Which is the correct formula for calculating the file system backup bandwidth?

• A.If replication is required, the formula is as follows: Required bandwidth (with deduplication) = Amount of data to be replicated -r Backup window -r Bandwidth utilization rate.
• B.If replication is not required, the formula is as follows: Required bandwidth (without deduplication) = Data amount of full backup -f Backup window -r Bandwidth utilization rate.
• C.If replication is not required, the formula is as follows: Required bandwidth (with deduplication at the media end) = Data amount of full backup -r Deduplication ratio -r Backup window -f Bandwidth utilization rate.
• D.If replication is not required, the formula is as follows: Required bandwidth (with client deduplication) = Data amount of full backup -=- Backup window -f Bandwidth utilization rate.
