[!INCLUDEssHADR] can provide a high-availability and disaster recovery solution for [!INCLUDEssNoVersion]Remote Blob Store (RBS) BLOB objects (blobs). [!INCLUDEssHADR] protects any RBS metadata and schemas stored in an availability database by replicating them to the secondary replicas. This is the SharePoint Content Database. Generally speaking, [!INCLUDEssNoVersion] stores this RBS metadata independently from the blob.
The protection for RBS BLOB data depends on the BLOB Store Location, as follows:
| BLOB Store Location | Can Availability Groups Protect This BLOB Data? |
|---|---|
| The same database that contains the RBS metadata (stored using a RBS remote FILESTREAM provider) | Yes |
| Another database in the same instance of [!INCLUDEssNoVersion] (stored using a RBS remote FILESTREAM provider) | Yes We recommend that you put this database in the same availability group as the database that contains the RBS metadata. |
| Another database in a different instance of [!INCLUDEssNoVersion] (stored using a RBS remote FILESTREAM provider) | Yes This database must be in a separate availability group. |
| A third-party BLOB store | No To protect this BLOB data, use the high-availability mechanisms of the BLOB store provider. |
- RBS maintainers need to be targeted on the primary replica.
- Use an availability group listener. For more information, see Availability Group Listeners, Client Connectivity, and Application Failover (SQL Server).
