Windows 7: Backup fails with error 0x8007007B

Windows 7 Upgrade Backup failure

Hi,
Someone asked me if I was using a dual-boot system, the answer is "No"
Breaking news, have just received a letter from Infoteam (Acer`s outsourced technical help agency) telling me to phone their tech. help line using an 0906 premium rate no. @ 50p. per minute !
After I had phoned them again on an 0870 no. and told them what I thought of them,they e-mailed me and told me that they had looked at the problem again and the only way to resolve it was to use the Windows 7 upgrade disk to carry out a clean install.
As I recall "Gregrocker" told me that this was the way to tackle the problem and that he himself had successfully done this.
It would appear that this is the only way to resolve the situation.
It is a thousand pities that Acer culd not have admitted that this course of action was necessary in the first place.
I think that I will take a break from all this for the New Year celebrations and then do the deed.

Happy New Year !

Thanks for the update, Peter.

Disgraceful of Acer giving you a premium rate number.

0870 numbers aren't cheap either ( that is a revenue sharing number - some goes to BT and some to Acer) - I deliberately do not deal with companies who won't give you a proper landline phone no.

If you discover after the fact you don't get a proper phone no. - you can usually get one from here - it's a free service - I love it:

There are two last-resort steps before clean installing by booting from the DVD:

Run sfc /scannow to see if any system files are missing or corrupted.

Run a Repair Install from the 7 desktop which is the next best thing to reinstalling but (like any Upgrade) can reimport corruption. But it might work.

It would be good to try all remaining options since including the error number in title of this thread means it will appear atop Google searches for years to come.

I refuse to re-install windows 7 just because I get this error 0x8007007B every time an automatic backup is attempted.
That would involve way too much work for this single error.
This is the only error that I encounter; nothing else is wrong with my system. It works perfectly to my knowledge,
except when an automatic system backup runs and it gets this error.
It runs for about 2 1/2 - 3 hours (I tried it yesterday and it got to 87% or 88% complete before it failed).

I am currently running a 3rd party's free backup program until Microsoft can fix this.

I purchased a 1TB Phantom USB drive strictly for the purpose of backing up my data.

Surely, a programmer at Microsoft can figure this problem out...

How many things can cause error 0x8007007B?

Let me know when someone there at Microsoft has a viable solution to this problem other
than re-installing the OS. We want to provide a real solution to others "googling" this error.

Thank you in advance.

Who suggested you reinstall?

Did you try sfc /scannow and Repair Install?

This isn't MS, we're volunteers here who try to help.

check if Volume shadow copy and windows backup services are running and set to automatic in Services Console.

1. Click on Start, type Services in Start Search. When the Services page is open, scroll the page to find Volume Shadow Copy and Backup service.

2. Right click on them and check if they are started.

3. If the services are disabled, start the services and set it to Automatic and check if the issue gets resolved.



If the services are running and you get Error Message: “0x8007007B - The filename, directory name, or volume label syntax is incorrect”, file name or volume label has special characters.



The system does not accept the keyboard combination Alt+0 through Alt+32 or the following characters: \\ \\ / [ ] : | < > + ; = . ? "



This gives the system an invalid path, so please correct the file name or volume label and make sure the username you are logged into has no spaces or special characters and then try to perform the backup.



It would also be caused due to Operating System shell corruption. If your file name and volume does not have any special characters and you are getting this error message, Create a new user account and perform the backup from the new user account and let us know if it helps.

The clean install was suggested by Acer to someone else with this same problem on this thread I started.
Everyone else was like "OK, before you re-install....."

I just stated that I was not about to preform another clean install for one problem.

No, I have not tried "sfc /scannow", but I did schedule a CHKDSK (Computer >
C: Properties > Tools tab > Error Checking, reboot. It found some errors and said it
would repair the files later during the process. I tried to do another scheduled backup,
but it was taking so long I had to stop it. It's kind of a shame it takes 2 1/2 - 3
hours and gets 88% completed before it gets the error 0x8007007B.

Do you think I should try the "sfc /scannow"?

Thank you very much!

Yes, try sfc /scannow. Then consider a Repair Install

I set both Volume Shadow Copy and Windows Backup services to Automatic, they were set to manual.
I also started them. I believe one was running, but the other was not.

The name of my PC is 10 characters long with 2 capital letters. I do not name the backup sets that the auto-backup creates. My user name is 4 characters long starting with a capital letter. I have tried the backup logged in as Administrator and I still get this error. I have Windows 7 Home Premium 64 bit, so not everything is supposed to be backed up. But, what I got from reading about it was that it did back up (each user's) documents, music, video, etc. It also creates a disk image to restore it if I want to doesn't it? I had been backing up these same user files on Vista before I installed Windows 7 and never had any problems. I was even triple booting Vista, Windows 7 RC 7100 and Ubuntu. I never had any problem whatsoever.

Then I did a clean install of Windows 7 and an install of Ubuntu; several weeks afterwords I started getting this 0x8007007B error.

I have "googled", searched high and low and all I could find was the Vista issue where there were 2 C: drives with 2 checkmarks and I do not have that.

I sincerely appreciate all of this help. I like Windows, but I do not need windows and I could easily use Ubuntu to perform all of my computing needs. But, I do not want to have to do that. My children have grown up using windows starting with version 3.1.

I will login as Administrator tomorrow morning and try it again and see if it works now. I will post the results. I have had enough of this thing for one day and besides today is my 25th anniversary. We will be going out to celebrate soon.
It sounds like you know exactly what causes this error and I am glad my problem will be solved shortly.

Thanks again!
