BUG: File History fails with no warning- Event ID 201

Question

I apologize for the long post but I want to summarize everything I've learned about this so far, as it looks like a critical bug.
I am unable to get File History to backup my files with Windows 8.1.  I set up a 1 TB USB HDD as the target drive and it seemed to run for a minute or two, and then quit completely without any warning.  It created two empty folders on the target
HDD, but no data was backed up.  I then clicked "Run Now" to try and get it going again, but nothing happened. 
Under "Advanced Settings" I opened the event log, and saw an Event ID 201 was created each time File History attempted to run: "Unable to scan user libraries for changes and perform backup of modified files for configuration C:\Users\MyUserName\AppData\Local\Microsoft\Windows\FileHistory\Configuration\Config". 
I've pasted the entire error below.  The "Event Log Online Help" link opens to "Page not Found" on TechNet.
A Google search revealed other users are experiencing this problem, too (links below).  Some people have been able to solve it by excluding libraries and/or moving all of their data out of the libraries then replacing it one folder at time, running
FH, and repeating until they find the "offending" file by error 201 occurring.
There are reports of similar problems with Event IDs 202, 203 and 204.   A similar, but separate error is "Unusual condition was encountered during scanning user libraries for changes and performing backup of modified files for configuration C:\Users\MyUserName\AppData\Local\Microsoft\Windows\FileHistory\Configuration\Config". 
Based on others' posts, the problem appears to be a bug in how FH handles files/folder names that are similar,
contain unusual (but legal) characters, and shortcuts ("reparse error").   The second bug is, regardless of which Event ID, that
FH does not alert the user when it fails, so you have no idea your files are not being backed up.  Even if you are able to eliminate the problem once, there is no guarantee that it won't happen again.  Once error 201 occurs, File
History is dead in the water and unfortunately since Windows 7 File Backup was removed, there is no alternative data backup method available.
If anyone has an idea of how to solve or work around this problem (i.e. under exactly what filename conditions FH fails), please post.  I have Windows 8.1 installed on drive C, Windows 7 on drive D, and a data partition E onto which I moved all my Libraries. 
The Win 7 and 8.1 libraries are in separate folders and not linked in any way, so 8.1 is not trying to back up 7's data.  However, the partition arrangement does not appear relevant.
Thanks!

Hi, thanx for the post. It helped me to fix my Problem with file history.
In my case it was the spelling of some files. I'm German and we have some Special chars like ä,ö,ü and ß.
The "Problem" is that You can spell These also in a different way for example "ä" is same like "ae" and "ß" is same like "ss" .
If I Name one file like "groß.txt" and the other one "gross.txt" file history won't work! I don't know why, probably MS conversts the Name in the background or whatever - but this really
sucks!
Even more that You don't get informed! Only when checking the eventlog - and not even in the "normal" eventlog - You have to go to "Microsoft-Windows-FileHistory-Engine/BackupLog" - well, how often does one look up this??
I think file history is quite useless in this state as it does not inform the user about Problems with the backup. And I really don't want to get "informed" when I Need to restore some files...
Cheers
