What does backlog mean in this context? 'You could be in a determined mood to do battle with the back log of paperwork which is good'

Sounds like it's from a horoscope...

Means that you will be in that sort of mood where you will deal with paperwork (which could be anything from work related to university to household bills) that has built up and should have already been dealt with

"should have already been dealt with" but since you are such abusy lady ..you just have not had the time --- yet

In this context, think of log like a queue. So, it's saying you have a back queue of things.

You commonly hear the phrase, "I'm so back logged right now, I can't get to that."

Or, "They take forever to process those reports because they have such a back log"

"Backlog of paperwork". All the stuff (paperwork), that has built up while you were away, or not paying attention, or for whatever reason, that is now demanding your attention.

or...Google is your friend...Backlog generally refers to an accumulation over time of work waiting to be done or orders to be fulfilled.

Thanks everyone
