If multiple messages reference the same backup file at once, they now share a single copy operation instead of each triggering a redundant copy.\n\n**Why**\n\nThis avoids unnecessary duplicate work when restoring a resumed session, which is more efficient and reduces the chance of conflicting concurrent copies of the same backup file.\n\n- Area: Elsewhere\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5"}
