Background Transfer Continuation on Pro, Max, and All Access

This article explains the Pro+ background-continuation feature and its 5-minute Scheduled Task, including how it resumes unfinished durable jobs after the immediate request ends.

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.

Continuation requirements

  • The current Effective tier must include Pro-or-higher background continuation.
  • The canonical QC Storage Bridge Transfer Continuation Scheduled Task must exist, be enabled, and run every 5 minutes.
  • There must be unfinished eligible durable job items; completed work is not needlessly replayed.
  • The worker rechecks the original user’s current authorization before provider access, so losing access can stop later continuation.
  • Server cron is preferred on low-traffic sites so continuation is not delayed waiting for frontend traffic.

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.
