Test methodology

  • We performed three complete data backups of the SAP HANA database on a Dell EMC Ready Node and a Ready Solution Scale-out. Our expectations were as follows:

    • First backup―Data in the first backup is 100 percent unique and therefore deduplication is minimal. We expect the first complete data backup to use the most network throughput, have the longest backup duration, and the smallest backup compression ratio. The test engineers increase the SAP HANA database by 3 to 4 percent of unique data after each backup.
    • Second backup― We expect the second complete data backup to show the value of using DDBEA client-side deduplication by lowering the network throughput and backup duration. The client-side deduplication is also expected to increase our compression savings, meaning that our total compression increases.
    • Third backup―We expect the third and final backup to have a backup duration time that is similar to the second backup because the data growth is similar. We expect the total compression ratio to significantly increase because of the client-side deduplication savings.
