Windows 7 Backup System Image - Error Code 0x8078012D - fails to complete system image backup?

Question

I seem to have a problem with Windows Backup when a scheduled image backup to an external hard drive fails to complete, although it has worked successfully before on many occasions.  Windows Backup reports an error code of 0x8078012D. 

I have run the Error Checking tool on the external drive with both the repair options switched on, but no problems discovered.  The external disk drive seems ok as I use a Norton program to back up data to the same drive without any problems.  Also Windows Backup will happily do a 'non system image' backup on the external drive.

But it will not do a stand alone system image nor one as an add on the a normal backup.

Any advice?

Thanks

After many tries at the solutions listed here I found a way to fix my problem. I continually got a failure basically saying the system could not create a shadow copy or that my drive had a failure. It seems with Windows 7 you have to configure some options that are not apparent to users.

1. go to control panel/system/System Protection and select your C: drive.
2. Select "configure" and make sure "Restore system settings and previous versions of files" is on.
3. Set Max Usage to at least 2%
4. Apply
5. Select your USB drive you will be using for backup and again Configure it for protection and set the file size to at least 18%.
6. apply
7. back in the control panel go to Administrative Tools, open Services.
8. Scroll down to Windows Backup and make sure it is set to Manual and not started.
9. Scroll to Volume Shadow and make sure it is also set to Manual and not started.
10. Go back to the control panel, select Backup and Restore.
11. Click "Change Settings" and select the drive you will be backing up to.

12 Run backup letting the system do it's thing and all should work.

Yet another dis-functional windows service!  Iam usint a windos 7 64bit recovery disc and restoring from a USB hard drive to a NEW internal drive so obviously no AV softwareas there is nothing on the drive, no services to re-enable as there is no O/S installed

Any ideas??.......Anyone

Just an extra comment to the above - I think I have established that the external drive is not the problem.  This is because I tried a second external drive and got the same error message so presumably the problem lies with Windows Backup.

Any ideas out there?

Thanks in advance

The error might have occurred if the services related to Windows backup might have been disable, you may try restarting the service, follow the steps below:

• Click Start.
• Type Services in the Start Search.
• In the Services Windows search for Volume Shadow Copy in the list.
• Right click on the Service.
• Click on Properties.
• Select the Startup Type to Manual.
• Click OK.
• Now repeat the same for Windows Backup service.

 

Also Turn off the Norton and you should able to backup,if it doesn't works do let us know

Thanks Ankur Mittal

No go - I am sorry to say.  Both the services settings were already set to Manual so no need to change ( although I did reset them to Manual, just in case) and I switched off Norton Backup.  But the backup failed with the error message -

"The operation failed due to a device error enccountered with either the source or the destination.  If the sourrce or destination volume is a disk, run CHKDKSK/R on the source or destination volume, and then retry the operation.  Details: the request could not be performed because of an I/O device error.   + error code 0X807801D"

I think that I have already run CHKDSK, assumig the Windows tool 'error checking' is the same thing.

Any thoughts?   Strangely it has always worked before so somehow I or something has changed something.

Thanks for your help
