İş Sürekliliği Planlaması
Platform, felaket durumlarında iş sürekliliğini sağlamak için kapsamlı DR stratejileri sunar.
**DR Objectives:**
**RPO (Recovery Point Objective):**
Maksimum kabul edilebilir veri kaybı:
- Standard: 1 saat
- Enhanced: 15 dakika
- Real-time: <1 dakika
**RTO (Recovery Time Objective):**
Maksimum kabul edilebilir kesinti:
- Standard: 4 saat
- Enhanced: 1 saat
- Real-time: 15 dakika
**DR Tiers:**
**Tier 1 (Cold):**
- Daily backups
- Manual recovery
- Hours to restore
- Lowest cost
**Tier 2 (Warm):**
- Hourly replication
- Standby environment
- 1-4 hours to restore
- Moderate cost
**Tier 3 (Hot):**
- Real-time replication
- Active-passive
- Minutes to restore
- Higher cost
**Tier 4 (Active-Active):**
- Multi-region active
- Auto-failover
- Near-zero downtime
- Highest cost
**Planning:**
**BIA (Business Impact Analysis):**
- Critical systems identification
- Downtime cost analysis
- Priority ranking
**DR Plan:**
- Procedures documented
- Roles and responsibilities
- Communication plan
- Testing schedule
Yedekleme ve Replikasyon
Veri koruma için çok katmanlı yedekleme ve replikasyon stratejileri.
**Backup Strategy:**
**Types:**
**Full Backup:**
- Complete copy
- Weekly schedule
- Longer to create
- Faster restore
**Incremental:**
- Changes since last backup
- Daily schedule
- Fast creation
- Longer restore
**Differential:**
- Changes since last full
- Balance approach
- Moderate both
**3-2-1 Rule:**
- 3 copies of data
- 2 different media types
- 1 offsite location
**Replication:**
**Synchronous:**
- Real-time copy
- Zero data loss
- Same region recommended
- Latency impact
**Asynchronous:**
- Near-real-time
- Minutes of lag
- Cross-region suitable
- Minimal impact
**Destinations:**
**Cloud:**
- AWS S3/Glacier
- Azure Blob
- Google Cloud Storage
- Cross-region
**On-Premise:**
- Secondary datacenter
- Tape library
- NAS/SAN
**Backup Management:**
**Scheduling:**
- Automated backups
- Configurable windows
- Resource throttling
**Retention:**
- Daily: 30 days
- Weekly: 12 weeks
- Monthly: 12 months
- Yearly: 7 years
**Verification:**
- Automated test restores
- Integrity checks
- Alert on failure
Failover ve Kurtarma Prosedürleri
Felaket durumunda hızlı failover ve sistemlerin kurtarılması.
**Failover Types:**
**Automatic:**
- Health check failure
- Immediate failover
- No manual intervention
- DNS-based or load balancer
**Manual:**
- Deliberate decision
- Planned maintenance
- Controlled switch
- Verification steps
**Failover Process:**
**Detection (Automatic):**
1. Health check fails
2. Retry (3 attempts)
3. Declare failure
4. Initiate failover
**Switchover:**
1. Stop writes to primary
2. Ensure replication caught up
3. Promote secondary
4. Update DNS/routing
5. Verify services
6. Resume operations
**Failback:**
1. Primary restored
2. Resync data
3. Validate integrity
4. Planned switchback
5. Return to normal
**Recovery Procedures:**
**Data Recovery:**
```
1. Identify failure point
2. Select appropriate backup
3. Restore to staging
4. Validate data
5. Cutover when ready
```
**System Recovery:**
```
1. Provision infrastructure
2. Deploy application
3. Restore configuration
4. Restore data
5. Test functionality
6. Update routing
```
**Testing:**
**DR Drills:**
- Quarterly full test
- Monthly partial test
- Documented results
- Continuous improvement
**Test Types:**
- Tabletop exercise
- Simulation
- Partial failover
- Full failover test
**Documentation:**
- Runbooks
- Contact lists
- Escalation paths
- Vendor contacts
