The retention policy for the forward incremental backup chain is calculated by the following formula:
Retention period = MAX (Catalog Retention, X)
- Catalog Retention is the retention period specified in Veeam Backup Enterprise Manager.
- X is the amount of time for which restore points are kept by a backup jobs.
For example, the retention policy settings are specified in the following manner:
- The retention policy for a backup job is set to 5 points. The backup job is run daily.
- The retention period in Veeam Backup Enterprise Manager is set to 1 month, or 30 days.
In this case, Veeam Backup Enterprise Manager will retain indexing data for 30 days, because this value is greater than the number of restore points in the job.
