Background Scrub Engine
Periodic Scrubbing of Stored Data Against Bit Rot
Background scrubbing engine periodically reading all stored data, refreshing ECC, and detecting bit rot before it accumulates beyond correction.
Purpose
Background scrubbing engine periodically reading all stored data, refreshing ECC, and detecting bit rot before it accumulates beyond correction.
Context
Child of L2-DVT-INTEG within the Lunar Ark system
Principles
- ▸Periodic scrub interval based on cell aging
- ▸ECC refresh on every scrub
- ▸Bit-rot statistics tracked over time
- ▸Alerts when error rate increases
- ▸Coordinated with L3-DVT-DIGI-CTRL
Typical implementations
- ▸Spacecraft memory scrubbing heritage
- ▸Data center scrubbing (terrestrial)
- ▸ECC monitoring practice
Lunar considerations
- ▸Long-mission essential for digital storage
- ▸Power-managed scrub schedule
- ▸Telemetry to L1-CDH
