FSARunNow is perhaps a long forgotten about utility, but it's actually pretty hand in some situations. What does it do? Well, as the name suggests it runs an FSA 'task' or 'operation' now. This bypasses any schedule that might be defined and simply starts things going right now. That to me makes it quite handy.
You can run FSARunNow in a number of different modes, perhaps the simplest one is to get the utility to just run a simple pre-defined archiving task. To do that you would execute:
FSARUNNOW Archive "The name of the task that you see in the Vault Admin Console"
Simple, yet powerful!
