Below is a using three complementary layers. Layer 1: RAID (Real-time Redundancy) Protects against immediate drive failure without downtime.
| RAID Level | How it works | Tolerates | Use case | |------------|--------------|-----------|----------| | RAID 1 | Mirroring | 1 drive failure | OS, small critical data | | RAID 5 | Striping + parity | 1 drive failure | General storage (3+ drives) | | RAID 6 | Striping + dual parity | 2 drive failures | Large media, high safety | | RAID 10 | Mirrored stripes | 1–2 drives | Databases, high I/O | create redundant data recovery mechanism
Why this matters: Hard drives fail. Ransomware hits. Data gets corrupted. If your data exists in only one place (or even one type of place), it’s at risk. A redundant recovery mechanism ensures you can restore data even after multiple failures. Below is a using three complementary layers
Build yours this weekend. You’ll thank yourself when disaster strikes. Ransomware hits
