Troubleshooting:
Upon examining the file involved with the failure (in this example the file in question is "example.dat"), an alternate data stream was found.
1. Within Windows Explorer, right-click the file and choose Properties > Summary tab. Note whether any of the fields such as Title, Subject, Author, Category, Keywords or Comments are completed
2. From command-line, run:
fsutil objectid query example.dat
Object ID :        a35eb8fb0f5add1196e2000c296db9bf
BirthVolume ID :   261ec36f17c2874a92c7d1dd30550edb
BirthObjectId ID : a35eb8fb0f5add1196e2000c296db9bf
Domain ID :        00000000000000000000000000000000

NOTE: if an object id is returned by the fsutil command, then this file would trigger the backup failure.
