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.

See Effect of Primary VM identifier parameter on Selection column in Test Query results.
