There are no problems, only solutions.
Basically that says is it's an incorrectly configured backup. You might want to check this out:
It relates in some circumstances you can ignore that error code. If you get an error code some thing is not right and in my opinion it should not be ignored. It should be resolved. Sometimes it's as simple as updating drivers or as complicated as resolution 2 in that link. Hoo boy, whew. Talking about jumping through hoops to solve a problem.
I started using this 2 weeks ago and let windows run the show. I'm not interested in backing up my personal files with this program. I do that manually twice a week on my WD MyCloudMirror NAS box. I could have this program dump the output to the nas box as it perceives it as just another drive. But with windows running the show the output files are pretty big. When the 500giger starts to get a wee bit tight for space I'll run the backup cleanup program and get rid of backups over 2 weeks old.
Anyway give it a read and decide what you want to do. BTW what brand hard drive is that in your computer?
