How to avoid VM sprawl and improve resource utilization in VMware and Veeam backup infrastructures
You're facing VM sprawl if you're experiencing an uncontrollable increase of unused and unneeded objects in your virtual VMware environment. VM sprawl occurs often in virtual infrastructures because they expand much faster than physical, which can make management a challenge. The growing number of virtualized workloads and applications generate “virtual junk” causing VM sprawl issue. Eventually it can put you at risk of running out of resources.

You're facing VM sprawl if you're experiencing an uncontrollable increase of unused and unneeded objects in your virtual VMware environment. VM sprawl occurs often in virtual infrastructures because they expand much faster than physical, which can make management a challenge. The growing number of virtualized workloads and applications generate “virtual junk” causing VM sprawl issue. Eventually it can put you at risk of running out of resources.

Getting virtual sprawl under control will help you reallocate and better provision your existing storage, CPU and memory resources between critical production workloads and high-performance, virtualized applications. With proper resource management, you can save money on extra hardware.

The ability to leverage the data at the disaster recovery target site or in the cloud for VM backup eliminates the impact on production workloads.

Zerto Offsite Backup in the Cloud

What is Offsite Backup?

Offsite Backup is a new paradigm in data protection that combines hypervisor-based replication with longer retention. This greatly simplifies data protection for IT organizations. The ability to leverage the data at the disaster recovery target site or in the cloud for VM backup eliminates the impact on production workloads.

Why Cloud Backup?

  • Offsite Backup combines replication and long retention in a new way
  • The repository can be located in public cloud storage, a private cloud, or as part of a hybrid cloud solution.
  • Copies are saved on a daily, weekly and monthly schedule.
  • The data volumes and configuration information are included to allow VM backups to be restored on any compatible platform, cloud or otherwise.
The Guide to Selecting Flash for Virtual Environments
High-performance flash-based storage has dramatically improved the storage infrastructure’s ability to respond to the demands of servers and the applications that count on it. Nowhere does this improvement have more potential than in the virtualized-server environment. The performance benefits of flash are so great that it can be deployed indiscriminately and still performance gains can be seen. But doing so may not allow the environment to take full advantage of flash performance. It may also b
Flash storage allows for a higher number of VMs per host. Increasing VM density reduces the number of physical servers required and thereby reduces one of the largest ongoing costs, buying more physical servers, which often are configured with multiple processors and extra DRAM. At the same time, the high performance and low latency of flash allows more mission critical applications to be virtualized. This report explains how storage and hypervisor vendors are getting smarter about leveraging this faster form of storage by including storage quality of service (QoS) intelligence in their systems or environments.
User Profile and Environment Management with ProfileUnity
This whitepaper has been authored by experts at Liquidware Labs in order to provide guidance to adopters of desktop virtualization technologies. In this paper, we outline how ProfileUnity was designed to address many of the shortcomings of Roaming Profiles, and basic profile management tools that are just a step away from roaming profiles, in managing user profiles and user-authored data over multiple desktop platforms, including physical upgrades and refreshes, Windows migrations and moves to
User Profile Management on Microsoft Windows desktops continues to provide challenges.  Most Administrators find that Roaming Profiles and even Microsoft UEV generally fall short due to several factors. Profile Corruption, Lack of Customization, and lack of Enterprise Features are just some of the top shortcomings of Microsoft Windows profile management with these options.

Basic tools such as roaming profiles do not support a mixed operating environment, therefore it does not allow users to move among desktops with mixed profile versions, e.g. Windows 7, Windows 10, Server2008, 2012 r2, etc.

The lack of support of mixed OS versions makes Microsoft profile management methods a serious hindrance when upgrading/migrating operating systems. Microsoft profile management tools also only support very limited granular management, so admins do not have the ability to exclude bloated areas of a user profile or to include files and registry keys outside of the profile. Profile bloat is one of the number one reasons for long logon times on Windows desktops.

Most organizations who will upgrade from a previous Windows® OS, such as Windows 7, to Windows 10, will want the flexibility to move at their own pace and upgrade machines on a departmental or ‘as needed’ basis.  As a result, management of Microsoft profiles and migration become a huge challenge for these environments because neither operation is seamlessly supported or functional between the two operating systems.  

