Cumulative Replication Statistics

50
The Data Reduction Statistics area displays the following information:
• Total Data Reduced - The original, native size of all existing data
that has been processed by the data deduplication and compression
engines.
• Total Reduction Ratio - The total reduction ratio of all existing data
that has been processed by the data deduplication and compression
engines (Total Data Reduced by Reduced Size).
• Reduced Size - The final, reduced size of all existing data that has
been processed by the data deduplication and compression engines.
Note: Because these values are calculated as data is deduplicated and
compressed, they will not be completely up-to-date until all
data that is eligible for deduplication is processed by the data
deduplication and compression engines.
The Cumulative Replication Statistics area displays the following
information:
• Total Data Sent - The original, native size of the data transferred
during replication or failback. This value does not indicate the
amount of bytes that actually crossed the network during
replication or failback.
• Total Bytes Sent, Total Bytes Received - The number of bytes
actually transferred over the network during replication or failback.
These values are usually much less than the native size due to the
benefits of data deduplication.
• Average Send Rate, Average Receive Rate - The average number
of bytes actually transferred over the network during replication or
failback. These values are calculated as the total number of bytes
