The IsSet operator in queries
In a query, you can use the IsSet operator to ensure that certain virtual machines are included or excluded from the backup.
For example: You can use IsSet to exclude virtual machines from the backup list that do not have any Notes associated with them.
Table: Examples of queries with the IsSet operator
Query rules with IsSet operator | Effect of the query on virtual machine selection |
|---|---|
Displayname Contains "prod" AND Notes IsSet | INCLUDED: Any virtual machine with a display name that contains the string "prod" if the virtual machine also has Notes. EXCLUDED: Any virtual machines that do not have Notes. Without Notes IsSet in this query, virtual machines without Notes cannot be excluded. |
Cluster Contains "dev" AND Notes IsSet | INCLUDED: Any virtual machine in a cluster that has a name that contains the string "dev" if the virtual machine also has Notes. EXCLUDED: Any virtual machines that do not have Notes, and any virtual machines that have Notes but that are not in a cluster that has a name that contains "dev". Without Notes in this query, virtual machines without Notes cannot be excluded. |
The policy's Primary VM identifier parameter has an important effect on which virtual machines NetBackup can back up. This parameter affects the test query results.
