Make backups portable to on-premise SQL
Get this message when attempting to restore an SMI backup to on-premise SQL:
The database was backed up on a server running version 15.00.0700. That version is incompatible with this server, which is running version xx.xx.xxxx. Either restore the database on a server that supports the backup, or use a backup that is compatible with this server.
Lock in is risky for customers for a number of reasons. A workaround is using BACPAC but getting an established database into a state where BACPAC doesn't spew errors is difficult in our experience.
Thanks for the feedback.
We assume that you are talking about ability to restore native backup (.bak files) taken from SQL MI to SQL Server 2017/2019.
It’s a tough one unfortunately. Native backup contains binary data, and never been backwards compatible. E.g. you can’t restore backup from SQL 2012 on SQL 2008. Same logic applies here.
SQL MI gets updates faster SQL Server, as soon we check-in code, it gets deployed with the next wave of updates on Azure. Same as SQL DB.
Theoretically if you take backup of SQL MI now, and wait until SQL Server version release catch up, then you will be able to restore it.
Can you please let us know what kind of issues with BACPAC you are encountering?
Also, you can consider making transaction replication from SQL MI on on-prem as a way to move data around.
