โดยทั่วไปเมื่อฉันเริ่มต้นในสภาพแวดล้อมใหม่ฉันมักจะตรวจสอบที่มีการสำรองข้อมูลเมื่อเต็มล่าสุดถูกนำมาใช้เมื่อมีการคืนค่าครั้งล่าสุดและฉันตรวจสอบความปลอดภัยด้วย
วิธีที่ฉันทำคือผ่าน T-SQL
ตรวจสอบข้อมูลสำรอง

นอกเหนือจากข้างต้นมีสิ่งอื่นใดอีกที่ฉันควรตรวจสอบเมื่อเริ่มต้นในสภาพแวดล้อมใหม่ตามลำดับความสำคัญ
