質問 # 33
Why bakcup storage capacity is larger than production storage is that backup storage stores multiple copies of production data...
- A. False
- B. True
正解：A
解説：
Explanation
The reason why backup storage capacity is larger than production storage is not that backup storage stores multiple copies of production data, but that backup storage stores multipleversions of production data. Backup storage provides data protection for production data by creating backup images at different points in time.
These backup images can be used to restore production data in case of any data loss or corruption. Backup storage usually stores more versions of production data than production storage itself, which makes backup storage capacity larger than production storage capacity.
