backup to NAS will not accept credentials

Thread needs solution

I have a NAS drive that I can access via Explorer and all other backup software but Acronis refuses to recognise the login credentials and keeps telling me that

"Connection Failed" and I am stuck at the "Authentication Settings" page

 

I need to backup to a NAS drive otherwise the software (just paid for) is no use to me

Can anyone suggest any helps

Many thanks

Phil

.... this exact same problem happens with two different NAS drives so I think it is definately reltated to Acronis rather than any hardware issues

Post back with your results, we are interested.

tried the "replace .... with fixed versions" and it seems to have recognised the drive now

 

Many thanks to Bobbo-3COX1 - whoever you are :)

Glad to help!  

I am having the same issue. I bought a WD PR4100 unit and installed the Acronis app on it. When I first ran the full PC backup it worked fine. Next time it failed, and I cannot even see the files I backed up.

I have replaced the two files as suggested - no difference.

I am not even sure what credentials it wants. On the authentications settings login window where it says Path:\\server\MyPc

 

there is boxes for user name and password.

Which ones though - my login to the NAS or my Windows logins?

In any case, neither work/.

edit: I have sorted out the issue. It seems that the problem was that I had created a new share folder on the NAS with the same name as my PC to be the recipient folder for the .tib files. I had subsequently changed the properties of that folder from Public to Private. My reasoning being that it should not or need not be private - and that Windows, Acronis and WD ought to be able to sort out credentials between them.

But no, as soon as I marked the folder Public it worked again. However the question remains, why cant I log into a private share on my own system when I have the user name and password of the server and my PC? What is it asking for?

Windows is limited to one network connection per user account - it's a Windows limitation.  By having one Windows share and another NAS share using the same name, any stored credentials, or credentials provided for the first device, will be used by Windows automatically to try and connect to the other device.

As you've found

1) Make sure the share names are different on each device 

2) if you want to use authentication on different devices at teh same time, you must use a different account for each

The reason it works when you set it back to public is that the Windows share remains with the provided credentials and the public share is now "open" so that you don't have to provide any credentials.

This is from an older MS KB Article, but the limitation for being able to authenticate to one remote share per logon still exists today.
