About the Reuse VM selection query results option
The Test query screen lists the virtual machines that NetBackup discovered in your KVM environment. Because the automatic selection feature is dynamic, later changes in the environment may affect which virtual machines match the query rules. For example: if virtual machines are added later, the current test results may not be identical to the virtual machines that are selected when the backup runs.
During the period you specify on Reuse VM selection query results for, NetBackup reuses the current list of virtual machines as the backup list. It does not consult the Query builder or rediscover virtual machines.
Note the following about the option:
It determines how long the query results are reused.
It has no effect on when the NetBackup policy schedule runs.
The option is invalidated if the query rules are changed or if the policy attributes that affect discovery are changed. In that case, NetBackup rediscovers virtual machines the next time the policy runs.
For example: assume that the option is set to 8 hours and your query selects turned-on virtual machines. If additional virtual machines are turned on during the 8-hour period, they are not added to the policy's backup list. The policy backs up the virtual machines that were last added to the list (such as when the policy was created). After 8 hours, when the policy runs next, the recently turned-on virtual machines are discovered and added to the backup list.
Assume that the next backup occurs before the period expires and a virtual machine was renamed during the Reuse period. Then NetBackup backs up the renamed virtual machine under its original name. Because the reuse period has not expired, NetBackup does not rediscover virtual machines and therefore cannot identify the virtual machine by its new name. (NetBackup identifies the virtual machine by its instance UUID.) To have backed up the virtual machine with its new name, the period should have been set to a shorter interval and the discovery process should have been initiated.
Note: The virtual machines that are selected for backup are not displayed on the policy Backup selections tab. To see which virtual machines NetBackup has selected and backed up, refer to the following topic.
