# Local and remote vaults

Obsidian saves your notes in a local vault on your computer or device. A local vault is simply a folder that holds your notes.

If you want to use your notes on different devices, you need to share your local vault with those devices.

Obsidian Sync is one solution that helps you do this by connecting your local vault to a remote vault. A remote vault is a copy of your vault stored on Obsidian's servers.

You can connect one or more local vaults on your devices to a remote vault. When you make changes to a local vault, the changes are saved to the remote vault. Then, the updated content is synced to all other local vaults connected to the same remote vault.
