 # Configure high availability and disaster recovery for SQL Server on Linux
+
+SQL Server on Linux supports high-availability and disaster recovery. On the most basic level, you can backup and restore databases in the same way you backup and restore SQL Server on Windows. In more advanced scenarios SQL Server also supports a shared-disk failover cluster on Linux servers with Red Hat Enterprise Linux 7.0 HA or greater. Future releases of SQL Server on Linux may include additional high-availability capabilities.
+
+## Backup and restore databases
+
+You can restore SQL Server databases to vNextCTP1 from SQL Server 2012 and newer, as long as the database comes from a SQL Server build that is less than or equal to the version of SQL Server where you are restoring the database. The restore commands are the same as the restore commands for SQL Server on Windows. 
+
+SQL Server on Linux can restore databases from backups SQL Server on Windows or Linux as long as the SQL Server version is supported. 
+
+SQL Server on Windows can restore databases from backups on either operating system as long as the SQL Server version is supported. 
+
+## Shared-disk failover clusters
+
+You can create a shared disk failover cluster for SQL Server on Red Hat Enterprise Linux 7 with the HA add-on. On this type of cluster, storage is presented to cluster nodes. The instance of SQL Server can be active on any one node in the cluster. If the HA add on detects an interruption of the SQL Server service, the HA solution can move the service to another node. For details see [Configure shared disk cluster for SQL Server on Linux](sql-server-linux-configure-shared-disk-cluster.md)
