### 1. Automated S3 Backup Bash Script (`/usr/local/bin/db-backup.sh`) 💾

```bash
#!/bin/bash
TIMESTAMP=$(date +"%Y%m%d_%H%M%S")
BACKUP_DIR="/tmp/db_backups"
BUCKET_NAME="s3://boost-engine-db-backups-872515272656-ap-south-1-an"

mkdir -p $BACKUP_DIR

# 1. Dump MySQL Database:
mysqldump -u root -p"$DB_PASS" rishabh_kaksha | gzip > $BACKUP_DIR/db_$TIMESTAMP.sql.gz

# 2. Stream to AWS S3 Cloud Storage:
aws s3 cp $BACKUP_DIR/db_$TIMESTAMP.sql.gz $BUCKET_NAME/mysql/

# 3. Cleanup local temp files:
rm -rf $BACKUP_DIR
```

---

### 2. Cron Job Scheduling (`crontab -e`)

```cron
# Run daily automated cloud backup at 2:00 AM UTC:
0 2 * * * /usr/local/bin/db-backup.sh >> /var/log/backup.log 2>&1
```

### 3. Interview Ke 3 Sawal Is Topic Se

1. **Cloudflare R2 AWS S3 se cost perspective se kyu better hai?** -> Zero Egress bandwidth fees! (Data download par koi charge nahi lagta).
2. **S3 Lifecycle Rules backup management me kaise use hoti hain?** -> 30 din purane daily backups ko automatic S3 Glacier Deep Archive me move karna ya 90 din baad auto-expire karna.
3. **Backup restoration drill regular intervals par kyu zaroori hai?** -> Taaki verify ho sake ki corrupted dump files nahi hain aur disaster recovery time (RTO) SLA ke andar hai.
