Dear user,
The answer is 72 MB.
1. To calculate the required network bandwidth, determine the following information:
a. Total amount of data (TD) to be replicated, in gigabytes.
b. Length of replication window time (RWT) in hours. The length of the replication window time is the time that you schedule during server maintenance for replication to occur.
c. Data deduplication ratio (DR), if you are using the data deduplication function. Issue the QUERY STGPOOL command and use the FORMAT=DETAIL value to determine the data deduplication ratio value. If you are not using the data deduplication function, use 100 as the data deduplication ratio value.
2. Calculate the bandwidth required by using the following formula:
(TD * (100 / DR) * 1024) / (RWT * 3600) = Required_Network_Bandwidth (MB/second)

TD=800 DR=80 RWT=4
Thanks.
