Set up disaster recovery of on-premises VMware virtual machines or physical servers to a secondary site
InMage Scout in Azure Site Recovery provides real-time replication between on-premises VMware sites. InMage Scout is included in Azure Site Recovery service subscriptions.
The Azure Site Recovery scenario for replication between on-premises VMware or physical datacenters is reaching end-of-support.
- From August 2018, the scenario can’t be configured in the Recovery Services vault, and the InMage Scout software can’t be downloaded from the vault. Existing deployments will be supported.
- From December 31 2020, the scenario won’t be supported.
- Existing partners can onboard new customers to the scenario until support ends.
During 2018 and 2019, two updates will be released:
- Update 7: Fixes network configuration and compliance issues, and provides TLS 1.2 support.
- Update 8: Adds support for Linux operating systems RHEL/CentOS 7.3/7.4/7.5, and for SUSE 12
After Update 8, no further updates will be released. There will be limited hotfix support for the operating systems added in Update 8, and bug fixes based on best effort.
Azure Site Recovery continues to innovate by providing VMware and Hyper-V customers a seamless and best-in-class DRaaS solution with Azure as a disaster recovery site. Microsoft recommends that existing InMage / ASR Scout customers consider using Azure Site Recovery’s VMware to Azure scenario for their business continuity needs. Azure Site Recovery's VMware to Azure scenario is an enterprise-class DR solution for VMware applications, which offers RPO and RTO of minutes, support for multi-VM application replication and recovery, seamless onboarding, comprehensive monitoring, and significant TCO advantage.
As an alternative, we recommend setting up disaster recovery for on-premises VMware VMs and physical machines by replicating them to Azure. Do this as follows:
- Review the quick comparison below. Before you can replicate on-premises machines, you need check that they meet requirements for replication to Azure. If you’re replicating VMware VMs, we recommend that you review capacity planning guidelines, and run the Deployment Planner tool to identity capacity requirements, and verify compliance.
- After running the Deployment Planner, you can set up replication: o For VMware VMs, follow these tutorials to prepare Azure, prepare your on-premises VMware environment, and set up disaster recovery. o For physical machines, follow this tutorial.
- After machines are replicating to Azure, you can run a disaster recovery drill to make sure everything’s working as expected.

Bug fixes and enhancements
Fixes for increased Windows cluster support reliability:
- Fixed- Some of the P2V MSCS cluster disks become RAW after recovery.
- Fixed- P2V MSCS cluster recovery fails due to a disk order mismatch.
- Fixed- The MSCS cluster operation to add disks fails with a disk size mismatch error.
- Fixed- The readiness check for the source MSCS cluster with RDM LUNs mapping fails in size verification.
- Fixed- Single node cluster protection fails because of a SCSI mismatch issue.
- Fixed- Re-protection of the P2V Windows cluster server fails if target cluster disks are present.
Fixed: During failback protection, if the selected master target server isn't on the same ESXi server as the protected source machine (during forward protection), then vContinuum picks up the wrong master target server during failback recovery, and the recovery operation fails.
- The P2V cluster fixes are applicable only to physical MSCS clusters that are newly protected with Site Recovery Scout Update 5. To install the cluster fixes on protected P2V MSCS clusters with older updates, follow the upgrade steps mentioned in section 12 of the Site Recovery Scout Release Notes.
- if at the time of re-protection, the same set of disks are active on each of the cluster nodes as they were when initially protected, then re-protection of a physical MSCS cluster can only reuse existing target disks. If not, then use the manual steps in section 12 of Site Recovery Scout Release Notes, to move the target side disks to the correct datastore path, for reuse during re-protection. If you reprotect the MSCS cluster in P2V mode without following the upgrade steps, it creates a new disk on the target ESXi server. You will need to manually delete the old disks from the datastore.
- When a source SLES11 or SLES11 (with any service pack) server is rebooted gracefully, then manually mark the root disk replication pairs for re-synchronization. There's no notification in the CX interface. If you don't mark the root disk for resynchronization, you might notice data integrity issues.

- For all new installations, use the new configuration server and Windows master target GA bits.
- Update 4 can be applied directly on 8.0.1 GA.
- The configuration server and RX updates can’t be rolled back after they've been applied.
Azure Site Recovery Scout 8.0.1 Update 3
All Site Recovery updates are cumulative. Update 3 contains all fixes from Update 1 and Update 2. Update 3 can be directly applied on 8.0.1 GA. The configuration server and RX updates can’t be rolled back after they've been applied.
Bug fixes and enhancements
Update 3 fixes the following issues:
- The configuration server and RX aren't registered in the vault when they're behind the proxy.
