Hello everyone.
I've a lot of people encounter problems similar to this, but here is my particular flavour:
I have a Windows 8.1. Pro (64 bit) desktop PC.
I am trying to use File History > System Image Backup to create a backup image of my C: drive.
I have been trying to save the backup both an external USB 3.0 drive, and this time to a network location (on a WD 'MyCloud' EX4 NAS)
Every time, the backup fails about 3/4 of the way through.
I get an error dialog saying
"The backup failed. The operation failed due to a device error encountered either with the source or the destination. If the source or destination volume is on a disk, run CHKDSK /R on the source or destination volume, and then retry the operation. (0x8078012D)Additional Information: The request could not be performed because of an I/O device error. (0x8007045D)"
I've spent many hours diligently running CHKDSK /R both on my C:\ and the destination drives, and it has never once found any problems.
I've tried closing all applications, unnecessary services, background processes and disabling Windows Defender's real time malware checking whilst the backup takes place, but that doesn't seem to fix anything.
My hunch is that there's nothing wrong with the disks or hardware at all, and that this is some kind of obscure permissions problem, where Windows can't access symbolic links on my C: drive.
But I basically haven't a clue! :)
I'd be very grateful for any suggestions at fixing this, as currently I don't have any backup image of my C:\ drive, so if my PC goes kaputt, I'll have days of manual re-installing and configuring to do.
Thanks.

Thanks for update.
That's good news.
Does system you perform Win 10 upgrade on have same disks in system that you had when you originally opened this thread?
Hopefully system backup will continue to work.
How you going to verify backup is good?
Are you ever going to purchase another disks and restore backup to it to verify and confirm backups created are restorable?
Feline where are you gographically? 1 am in morning is pretty early unless you're in different timezone or hemisphere.
well, I started this monster of a thread about 18 months ago, and I've now upgraded the PC in question to Windows 10 Pro (64 bit)... and this has solved the problem!
One of the first things I tried doing with Windows 10 was making a System Image Backup via Control Panel > File History
It failed as usual :)
HOWEVER: the error message was different - it specifically referred to bas clusters on the source drive. I right clicked on my C: drive in file explorer, and ran the disk checker utility in the properties tab. This is no longer CHKDSK, but something that runs in the Windows GUI rather than in command prompt. It still needed to reboot my machine to repair the clusters, but it fixed them. When I then tried to create a System Image Backup again, it succeeded for the first time in about 3 years Hurrah!
It looks to me like it was CHKDSK that was actually the problem all along: perhaps it couldn't deal correctly with an SSD drive? whatever the case, Windows 10's disk repair utility fixed clusters that CHKDSK couldn't.

RESOLVED: As you all know, System Image Back to WD My Cloud using the native image backup utility in control panel fails when a login and a password for the target NAS. The solution is to use a password protected account (enable password for one of the users using the WD My Cloud Dashboard) using level down format as such: WDMYCLOUD[USER_NAME], where WDMYCLOUD is the name of the NAS server that is displayed on the NetBIOS Network.
backup files in ESP partition and delete ESP partition by using disk manage tool, e.g. paragon, recreate ESP partition and copy backup files to the new esp partition, the problem may be solved.
