# Redis Persistence: What is the difference between RDB and AOF?

Redis provides two primary persistence mechanisms: **RDB snapshots** and **Append Only File** (AOF). Choosing between them depends on your application's write volume, recoverability requirements, and performance overhead tolerance.

## RDB vs AOF Comparison

- **RDB (Redis Database)**: Performs point-in-time snapshot saves of your dataset at specified intervals. Ideal for backups and fast restarts.
- **AOF (Append Only File)**: Logs every single write command received by the server. Provides highest data durability.

The code snippet below shows how to query and toggle AOF settings using Python:

```python
import redis

# Establish Redis connection
r = redis.Redis(host='localhost', port=6379, db=0)

# Dynamically enable AOF persistence
r.config_set('appendonly', 'yes')

# Set fsync strategy to sync every second
r.config_set('appendfsync', 'everysec')

# Query active configuration state
aof_enabled = r.config_get('appendonly')
print(f"Append Only Enabled Status: {aof_enabled}")
```
