As expected, the first full data backup of the SAP HANA database required the most network throughput, as Figure 5 shows. The first backup consisted of unique data. Therefore almost the entire database was transferred over the network to the DD 6300 system. We included the backup duration times in the graph to show the relationship between network throughput and backup times. In this case, the first backup used on average 507 MB/s to protect a 1.3 TB database in 36.8 minutes.

The following figure shows the network throughput with the backup duration times.

The first backup shows tthat Data Domain can back up large new data sets very quickly. Because IT organizations commonly provision new databases on-demand, they must have the agility to protect the new environments quickly.

The second and third backups show the bandwidth reduction value of DDBEA client-side deduplication. For the second backup, the network throughput falls to 109 MB/s and the backup duration falls to 12 minutes. For the third and final backup, the network throughput is 80 MB/s and the backup time is 12.7 minutes. The second and third backups use only 20 percent (5X reduction) of the network throughput of the first backup. The network throughput savings enable the IT organization to back up more databases in parallel.