A user’s profile consists of nearly everything needed to provide a personalized user experience within Windows.  If one could separate out the user profile from Windows and enable dynamic profiles that can adapt to any Windows OS version, several advantages can be realized:
  • User state can be stored separately and delivered just-in-time to enable workers to roam from workspace to workspace
  • Users’ profiles can co-exist in mixed OS environments or automatically migrate from one OS to the next, making OS upgrades easy and essentially irrelevant during a point-in-time upgrade
  • Integral policies and self-managed settings, such as local and network printer management, as well as security policies, can be readily restored in the event of a PC failure or loss (disaster recovery)
Given the growing complexity and diversity of Windows desktops technologies, today’s desktop administrators are looking for better ways to manage user profiles across the ever-increasing spectrum of desktop platforms available. In this whitepaper, we will cover the issues inherent with Roaming Profiles and how ProfileUnity addresses these issues.
Vembu Changes the Dynamics of Data Protection for  Business Applications in a vSphere Environment
This paper examines how to use Vembu BDR to implement distributed backup and disaster recovery (DR) operations in a centrally managed data protection environment with an ingenious twist. Rather than store image backups of VMs and block-level backups of physical and VM guest host systems as a collection of backup files, Vembu BDR utilizes a document-oriented database as a backup repository, dubbed VembuHIVE, which Vembu virtualizes as a file system.
Normal 0 false false false EN-US X-NONE X-NONE In this analysis, openBench Labs assesses the performance and functionality of the Vembu Backup & Disaster Recovery (BDR) host-level (a.k.a. agentless) data protection solution in a VMware vSphere 5.5 HA Cluster. For this test they utilized a vSphere VM configured with three logical disks located on separate datastores to support an Exchange server with two mailbox databases. Each of the mailbox databases was configured to support 1,000 user accounts.

This paper provides technically savvy IT decision makers with the detailed performance and resource configuration information needed to analyze the trade-offs involved in setting up an optimal data protection and business continuity plan to support a service level agreement (SLA) with line of business (LoB) executives.

To test backup performance, they created 2,000 AD users and utilized LoadGen to generate email traffic. Each user received 120 messages and sent 20 messages over an 8-hour workday. Using this load level, we established performance baselines for a data protection using direct SAN-based agentless VM backups.

In this scenario they were able to :

  • Finish crash-consistent incremental agent-less backups in 18 minutes, while processing our base transaction load of 12 Outlook TPS.
  • Restore a fully functional VM in less than 5 minutes as a Hyper-V VM capable of sustaining an indefinite load of 4 Outlook TPS
  • Recover all user mailboxes as .pst files from a host-level agentless VM backup with no need to schedule a Windows Client backup initiated within the VM’s guest Windows OS.
In a DR scenario, Vembu leverages the ability to restore a VM in any format, to provide an Instant-boot function, When Vembu Backup Server is installed on a server that is concurrently running Hyper-V, Vembu exports the datastores associated with a VM backup as Hyper-V disks and configures a VM to boot from the datastores.
True 15-Minute RTO for Mission-Critical VM Systems with Vembu VMBackup Replication
Vembu Backup & Disaster Recovery (BDR) provides IT with a Disaster Recovery Management (DRM) system capable of meeting even more aggressive RTO and RPO goals than the previous release. For highly active database-driven systems, Vembu VMBackup leverages VMtools and VMware Changed Block Tracking (CBT) to perform incremental backups in 15-minute intervals with minimal impact on query processing. As a result, IT can limit data loss to 15 minutes of processing on active mission critical VMs.

The only way to recover a VM with full functionality and full performance without performing an explicit restore operation is through VM replication. Maintaining a replica VM, however, requires frequent and potentially expensive update processes that involve both explicit backup and implicit restore operations. To enable the extensive use of replication by IT, VMBackup adds critical optimizations to both restore and replication operations that dramatically minimize overhead on ESXi hosts and production VMs to just VM snapshot processing. Specifically, a BDR Backup server running on a VM is able to leverage hot-add SCSI transfer mode to write logical disk and logical disk snapshot files directly to a vSphere datastore, without involving the ESXi host for anything more than creating a VM snapshot.

