Hello, I’m Virginia an independent advisor with 20 years of expertise in fixing my own & friends’ PC problems.
Which Windows are you running? Some of the files suggest Windows 8.1.
Which program are you using for backup?
Some of the folders seem to be cloud related (SkyDrive/OneDrive) so perhaps these folders aren’t accessible to the backup program.
The error suggests problems with the hard drive so try this program to see if there’s a problem:
I’d also recommend running chkdsk on both C drive & the drive you’re backing up to:
Cmd with admin & enter:
chkdsk C: /r for C drive For the backup drive just enter the same cmd but change C: / for the drive letter of the external drive.
Also run:
Right click on start & choose powershell with admin & enter:
SFC /SCANNOW
DISM /Online /Cleanup-Image /StartComponentCleanup
DISM /Online /Cleanup-Image /RestoreHealth
If this doesn’t fix the backup problem:
Windows backup & maybe in the future file history are being deprecated & will eventually be removed, what you’re experiencing may be related to that.

Microsoft recommend using third party software:
“System Image Backup (SIB) Solution
We recommend that users use full-disk backup solutions from other vendors.”

I recommend moving to third party imaging software now before it is removed permanently if you prefer backing up your PC rather than using File history.
