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.ย
For example, evaluate asset A with the backup policy โDaily RPO 14 day retention, Monthly RPO 3 month retentionโ. 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 โDaily RPO 30 day retentionโ. The total recovery points will be 30.ย 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 ofย โDaily RPO 30 day retentionโ.
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%
