Data Recovery score

The Data Recovery 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 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.


Asset	Asset size (GB)	Available recovery points	Backup score( available recovery points/ total expected recovery points)	Weighted score in GB (Asset size x Backup score)
1	120	12	70%	84
2	60	16	94%	56.4
3	30	8	47%	14.1
	Total assets = 210 GB			Total weighted score in GB = 154.5
				Data Recovery score = 154.5/210 = 73.57%

The Data Recovery score for all assets is 73.57%

Data Recovery 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 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”.


Asset	Available recovery points	Backup score( available recovery points/ total expected recovery points)	Count based score
1	20	66%	0.66
2	9	30%	0.3
3	28	93%	0.93
			Total score = 1.89
Total assets count = 3			Data Recovery score = 1.89/3 = 63%

The Data Recovery score for all assets is 63%
