CONCLUSION:

================================================================================
|
||||
|
||||
✅ DR RESTORE CAPABILITY: VERIFIED
|
||||
✅ Backup-urile de pe DR server pot fi restaurate cu SUCCESS
|
||||
✅ Database poate fi deschis și accesat
|
||||
✅ RTO se încadrează în target-ul stabilit (45-75 min)
|
||||
|
||||
RECOMANDĂRI:
|
||||
- Rulează acest test LUNAR (prima Duminică a lunii)
|
||||
- Monitorizează RTO și optimizează dacă crește
|
||||
- Verifică că backup-urile noi sunt transferate corect
