How Temporary QCUL Production Checkpoints Work

A temporary QCUL production checkpoint is a private, operation-scoped snapshot of the live update-related file/database scope created immediately before a selected push.

Checkpoint design

• Stored privately and tied to the run/replay operation.
• Created only when the administrator chooses temporary QCUL protection.
• Captures database definitions, indexes/foreign keys, row data, protected file hashes, and created-file removal information needed for rollback.
• Built in restartable batches and validated before the production installer begins.

Short-lived by design

Its purpose is fast rollback of one update during the configured Undo Production Push window. It is deleted at expiry or with laboratory removal and is not meant to become a long-term backup archive.

Independent backup still required

A full backup/recovery product protects broader disasters and history. Keep that separate recovery layer even when QCUL’s temporary checkpoint is selected.

Recovery discipline

When working with How Temporary QCUL Production Checkpoints Work, 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.
