Data archiving vs data storage
Short answer
Data storage holds active, frequently accessed data on fast media like SSDs for daily use. Data archiving preserves rarely accessed, fixed data on low-cost media like tape for long-term retention and compliance.
Compare and contrast the terms data archiving and data storage.
| Point | Data storage | Data archiving |
|---|---|---|
| Purpose | Keep current, active data available for daily use and processing | Keep old, rarely used data for the long term (history, legal, backup) |
| Access | Fast and frequent (online) | Slow and rare (offline or nearline) |
| Data | Working data that changes | Fixed data, usually not modified |
| Media | Hard disk, SSD, RAM, flash | Tape, optical disc, cold cloud storage |
| Cost per GB | Higher | Lower |
| Retention | Short to medium term | Many years, with compliance rules |
| Management | Backed up often | Indexed, compressed, protected against ageing |
| Example | Logger memory, database | Sensor logs from previous years kept on tape |
Storage is for operation; archiving is for preservation.
