What QC Update Laboratory Does Not Do

QCUL is an update-rehearsal and operation-scoped rollback tool; it is deliberately not a general staging, backup, disaster-recovery, or whole-site deployment platform.

Current boundaries

  • It does not maintain a permanent two-way staging environment.
  • It does not copy the entire laboratory database/site back over production.
  • It does not replace an independently restorable backup or recovery plan.
  • It does not certify every page, payment provider, webhook, role, or third-party integration merely because automated checks passed.
  • It is not a multi-site agency control panel, DNS automation system, firewall, or hosting-management suite.
  • Its temporary production checkpoint is operation-scoped and short-lived, not a general backup archive.

Why the boundaries matter

QCUL intentionally ties one test, one exact package, one evidence record, and one production decision together. That narrow scope makes the production decision auditable and lets rollback protect the update-related scope without pretending to be a replacement for full-site disaster recovery.

Keep an external backup

Before any production push, maintain a complete, independently restorable backup. Even when you choose the temporary QCUL rollback checkpoint, that checkpoint should be treated as a fast undo path for the selected update—not as the only recovery copy of the site.

Practical administration note

For What QC Update Laboratory Does Not Do, make changes from the live Joomla administrator and verify the result in the same QCUL tab before starting laboratory work. QCUL’s streamlined 1.01.14 interface intentionally hides developer storage paths, raw batch controls, licensing fields, and retired management screens; do not look for those older controls as part of the current procedure.