A key a value proposition for Vembu VMBackup is its ability to directly read and write all backup and restore data directly to and from a datastore snapshot. As a result, Vembu VMBackup offloads all I/O overhead from production VMs and ESXi hosts, which is critical for maintaining an aggressive DRM strategy in a highly active virtual environment. What’s more, the performance of Vembu VMBackup in openBench lab's test environment made it possible to enhance support for a mission-critical OLTP application running on a VM using a combination of incremental backups for backup and replication. As a result, they were able to comply with a 30-minute RPO, restore the VM to a production environment in 5 minutes, and return to full-production level processing of business transactions—850 cTPS—in under 15 minutes.

VMBackup adds a new replica management module that enables an IT administrator to fully manage an initial failover and later finalize failover or failback with consolidation. In addition, BDR backup server simplifies all management functions by eliminating the need to run a separate client module on a BDR backup server, which becomes its own client within the BDR reporting hierarchy.

Vembu OffsiteDR Server: Optimize RPO & RTO While Enhancing DR Resilience
Vembu BDR’s data protection solution enhances DRM operations by eliminating all potential single points of failure for restore functions. Using Vembu BDR Suite, IT is able to replicate backup data from multiple BDR Backup servers to a system running OffsiteDR Server within their own data center. As a result, IT garners an alternate system from which to recover protected VMs and physical servers using the same procedures that IT administrators employ on a BDR Backup server.

The ability to configure and deploy high-performance VMs within a vSphere virtual environment continues to put CIO’s under increasing pressure to deal with the rampant bête noire of IT: business continuity. What started with Line of Business (LoB) driven Service Level Agreements (SLAs) requiring IT to meet rigorous Recovery Time and Recovery Point Objectives (RTO and RPO) has grown into an auditable ISO standard (ISO22301) and an emerging software niche for Disaster Recovery Management (DRM) systems.

For this analysis, openBench Labs assessed the performance and functionality of the Vembu OffsiteDR Server, a DRM device that increases the resilience of recovery processes. Their initial intent was to examine the ability to restore data in the event of a catastrophic failure in vSphere environment, including:

  • A VM running BDR Backup server,
  • an ESXi host, and
  • a SAN device.

The full capabilities of Vembu OffsiteDR Server, however, quickly revealed that the device had a much broader operational impact. With the installation of OffsiteDR Server on an external physical server, they were free to configure end-to-end backup and restore operations in a way that optimized RTO and RPO for all business-critical application scenarios running in vSphere test environment.

In openBench lab's test environment, the combination of Vembu OffsiteDR Server deployed on a physical server with a Vembu BDR Backup server deployed on a VM provided a value proposition that extended far beyond the enhancement of DRM recovery resilience. With OffsiteDR Server installed on a physical server, they were able to optimally leverage VM and physical server platforms to easily implement all of the data protection functionality provided by Vembu BDR Suite, leverage all of the performance optimizations available to VMs in a vSphere environment, and do so in the most cost-effective system configuration.

StarWind Web-based Management
StarWind Web-based Management functionality allows you orchestrating your StarWind infrastructure via a web browser from any point of the world. This functionality provides two options for managing StarWind-based infrastructure remotely: by deploying StarWind Gateway VM, or by using StarWind Virtual Storage Appliance. Both ways are extra simple to follow and ensure the full control over storage-related operations.
StarWind Web-based Management functionality provides the ability to easily administrate the StarWind-based infrastructure remotely from a web browser on any device with internet connection. StarWind Web-based Management provides two ways for orchestrating the StarWind environment from a web browser:

By deploying StarWind Gateway VM

This option allows deploying a Linux-based virtual machine from a template. The VM will further accept incoming HTTP connections and transform them into RDP sessions. After setting up the Gateway VM and a target host, the user will be automatically directed into the RDP session on the target StarWind host after entering the VM IP in a web browser.

By deploying StarWind Virtual Storage Appliance (VSA)

By following this approach, the user deploys StarWind Virtual Storage Appliance as a Linux-based virtual machine from a template with a built-in HTTP > RDP “proxy” functionality. It can be further used as a full-fledged StarWind node, or for managing the existing StarWind infrastructure.

Both ways are extremely simple to implement and provide a full control over StarWind infrastructure from any remote location from a web browser.
