Furthermore, because Exagrid uses a "Landing Zone" approach, if ransomware hits during a backup window, it only affects the current backup being written. The deduplicated repository (holding your historical data) is segmented and locked down.
One of ExaGrid's most critical features today is its Retention Time-Lock for Ransomware Recovery . This feature creates a "non-network-facing" tier (an air gap) where backup data is stored. Even if a ransomware attack encrypts your primary data and your live backup tier, the data in the Retention Tier remains immutable and can be used for a clean recovery. 2. Scale-Out Architecture exagrid
The traditional approach to backup often involves backing up data directly to a deduplication appliance. While this saves space, it creates a "performance bottleneck" because the data must be processed and "rehydrated" every time you want to restore it. ExaGrid solves this through its unique two-tiered approach: Furthermore, because Exagrid uses a "Landing Zone" approach,
The system monitors for hardware failures (e.g., failed disk drives) or communication issues. ExaGrid Support Engineers often proactively contact customers if these alerts indicate a potential problem. This feature creates a "non-network-facing" tier (an air
| Feature | ExaGrid | Inline Dedupe Appliances (e.g., Data Domain) | |---------|---------|-----------------------------------------------| | | Very fast (no inline calc) | Slower (compute during ingest) | | Restore speed | Very fast (hydrated landing zone) | Slow (rehydration required) | | VM boot from backup | Instant (full copy exists) | Slow (must rehydrate first) | | Scale-out | Linear (add nodes = add performance) | Often requires rebalancing or complex expansion | | Deduplication ratio | High (global) | High (but often inline) |
