Network Traffic Report

Published : September 27, 2005

The first page of the Network Traffic Report, the summary page, shows network traffic statistics for all file servers or protection groups at a file server or protection group level, as specified in the report parameters. Figure 3.1 shows the information contained in the traffic summary.

The report also includes the average weekly data change rate for the top 10 file servers or protection groups. The weekly data change rate is the ratio of the size of synchronization data being transferred to the size of the data (or volume) being protected, expressed as a percentage.

Based on sample measurements, an average daily change rate of more than 10% is high and can lead to synchronization failures. If the data change rate is high, make sure that there is enough disk space in the synchronization log on the file server to track data changes. As a precautionary measure, you can also enable nearly-continuous synchronization, if you are not already doing so.
