Windows 10: Error code 0x80780166 when attempting Windows Backup/Restore

Hi,

When attempting to back up to external hard drive, receive the following error code:

0x80780166 and message STATUS_WAIT_2

System is running Windows 10 Pro and the external drive should have enough space. Computer has 4GB RAM, 64bit, 3.10ghz processor

Ideas?

Getting error 0x80780166 backing up windows 10

Hello, I made sure my VSS is set to automatic and is running correctly. I have tried repeatedly to create a windows backup on my 1TB USP external hard drive and EVERY time I get the same error that the backup cannot find specified file. The backup does not
complete as a result of this error (0x80780166). I am trying to run the backup with the Backup tool (Windows 7). Any ideas on what else I can try to get the backup to work? Thank you.

As you are facing error 0x80780166 while backing up on Windows 10, do let us know the following to assist you better:

As a work around, I suggest you to check if the Volume Shadow Copy service
(VSS) is running properly.

Steps:

• Press Windows + R to open Run
  command, type Services.msc and press
  Enter.
• Search for Volume Shadow Copy
  Service, right click on it and
  start the service.
• Also, set the Startup type to Automatic.
• Log-out from the current user account, restart, re-log-in and check if the issue persists.

Also, I suggest you to refer to Microsoft article about:
