Logging data from a calculate field of a report

You would need to make a table called backlog today with a single record in it.  it will be [Record ID#] of 1.

Then on the projects table make a new field called [Link to backlog (=10] with a formula numeric formula of 1.

Then make a Relationship where 1 Today's Backlog has many projects based on that link field.

Then make a summary field of the backlog.

If you get that far I will help you with the button.
