If you need to exclude a database from transaction log processing (without excluding the database itself from application-aware VSS processing), you can use the following methods:
- Set database logging model to simple - then no log file will be created for this database, and log processing job ('child') will not be run for it.
- Create a list of databases to be excluded from transaction log processing. For that, you will need to create the following registry entries under HKLM\SOFTWARE\Veeam\Veeam Backup and Replication:
Registry entry | Type | Default value | Description | Examples |
SqlBackupInstanceDatabaseDelimiter | REG_SZ | : | Specified character string will be treated as a delimiter between InstanceName and DatabaseName in a list entry. | sql_instance_name: - skip all databases from such SQL server instance (for example, sql_2014:) :db_name - skip all databases with such name on all instances (for example, :master). |
SqlBackupInstanceDatabasePairsDelimiter | REG_SZ | ; | Specified character string will be treated as a delimiter between list entries. | sql_2014:;:master |
SqlBackupDatabasesToSkip | REG_SZ | None | Instructs Veeam to exclude SQL databases from transaction logs backup process. Databases and instances should be listed using the delimiters described by the SqlBackupInstanceDatabaseDelimiter and SqlBackupInstanceDatabasePairsDelimiter | sql_intance_name:db_name - skip everything which contains such instance and database name sqlserver:msdb;sqlserver:model;:master;sqlserver: |
If database name contains default delimiter character(s), you can use any other character or character string as delimiter when creating a list of exclusions. For example, if SqlBackupInstanceDatabaseDelimiter value is set to ###123###, then SqlBackupDatabasesToSkip will contain a list of entries like this:
sql_instance_name###123###db_name_1;sql_instance_name###123###db_name_2
Excluding Veeam Backup Configuration Database
Remember the following:
- Veeam Backup & Replication automatically excludes its configuration database from application-aware processing during backup, if this database is hosted without using SQL Server AlwaysOn Availability Group. Transaction logs for the configuration database are not backed up.
- If the configuration database is hosted using SQL Server AlwaysOn Availability Group, then you should manually exclude this database from application-aware processing during backup, as described in this Veeam Knowledge Base article. Otherwise, job processing will fail with the following error: Failed to freeze guest over network, wait timeout.
