Data Recovery Protection Score

The Data Recovery Protection Score provides information on missing recovery points and how old the last backup is.

Data Recovery Score based on Asset Size (GB)

A size-based analysis of assets and backups shows the protection score for individual assets and the overall score for all assets being analyzed. 

For example, evaluate asset A with the backup policy “Daily RPO 14 day retention, Monthly RPO 3 month retention”. The total policy recovery points will be 17. If asset A has only 12 available recovery points, then the protection score is calculated:.

Data Recovery Protection Score of asset A: 12/17 = 70.58%

Aggregated score for assets- To find the aggregated score for all assets based on asset size, we calculate the score for individual assets and aggregate the scores to find the protection score. The table below shows how this is done.

Total assets = 210 GBTotal weighted score in GB = 154.5
Data Recovery Protection Score = 154.5/210 = 73.57%

The Data Recovery Protection Score for all assets is 73.57%

Data Recovery Protection Score based on Asset Count

When we perform a count-based analysis of assets and backups, we do not take into account the asset size. We calculate the score based on the number of expected and available recovery points.

For example, evaluate asset B with the backup policy “Daily RPO 30 day retention”. The total recovery points will be 30.  If asset B has only 15 available recovery points, then the protection score is calculated:

Data Recovery Protection Score of asset B = 15/30 = 50%

Aggregated score for assets- To find the aggregated score for all assets based on asset count, we calculate the score for individual assets and aggregate the scores to find the protection score. The table below shows how this is done for a backup policy of  “Daily RPO 30 day retention”.
