Retention Policy for Snapshots
For cloud-native snapshots, Veeam Backup for Microsoft Azure retains the number of latest restore points defined in backup scheduling settings.
During every successful backup session, Veeam Backup for Microsoft Azure creates a new restore point. If Veeam Backup for Microsoft Azure detects that the number of restore points in the snapshot chain exceeds the retention limit, it removes the earliest restore point from the chain. For more information on the snapshot deletion process, see Microsoft Docs.
Consider that Veeam Backup for Microsoft Azure does not apply retention policy settings to cloud-native snapshots created manually. To learn how to remove these snapshots, see sections Managing VM Data and Managing File Share Data.
