Chapter 6: Testing and Validation
The charts below show the same database backup cycle but in this case, the backup
schedule employed a mix of both Level 0 full and Level 1 (incremental) backup.

Line 1: “Data Written” is much lower in this instance as the backup schedule
employed incremental backups during the week; therefore much less data was sent
to the appliance, approximately 10 TB.
Line 2: “Data Stored” remains the same, however, as the Data Domain appliance
identifies and saves only the unique data sent to the appliance. This reduces the
overall data reduction as less redundant data is sent to the appliance.
Line 3: "% Reduction" shows the storage saving as a percentage over the five-week
period.
