files. This file is deduplicated by Windows Server Deduplication.

And another edit: I have installed Duplicacy directly on the server, and set it up to back up directly from the drive instead of through a Windows share. Duplicacy is now happily backing up the files without errors. So at least I know I can back up the files.

However, this doesn’t fix the problem of Duplicacy not being able to back up the files from a different server. I’d still like to have my file server and backup server separate for management purposes.

@gchen Just want to make sure you saw my latest updates…

Wait, so you were backing up from a network drive that contained repairs point/symlink? It would not work of course – the symlink/reparse point would be getting resolved in the wrong namespace.

Yes, I want to back up a deduplicated Windows network share. Why shouldn’t that work?

If you want to know more about how Windows deduplication works, you can check out this site: Understanding Data Deduplication. Basically, the process should be invisible to end users and programs. In practice, we have been running deduplication for nearly 2 years, and this is only the 3rd program that I have run into issues with.
