Need for backups?

Say we have a PFS replicated from Prod to DR and we are taking snapshots on both sides.

What prevents us from eliminating backups? What are the failure scenarios?

Thanks!

It doesn't protect you from the scenario where data gets corrupted before it is replciated, as described in this thread:

Also, your snapshots are all pointing to the original file system. If something happens to the original file system, you cannot recover from the snapshots.
