Ready Node for SAP HANA test results

Backup duration findings

  • Because DDBEA had to back up the entire database of unique data, the first full data backup had the longest duration at 36.8 minutes. DDBEA cannot perform client-side deduplication on the initial backup because there is no data for comparison on the backup appliance.

    The following figure shows the backup duration times for all three backups that were performed in this test.

    Figure 4.         Ready Node for SAP HANA backup duration times

    The second and third backups show the benefit of the client-side deduplication. The second backup took 12 minutes and the third backup took 12.7 minutes. The backup durations were similar because the data growth of 3 to 4 percent after each backup meant that the amount of unique data was similar. DDBEA was able to identify all the previously protected blocks, providing a time savings that was three times greater than the first full data backup.
