Microsoft SQL Server Transaction Log are not truncated due to an error code 0x80004005 [TLS 1.0]


When backing up a machine running a Microsoft SQL server where TLS 1.0 has been disabled, a job may fail with the error code 0x80004005 [TLS 1.0].

The following warning will be found on the server that is being protected by either Veeam Backup & Replication or Veeam Agent for Microsoft Windows, the path to the file containing this warning is listed below.

  • For a VM being processed by Veeam Backup & Replication:
  • For a server being backed up using Veeam Agent for Microsoft Windows:
INFO    Connecting to mssql, connection string: Provider='sqloledb';Data Source='(local)\SQLINSTANCENAME';Integrated Security='SSPI';Persist Security Info=False, timeout: 15 
WARN        Code = 0x80004005 WARN        Code meaning = Unspecified error 
WARN        Source = Microsoft OLE DB Provider for SQL Server 
WARN        Description = [DBNETLIB][ConnectionOpen (SECCreateCredentials()).]SSL Security error. 
WARN    COM error:  Code: 0x80004005


The SQL Server being protected by Veeam is using a SQL OLE DB provider which does not support TLS 1.2


The direct solution to this situation is to review available updates for the SQL Server that is having this issue and ensure that TLS 1.2 is supported by the Microsoft OLE DB provider for SQL Server.

Please review:

As a workaround, it is possible to force Veeam to request that the 'Native SQL Client Provider' be used instead of SQLOLEDB. This is done by adding a registry value to the Guest OS of the machine being protected by Veeam.

Please review the scenarios below and use the location and value specified:

  1. For a VM being protected by Veeam Backup & Replication:
    • Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
    • Value: UseSqlNativeClientProvider
    • Type: DWORD
    • Data: 1
  2. For machines being protected (managed or standalone) by Veeam Agent for Microsoft Windows:
    • Location: HKLM\SOFTWARE\Veeam\Veeam Endpoint Backup
    • Value: UseSqlNativeClientProvider
    • Type: DWORD
    • Data: 1
  3. For SQL Failover Clusters protected by Veeam Agent for Microsoft Windows via a job in Veeam Backup & Replication with the option Backup logs periodically an additional value must be specified (the value in  HKLM\SOFTWARE\Veeam\Veeam Endpoint Backup also still remains the place).
    • Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
    • Value: UseSqlNativeClientProvider
    • Type: DWORD
    • Data: 1

No server restart is required, registry key will be checked on next job run.
