Microsoft Azure Site Recovery (Service)
Disaster recovery of Azure VMs
- Azure Site Recovery now supports replicating VMs deployed in an availability zone in an Azure region to another Azure region.
- Azure Site Recovery now supports firewall-enabled storage accounts. You can replicate virtual machines with unmanaged disks on firewall-enabled storage accounts to another Azure region for disaster recovery scenarios. You can also select firewall-enabled storage accounts in a target region as target storage accounts for unmanaged disks. You can restrict access to the cache storage account by allowing only the source Azure VM's virtual network to write to it. When you're using firewall enabled storage accounts, make sure that you enable the Allow trusted Microsoft services exception.
- Linux OS support improvements
- Support for Oracle Linux 6.8 and 6.9
- Support for Oracle Linux 7.0 to 7.5
- Support for UEK5 kernel
- Support for BTRFS file system
- Fixes certain cases in which a recovery plan failover fails for a few VMs. This issue can occur if the VM shutdown process takes too long.
Microsoft Azure Site Recovery (Portal)
- Improvement in which you can enable replication to another region for Azure VMs that are deployed in availability zones.
- Improves performance for replicated "Overview" and "Servers" pages.
- Fixes certain cases in which a replicated item list view was not loading.
- Fixes occasional failures in job notification displays.
- Fixes issues that affect getting recovery points during "failover" or "test failover in which users cannot trigger operations. The user can now trigger failover operations by using the Latest recovery point option.
- Fixes an issue in which the error details field is not visible in the configuration server page. The page is modified to a full screen page to show all the fields.
