0x80070002 from Windows Backup is a fairly generic "file not found" error in the backup engine, so the cause can be anything from a missing source path to a Volume Shadow Copy (VSS) failure. 's suggestions (the KB and the admin/WMP items) are valid first‑line checks, and since confirms those were tried, the next step is to look at system‑level diagnostics and the backup target itself.

A compact troubleshooting checklist that fills gaps left by the earlier replies:

  • Inspect Event Viewer (Application and System logs and any Backup/VSS entries) for the precise failure text or Event ID; that usually points to which file, service, or writer failed.
  • Confirm the backup destination is reachable, formatted NTFS, has plenty of free space and correct permissions; network shares must be accessible with valid credentials.
  • Ensure the backup selection contains no offline/missing items (mapped drives, disconnected USBs, removed user folders). Windows Backup aborts if a selected path cannot be found.
  • Check VSS writer status and overall system file/volume health; VSS or corrupted system files often stop image/file backups.
  • If a previous system image/catalog on the destination is corrupted, creating a fresh catalog (by moving/renaming the WindowsImageBackup folder on the target) often lets a new backup complete — but that will remove access to older images.

Common diagnostic commands (run from an elevated command prompt):

sfc /scannow
vssadmin list writers
chkdsk /f D:

Replace D: with the relevant drive letter. These help surface VSS writer errors, system file problems, and disk issues.

If none of the above reveals the problem, a practical workaround is creating a file-only backup to a different physical USB disk or using a trusted third-party imaging tool to capture the system while the underlying cause is investigated. The Event Viewer/VSS messages are usually the best clue to a specific fix.

and if that doesn't work try this , info from another site.

the backup fails with the 0x80070002 error :

1) The built-in administrator account is disabled (it is disabled by default in Win7)

2) The Windows Media Player Network Sharing Service is enabled

*Possible solution (!!Use at your own risk!!):

--------------------I recommend doing both ---------------------------

1) Enable the built-in Administrator account (you can disable it again after backup), this can be done several ways. The two most common ways are:

From elevated cmd prompt type: net user administrator /active:yes

OR
Right-click Computer
select Manage
expand Local Users and Groups on the left by clicking the little arrow
select users
right-click Administrator and select properties
un-check 'account is disabled'
click Apply
click OK

2) Disable the Windows Media Player Network Sharing Service , this also can be done several ways. The two most common ways are:

msconfig
click the Start Menu
type msconfig in the "search programs and files" entry box (or from Run dialog box)
select the Services tab at the top of the window
un-check the Windows Media Player Network Sharing Service
click Apply
click OK (you may see some warnings or notifications, click OK)
restart the computer

OR
services.msc
click the Start Menu
type services.msc in the "search programs and files" entry box (or from Run dialog box)
select the Windows Media Player Network Sharing Service fro the list at the right
right-click it and select properties
set Startup type to disabled
click Apply
click OK
restart the computer

3) Backup the computer

I hope this helps.

Thanks, I did both but still get the same error message. In this aspect I think Microsoft sucks
