+ ### Long-term retention
+
+ Azure Backup and Azure Database for PostgreSQL  server services have built an enterprise-class long-term backup solution for Azure Database for PostgreSQL single server instances that retains backups for up to 10 years. You can use long-term retention independently or in addition to the automated backup solution offered by Azure Database for PostgreSQL single server, which offers retention of up to 35 days. Automated backups are physical backups suited for operational recoveries, especially when you want to restore from the latest backups. Long-term backups help you with your compliance needs, are more granular, and are taken as logical backups using native pg_dump. In addition to long-term retention, the solution offers the following capabilities:
+
+Customer-controlled scheduled and on-demand backups at the individual database level.
+Central monitoring of all operations and jobs.
+Backups are stored in separate security and fault domains. If the source server or subscription is compromised, the backups remain safe in the Backup vault (in Azure Backup managed storage accounts).
+Using pg_dump allows greater flexibility in restoring data across different database versions.
+Azure backup vaults support immutability and soft delete (preview) features, protecting your data.
