Challenge

It is necessary to exclude specific databases on one or more Microsoft SQL Server instances from Veeam SQL Transaction Log backup processing. 
 

Solution

The following registry value is used to exclude databases from SQL Transaction Log backup. The exclusion will take effect during the next SQL Transaction Log Backup session.
 
Create this registry value on the server where Veeam Backup and Replication is installed.

Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: SqlBackupDatabasesToSkip
Value Type: String Value (REG_SZ)
Value Data: InstanceName:DatabaseName;InstanceName:DatabaseName

Take note of the formating, the registry value uses a colon between the instance name and the database name, and a semicolon is used to separate sets of instance and database pairs.

Notes: 

  • This exclusion registry value is not server-specific and will apply to every SQL server processed by SQL Transaction Log Backup.
  • Do not include the server name in the registry value, only the Instance Name and the Database Name.
  • The default SQL Instance, MSSQLSERVER, must be added to the rule as simply the word default.
     

Example:

The database "EDSHSD" in the instance named "SQLInstance" becomes SQLInstance:EDSHSD

Advanced Exclusion Techniques:

  • InstanceName:DBname 
    will skip databases with the specified name in an instance with the specified instance name.
  • InstanceName: 
    will skip all databases in any instance with the name specified.
  • :DBname 
    will skip any database with the specified name in any instance

 

Advanced example:

Exclude all databases named "Scratch" in any instance, all databases inside any instance named "DevTest", and the database "ProdMig" in the instance "SQLMigTest"

:Scratch;DevTest:;SQLMigTest:ProdMig