- The number of hours in which the recovery point objective (RPO) wasn't reached is not updated in the health report.
- The configuration server isn't syncing with RX when the ESX hardware details, or network details, contain any UTF-8 characters.
- Windows Server 2008 R2 domain controllers don't start after recovery.
- Offline synchronization isn't working as expected.
- After VM failover, replication-pair deletion doesn't progress in the configuration server console for a long time. Users can't complete the failback or resume operations.
- Overall snapshot operations by the consistency job have been optimized, to help reduce application disconnects such as SQL Server clients.
- Consistency tool (VACP.exe) performance has been improved. Memory usage required for creating snapshots on Windows has been reduced.
- The push install service crashes when the password is larger than 16 characters.
- vContinuum doesn't check and prompt for new vCenter credentials, when credentials are modified.
- On Linux, the master target cache manager (cachemgr) isn't downloading files from the process server. This results in replication pair throttling.
- When the physical failover cluster (MSCS) disk order isn't the same on all nodes, replication isn't set for some of the cluster volumes. The cluster must be reprotected to take advantage of this fix.
- SMTP functionality isn't working as expected, after RX is upgraded from Scout 7.1 to Scout 8.0.1.
- More statistics have been added in the log for the rollback operation, to track the time taken to complete it.
- Support has been added for Linux operating systems on the source server:
- Red Hat Enterprise Linux (RHEL) 6 update 7
- CentOS 6 update 7
- The configuration server and RX consoles now show notifications for the pair, which goes into bitmap mode.
- The following security fixes have been added in RX:
- Authorization bypass via parameter tampering: Restricted access to non-applicable users.
- Cross-site request forgery: The page-token concept was implemented, and it generates randomly for every page. This means there's only a single sign-in instance for the same user, and page refresh doesn't work. Instead, it redirects to the dashboard.
- Malicious file upload: Files are restricted to specific extensions: z, aiff, asf, avi, bmp, csv, doc, docx, fla, flv, gif, gz, gzip, jpeg, jpg, log, mid, mov, mp3, mp4, mpc, mpeg, mpg, ods, odt, pdf, png, ppt, pptx, pxd, qt, ram, rar, rm, rmi, rmvb, rtf, sdc, sitd, swf, sxc, sxw, tar, tgz, tif, tiff, txt, vsd, wav, wma, wmv, xls, xlsx, xml, and zip.
- Persistent cross-site scripting: Input validations were added.
Azure Site Recovery Scout 8.0.1 Update 2 (Update 03Dec15)
Fixes in Update 2 include:
- Configuration server: Issues that prevented the 31-day free metering feature from working as expected, when the configuration server was registered to Azure Site Recovery vault.
- Unified agent: Fix for an issue in Update 1 that resulted in the update not being installed on the master target server, during upgrade from version 8.0 to 8.0.1.
Azure Site Recovery Scout 8.0.1 Update 1
Update 1 includes the following bug fixes and new features:
- 31 days of free protection per server instance. This enables you to test functionality, or set up a proof-of-concept.
- All operations on the server, including failover and failback, are free for the first 31 days. The time starts when a server is first protected with Site Recovery Scout. From the 32nd day, each protected server is charged at the standard instance rate for Site Recovery protection to a customer-owned site.
- At any time, the number of protected servers currently being charged is available on the Dashboard in the vault.
- Support was added for vSphere Command-Line Interface (vCLI) 5.5 Update 2.
- Support was added for these Linux operating systems on the source server:
- RHEL 6 Update 6
- RHEL 5 Update 11
- CentOS 6 Update 6
- CentOS 5 Update 11
- Bug fixes to address the following issues:
- Vault registration fails for the configuration server, or RX server.
- Cluster volumes don't appear as expected when clustered VMs are reprotected as they resume.
- Failback fails when the master target server is hosted on a different ESXi server from the on-premises production VMs.
- Configuration file permissions are changed when you upgrade to 8.0.1. This change affects protection and operations.
- The resynchronization threshold isn't enforced as expected, causing inconsistent replication behavior.
- The RPO settings don't appear correctly in the configuration server console. The uncompressed data value incorrectly shows the compressed value.
- The Remove operation doesn't delete as expected in the vContinuum wizard, and replication isn't deleted from the configuration server console.
- In the vContinuum wizard, the disk is automatically unselected when you click Details in the disk view, during protection of MSCS VMs.
- In the physical-to-virtual (P2V) scenario, required HP services (such as CIMnotify and CqMgHost) aren't moved to manual in VM recovery. This issue results in additional boot time.
- Linux VM protection fails when there are more than 26 disks on the master target server.
