Back up your game and recover from mistakes

Bricklayer is designed so mistakes are easy to undo. A real backup on top of that means you never have to worry.

Layer 1: Save a copy of the place

The simplest backup there is, and the one to make before you open an existing game in Bricklayer for the first time.

1. In Roblox Studio, choose File → Save to File As.
2. Save the .rbxl file in a backups folder, with the date in the name, like MyObby-2026-11-08.rbxl.

To restore, open that file in Studio.

Layer 2: Checkpoints

Run Bricklayer: Save a Checkpoint from the Command Palette before a risky change. Checkpoints give you a known-good point to return to without leaving the editor.

Layer 3: Undo and reject

• Every AI file change waits for approval, so the cheapest undo is Reject.
• Studio changes are undoable with Ctrl+Z.
• Approved file changes can be reverted in Bricklayer, or you can ask the AI to undo its last change.

See Review, approve, and undo AI changes.

Layer 4: Git (optional)

Your project is a normal folder, so Git works on it. If you already know Git, commit after every working feature and you can go back to any point. You do not need Git to use Bricklayer. Using your own tools.

Published games

Roblox keeps a version history for places you publish, which you can manage from the Creator Dashboard. It only covers what you published, so keep local backups too.
