Script that uses environment variables to exclude instances and databases from backup(NetBackup for SQL Server)
You can use SQLINSTANCE $ALL in your batch file to designate that all SQL Server instances on your host be backed up. For example, the following batch file backs up the master, model, and msdb databases. These databases are backed up on all instances of SQL Server on the host on which the batch file is run.
SQLINSTANCE $ALL OPERATION BACKUP DATABASE "master" NBSERVER "BEARING" MAXTRANSFERSIZE 6 BLOCKSIZE 7 NUMBUFS 2 ENDOPER TRUE OPERATION BACKUP DATABASE "msdb" NBSERVER "BEARING" MAXTRANSFERSIZE 6 BLOCKSIZE 7 NUMBUFS 2 ENDOPER TRUE OPERATION BACKUP DATABASE "model" NBSERVER "BEARING" MAXTRANSFERSIZE 6 BLOCKSIZE 7 NUMBUFS 2 ENDOPER TRUE
To exclude SQL Server instances on your host from backup, create the Windows environmental variable NB_SQL_INSTANCE_EXCLUDE. Specify a list of instances names that you want to exclude. The list should consist of one or more names that are separated by semi-colons.
For example, use the following value to indicate that you want to exclude the default SQL Server instance and the instance named ABC-PRODUCTS from backup:
#DEFAULT#;ABC-PRODUCTS;
Note that the default SQL Server instance for the local host is designated as #default#.
You can also exclude individual databases from backup by creating a Windows environmental variable NB_SQL_DATABASE_EXCLUDE. For the value of the variable, specify a list of database names.
For example, consider the following batch file:
SQLINSTANCE $ALL OPERATION BACKUP DATABASE $ALL NBSERVER "BEARING" MAXTRANSFERSIZE 6 BLOCKSIZE 7 NUMBUFS 2 ENDOPER TRUE
You can exclude the databases "master," "accounting," and "pubs" with the NB_SQL_DATABASE_EXCLUDE environmental variable. For the value of the variable, indicate the databases you want to exclude. Separate the database names with semi-colons.
MASTER;ACCOUNTING;PUBS
The NB_SQL_DATABASE_EXCLUDE variable is applicable only for a batch file that has DATABASE $ALL. It performs the same function as the keyword and value pair EXCLUDE <database>. If both variables are used, they augment each other to determine which databases to exclude.
