Deduplication > Deduplication Size Factor

This report is usually the most talked about when it comes to deduplication since it shows what the deduplication ratio is for each day over the last two weeks (the time frame is modifiable). The deduplication ratio is calculated by taking the total number of bytes that would normally be backed up and dividing it by the number of bytes that have changed and were backed up. So if 100TB exists on all the backups taking place but only 10TB were changed and therefore transferred, you have a rate of 10. This report shows only deduplication jobs. The default Report On parameter for this report is Master Server. This report is available in a line-chart format.

This report is available in historical and ranking views. The ranking report ranks the top hosts in terms of which ones have the best deduplication ratio in bytes. These hosts have the least amount of change and therefore you get the best benefit from deduplication.
