Long-term backup retention (LTR) for Azure SQL Managed Instance in public preview
发布日期：三月 17, 2021
Many applications have regulatory, compliance, or other business purposes that require you to retain database backups beyond the 35 days provided by Azure SQL Managed Instance automatic backups. When using the LTR feature, you can automatically retain specified SQL Managed Instance full backups in separate Azure Blob storage with configured redundancy for up to 10 years. You can then restore any backups as a new database. LTR may be configured on both single and pooled instances.
