Resuming an Interrupted Production Rollback

A production rollback that stops after an error is intentionally resumable: QCUL saves the current database/file cursor and refuses to loop forever without administrator intervention.

Step-by-step procedure

1. Open the active tested-update row showing rollback attention.
2. Read the saved attention message and correct the underlying filesystem/database/resource issue.
3. Select Resume Undo or the displayed Resume Rollback action.
4. QCUL continues from the saved database/file cursor instead of repeating completed restore work.
5. Verify version, routes, and protected hashes after rollback finishes.

Why resume is safer than restart

Restarting from the beginning can collide with already restored database/file state. Resume continues the known checkpoint operation from persisted progress and keeps its verification/report chain intact.

When to stop and escalate

If the same rollback step repeatedly fails after the underlying permission/storage issue is corrected, preserve the report/error and use your independent full-site recovery method or private support rather than manually mixing old/new database and files while QCUL still reports an incomplete rollback.

Recovery discipline

When working with Resuming an Interrupted Production Rollback, keep the independent backup available even if the QCUL checkpoint is valid. The checkpoint is a fast, short-lived update rollback mechanism; if its protected scope, validity window, or verification cannot satisfy the incident, move to the broader recovery plan rather than extending QCUL beyond its promise.
