How QCSB Transfers Between Local and Remote Providers

This article explains the controlled temporary staging used when required for Local↔remote and remote↔remote operations, keeping provider-specific credentials isolated while data crosses connectors.

What you need to know

  • Basic includes Local storage and the first active Workspace. Pro adds FTP/SFTP, multiple Workspaces, advanced permissions, and background continuation. Max/All Access adds Google Drive, OneDrive, Private Connections, Recovery Vault management, and bulk operations.
  • A plan gate decides whether a feature exists at the current Effective tier. Joomla access and QCSB permission rules separately decide whether a particular user may use that feature.
  • QCSB uses durable jobs but follows an immediate-first model: the request attempts ordinary work immediately, and only unfinished work remains for continuation.
  • Pro/Max/All Access can use the 5-minute Transfer Continuation task. The worker rechecks the original user’s current authority before contacting a provider.

Provider-neutral transfer boundary

  • QCSB resolves the selected source through its provider service and resolves the destination through its own provider service; the user does not receive either side’s credentials.
  • The source and destination exact roots are enforced independently.
  • Conflict handling is applied at the destination before QCSB finalizes a write.
  • For Move, destination verification and Recovery protection occur before source removal.
  • A transfer can therefore cross Local, FTP, SFTP, Google Drive, or OneDrive as supported by the current Effective tier and each side’s permissions without treating the providers as one merged filesystem.

Verify the result

  • The durable job reaches the expected terminal state: completed, completed with warnings, failed, or cancelled.
  • Successful items remain successful; failed/retried items report their own sanitized outcome.
  • For a Move, the source is removed only after the destination is verified and the source has required Recovery protection.

Troubleshooting

  • If the provider is unreachable, test the connection in Administrator before troubleshooting the Workspace UI.
