I just finished backfilling mine in that exact same situation. I didn't do the french drain, as suggested above, but my yard has a good slope and I don't think it will be an issue in the end. If I see any issues, I may add the drain later to help route any water around it.
For what it's worth... My installer told me it wouldn't be an issue to back fill. I think the warranty even allows backfill up to 2 ft(probably depends on pool). I was skeptical of believing just him though, so I researched online and found it to be mostly a non-issue. The only thing people suggest is to make sure the water drains around the pool and doesn't sit against it or wash under.
Heck, there's people that fully bury above ground pools...
