Hi, got a warning email from backup profile.

(Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))I’m tried to follow this but doesn’t work: https://www.veeam.com/kb3099Please anyone if you have clue or suggestion for this issue. Thank you.

To be sure about the reason of this error you need to check the VSS logs in the source machine.Usually they are located on C:\Programdata\Veeam\Backup. You should see files with the names:VeeamGuestHelperVeeamVssSupportThis could help to identify the problem.Also, it’s a good idea to run the command below to see if the Writer are all stable:vssadmin list writers

Hi, revise the information for Source and Destination:

Source using Win Server 2019
Destination/target using Win Server 2022

Hello @putu.nicho

Did you added the user who perform the backup to Backup Operators group?

Hi @Moustafa_Hindawi yes, we added to Local Users & Groups

Does the step above is correct?

Yes, it is correct! I prefer to contact Veeam support

Access denied is typically permission based error so I would double check all that. Also when using the username is it domain\username or hostname\username? Needs to be one of these formats.

Hi @Moustafa_Hindawi yes, we added to Local Users & Groups

Does the step above is correct?

Aside from checking the username format Chris mentioned, though the KB states to add the user to Backup Operators...did you try to add the user to the local Admin group just to see if that works?

To be sure about the reason of this error you need to check the VSS logs in the source machine.
Usually they are located on C:\Programdata\Veeam\Backup. You should see files with the names:

VeeamGuestHelper
VeeamVssSupport

This could help to identify the problem.
Also, it’s a good idea to run the command below to see if the Writer are all stable:

vssadmin list writers

Hi @coolsport00 yes, we did that, but still doesn’t work. Do you think its because of different version of Windows Server?

Source: Win Server 2019
Destination: Win Server 2022

Hi @wesmrt will try your suggestion and will let you know.

@putu.nicho - not likely. What kind of backup are you doing? Agent with VBR or Standalone Agent?

Just as a test try adding to local admins group.

Verify the service account on the Veeam console is correct with the correct password.

Make sure the service account is using the right syntax. Veeambackup\password vs veeambackup@domain.com\password

I’ve had the above catch me before using a domain account but not specifying it correctly.

Hi @wesmrt will try your suggestion and will let you know.

Hi @putu.nicho for me @wesmrt reply was perfect to solve your issue.

With vssadmin list writers command you receive a list of vss and its status.

This link can help you to know more on VSS.

Hi @coolsport00 we are using Agent with VBR

@Scott we did that already, still failed.
