Data Maintenance: Keep Your Information Asset Valuable

Building a data warehouse is a sprint; maintaining it is a marathon. "Data Maintenance" is the set of ongoing activities that ensures your data environment remains secure, accessible, and performant over time.

The Four Pillars of Data Maintenance

1. Security & Access Control: As employees leave and join, permissions must be updated immediately. Stale accounts are a primary vector for cyberattacks.
2. Performance Tuning: As data volume grows, queries that took 2 seconds might take 2 minutes. Regular indexing and partitioning are required to keep dashboards snappy.
3. Backups & Disaster Recovery: The rule of 3-2-1: 3 copies of data, 2 different media, 1 offsite. Automated daily backups are non-negotiable.
4. Archiving: Not all data needs to be "hot." Moving 5-year-old transaction logs to cheaper "cold" storage saves money while keeping the active warehouse fast.

Proactive vs. Reactive

Reactive maintenance is fixing the database after it crashes. Proactive maintenance is monitoring disk usage trends to upgrade storage before it fills up. At Hawkeye Core, we believe proactive maintenance is the only way to run a serious data operation.
