Backup for M365: unable to add repository via SMB

It looks like you need to just specify the shared folder and not add the “FOLDER-NAME” to the path.

See here - Network Attached Storage (SMB Shares) - Veeam Backup for Microsoft 365 Guide

Also something to note on that page above -

Keep in mind that Network Attached Storage repository is on experimental support.

Hey Chris: I have tried that, I get the exact same error (but without the added folder name of course)

The other thing to check would be permissions - yes, I know you said you configured them but a double-check is always good.

Otherwise, you could possibly try a mapped network drive on the Proxy server for VB365, but this is not a recommended method either.

Last thing is Support and opening a case.

Thanks for the tips Chris, I appreciate it. I just checked permissions again, and they all look good (I can browse to the folder via Win explorer, logged into Windows as the same AD account I use to log into Veeam.)

I have the shared folder mapped as a network drive, but it does not show up under the Veeam host if I click “Browse.”

So then network mapped drives don’t work and it wants local drive.  So, at this point I would suggest a support ticket if you really needed to get this working.

Glad to hear you were able to solve the issue and post the answer to help others.

Thanks Chris, appreciate your replies to help guide in the right direction.

Not a problem.  That is what we are here for.  😉

Thanks for posting your answer...I would have not considered granting permissions to the server rather than a user.  Good information to know.  The think I probably would have done differently is connected to the NAS via ISCSI rather than SMB so that it appeared as a local volume and I didn’t have to mess with SMB permissions, etc.  Glad you got it working though.

Hi,

I have the same problem trying to add SMS repository shared from Synology NAS. I follow your solution but return “username and password is incorrect”.

The NAS and Veeam server are in the same domain. I add permission to the veeam server for the shared folder, and for the user used to login in veeam. 

I have other backups copies in the volumen NAS, so the iSCSI solution for me, is not an option. 

Please any idea, maybe I’m ignoring something.

Thanks

Did you read the solution?  It mentions granting permissions to the Veeam Computer Account not user.

permissions on the NAS need to be granted to the Veeam server (not the Windows user account used to log into the NAS or the Veeam server). As indicated in “Scenario 1” in the below linked article

Hi ​@Winsys Seens to be permission as well, wuold you mind to double check the permissions? just in case.

Hi Chris, 

Thanks for your quick reply.

Yes I do that.

I give permissions in the shared folder to my Veeam Server. 

Hi Chris,

Ok then it should work.  Maybe ​@monkthecat can explain and help you out more.

​@Winsys The permission listed up above is for the VCN adm, , how it is for the IT-Veeam?

If you read the answer to the thread you need to grant permissions to the Veeam Server (not user account).  The KB posted details this out.

​@Winsys: ​@AndrePulia is right: have a look at your screen grab, you have “CVN Admin” selected, be sure you click “IT-VEEAM12” (looks like that’s the name of your Veeam server), and make sure permissions are correct there.

​@monkthecat Thank you!!

Hi everyone,

Thanks for your replies.

Yes I give the modify permssion to my veeam server:

But the error persist. Any other idea. 

Thanks

This is the error

Are you typing the Path or clicking browse to see if you can choose it that way?  Browse will tell you if it is working but I have never seen a path added in that format which is probably the issue.

Thanks ​@Chris.Childerhose.

When I try browse, only let me browse locally in the hard drives server

The format is correct: see it in this KB article: Network Attached Storage (SMB Shares) - Veeam Backup for Microsoft 365 Guide

Thanks

In that article for the NAS SMB share the format is - \\server\share name --- you have more than that in the path you posted.  Is the shared folder called “O365_Winsystems”?  If so then it should be for your path - \\10.1.40.52\O365_Winsystems

If the other path is the shared folder then I am unsure why it is not working.
