Streaming and mirroring are two ways to use My Drive through Google Drive for desktop. Choose according to local capacity, offline needs, and application behavior. Both synchronize changes, so neither mode should be described as an independent historical backup.
Compare storage and availability
Streaming keeps files primarily in the cloud and downloads content when needed or marked for offline use. It reduces ordinary local storage needs, but cached and offline files still occupy disk space.
Mirroring keeps a local My Drive copy as well as the cloud version. It needs enough local capacity and can suit workflows that regularly use ordinary files without a connection. Native Google documents need the separate browser offline setup for offline editing.
Check the location and platform
Shared drives support streaming rather than My Drive-style mirroring. Computer folders added for synchronization use a different arrangement. Do not assume one My Drive mode setting changes every location shown by the app.
Recent macOS File Provider behavior differs from traditional Windows or legacy Mac streaming, including access to already downloaded files when the app is closed. Use the platform-specific guidance for your actual setup.
Choose and verify deliberately
Before changing modes, finish synchronization and preserve any local-only edits. Review the selected local folder and available capacity, then use Drive’s supported preferences rather than moving internal locations manually. Verify the active path and representative cloud contents afterward. A mode change can leave an old local folder that no longer syncs, or download a large amount of content. Keep that distinction clear before deleting anything. If your organization manages the setting, ask the administrator for an approved configuration rather than overriding its device policy.
