Limitations of Azure Arc-enabled SQL Managed Instance

  • Article

This article describes limitations of Azure Arc-enabled SQL Managed Instance.

Back up and restore

Automated backups

  • User databases with SIMPLE recovery model are not backed up.
  • System database model is not backed up in order to prevent interference with creation/deletion of database. The database gets locked when admin operations are performed.

Point-in-time restore (PITR)

  • Doesn't support restore from one Azure Arc-enabled SQL Managed Instance to another Azure Arc-enabled SQL Managed Instance. The database can only be restored to the same Arc-enabled SQL Managed Instance where the backups were created.
  • Renaming databases is currently not supported, during point in time restore.
  • No support for restoring a TDE enabled database currently.
  • A deleted database cannot be restored currently.

Other limitations

  • Transactional replication is currently not supported.
  • Log shipping is currently blocked.
  • All user databases need to be in a full recovery model because they participate in an always-on-availability group

Roles and responsibilities

The roles and responsibilities between Microsoft and its customers differ between Azure PaaS services (Platform As A Service) and Azure hybrid (like Azure Arc-enabled SQL Managed Instance).
