Hey @Tom Evans , great question.
We kind of have 2 questions here:
- How is Extended Retention applied?
- How can I schedule a backup on the last day of the month?
The first one (which you might already be aware of, though I answer to give a complete picture) is that Extended Retention is going to apply (in this case) to the last full of a given month (or the mopst recent in the current month). Whether it runs as part of a plan, or schedule, or was manually kicked off, the operation simply looks at the fulls like an inventory and applies your extended retention to the last one that completed, period.
With that said, I do not see any option to configure a Plan in Command Center to run on the last of the month (but you can do this in the Commcell Console).
I’ll ask around to see if this is something that has to be done in the console or if Command Center is an option.
