Auto-Verify is enabled on a per-unit basis, and works in conjunction with the Verify Schedule, which is set on a controller-wide basis. Two verify schedules settings are available (Basic and Advanced), and Auto-Verify works differently, depending on which is selected.

The Basic Verify schedule (enabled, by default), provides a weekly day and time for Auto-Verify to occur. When the Basic schedule is used, Auto-Verify will start a verify at the designated time, and run until it has finished.

For users who need more control over when Verify tasks run, an Advanced Verify schedule is also available, which gives you the ability to define seven times during the week when verifications can occur, and allows you to specify the duration of each, effectively creating a series of "schedule windows". This is useful if you want to insure that background tasks such as verification occur during times of low system usage. When you use the Advanced Verify schedule, if a verify does not have time to complete during a scheduled time window, it will pause until the next scheduled time, to resume verifying.

This distinction between Basic and Advanced Verify Scheduling is new in 9.5.1. In previous versions, there was one type of Verify Scheduling, which functioned as the "Advanced" version does in 9.5.1.
