The basics of a NetBackup query rule
For automatic virtual machine selection, NetBackup uses query rules to determine which Hyper-V virtual machines to select for backup. You create the rules in the Query builder, on the Clients tab of the policy.
A query rule consists of the following:
A keyword, such as Displayname (many keywords are available).
For example: For automatic selection of the virtual machines with the display names that contain certain characters, you need the Displayname keyword in the rule.
An operator, such as Contains, StartsWith, or Equal.
The operator describes how NetBackup analyzes the keyword. For example: Displayname StartsWith tells NetBackup to look for the display names that start with particular characters.
Values for the keyword.
For the Displayname keyword, a value might be "prod". In that case, NetBackup looks for the virtual machines that have the display names that include the characters prod.
An optional joining element (AND, AND NOT, OR, OR NOT) to refine or expand the query.
The policy uses these elements to discover and select virtual machines for backup.
