Vembu 3.9.0 – new features are coming… (partner post)


Vembu soon will bring out the new version 3.9.0 and they just prepared some new cool features that will be very welcome to the current customers and also to those who wants to have a complete tool for the Backup and DR.

Take a look to the new incoming features:

Tape Backup Support:

Vembu extends its support to native tape backup through the Vembu BDR console. You can utilize the best known 3-2-1 backup strategy of having 3 copies of backup data in 2 different media and 1 off-site location for an efficient DR plan. This secondary backup approach will help you to archive the image based backups in both virtual and physical environments like VMware, Hyper-V and Windows Servers and recover them in multiple formats like VHD, VMDK, VHDX, VMDK-Flat and RAW.

Auto Authorization at Off-site DR:

Enabling the auto authorization feature will allow only the authorized Vembu BDR servers to get connected with Vembu OffsiteDR servers (Replication) using the registration key.

Quick VM Recovery on ESXi for Hyper-V and Disk Image Backups:

Instant recovery of backed up data on VMware ESXi is now made available for both the Hyper-V VMs and Windows Servers backup jobs for an effective Disaster Recovery. This recovery of the virtual machines happens in a matter of seconds by booting the backed up machine directly from the backup storage repository, from where all the files, folders and applications can be accessed.

Windows Event Viewer Integration:

All the events of the Vembu BDR, Off-siteDR & agents like information on critical, warnings and major events are updated in the Event Viewer of Windows Servers  when enabled for better management.

Advanced Backup level encryption for all agents:

Users will be able to configure AES-256 bit encryption for all their backup jobs of VMware, Hyper-V, Disk Image through their customized passwords using corresponding password hints as well.

OffsiteDR Server retentions using Vembu Network Backup:

OffsiteDR retention policies is now available for the Network Backup plugins too, like the image based backups of VMware, Hyper-V and Disk Image backups at the too.

Listing of files & Folders in aciTree structure:

The listing of files and folders while configuring backups on a Network Backup plugin is now up with the aciTree structure for easy and quick navigation. 

Pre/Post backup scripts for all Network & Image Backup clients:

This feature provides the ability to configure running custom actions before and after the execution backup schedule. The custom actions may include running an application using some script files.

 AngularJS conversion of UI for Vembu OnlineBackups:

The overall UI of Vembu OnlineBackup is improved for better performance like the current Vembu BDR and Off-siteDR.

Update of consumed space on the Vembu Portal:

Based on the display of the consumed space of Vembu Online Backup and SaaSBackup plugins, the customer will be able to allocate and purchase further cloud storage post purchase and upgrade.

This latest Free edition of Vembu BDR Suite was designed understanding the setbacks by any common IT Administrator. Thence  making Vembu an important name in the market for backup vendor for its enterprise level product for SMBs. This free edition is free forever and IT administrators can continue managing their backups with the trial version without any feature restriction. Let’s take a plunge into the detailed features of this Free edition.

Unlimited features for Limited environment(3 VMs):

Using the Vembu BDR Suite in its trial version does not require purchasing a license. This category of the Free edition offers unlimited features and few of them are listed below:

  1. Agentless VMware backups for multiple VMs: Configuring backups for protecting multiple VMs without physically installing any agent.
  2. Disk Image Backups from BDR Server: Disk Image Backups can now be configured and managed via Vembu BDR Server. Relying on proxy agents is no longer required, unless it’s a distributed deployment which require individual proxy agent installation.
  3. Full VM Backup: Will backup the entire VM including OS, applications and the data.
  4. Storage Pooling: Storage Pools are used to aggregate the space available from different volumes and utilise them as a storage for specific backups. The hybrid volume manager of Vembu BDR Server supports scalable and extendable backup storage for different storage media such as Local drives, NAS(NFS and CIFS) and SAN(iSCSI and FC). Vembu BDR provides storage pooling option for both backup level and group level.
  5. LAN free data transfer using SAN and Hot- Add modes:Vembu VM backup support Direct SAN, Hot-Add and network transport mode to backup the VM data.
  6. Auto Authorization: Enabling Auto authorization in Vembu BDR allows proxy agents to get registered to backup server using unique registration key generated by respective BDR server.
  7. Automatic Backup Scheduling: Backups can be automatically scheduled as per the user’s flexibility
  8. Encryption Settings: Users can now provide additional security to their disk based backup jobs by assigning custom-password to backup server, such that all their backup data will be encrypted and can be restored/accessed only by providing the custom-password.
  9. FLR from GUI (Backup & Replication): File Level Recovery(FLR) is now available for both backup and replication jobs where user can choose specific files and folders from VMware/Hyper-V/Disk Image backups and VMware replication, to be restored in a quick fashion.

All the above major features are included in this free edition for 3 virtual machines. Let’s get to know those restricted features for unlimited virtual machines.

Restricted Features for unlimited virtual machines:

All the features mentioned above for limited business environment will be applicable for this categories with few restrictions in the features. They are:


  1. Application aware processing: Configuring them for a Hyper-V environment is restricted but that does not hold good with VMware vSphere Esxi(s).
  2. Changed Block Tracking: Only the incremental blocks which are changed since the previous backup will been tracked and  backed up in the successive backup schedule thereby reducing disk space and time
  3. Retention Policies: User can retain any number of recovery points of his own choice. They come to great use when it comes to store the backup data.
  4. Near CDP: Incremental backup can be scheduled every 15 mins to ensure the RPO < than 15 mins
  5. Quick VM recovery to ESXi: Incremental backup can be scheduled every 15 mins to ensure the RPO < than 15 mins.
  6. Automated Backup verification: Verify the recoverability of the backed up images and screenshot of the booted Image backup will be mailed

Backup and recovery holds good for both physical and virtual environments and makes granular recovery possible with great ease.You will able to scale out your storage, secure your individual backup jobs with in-built deduplication, encryption and compression that makes its own file system called, the VembuHIVE.

This latest Free edition thus becomes one of the most business-friendly and a complete backup solution. That being said,  It can be suitable for both testing and production environments! Their out-of-the box policy- backup for all was hailed even at the recent VMworld event, Las Vegas.

Well, there is nothing left to ponder now. It’s time to make the right decision. It could be done right away with getting started with their Free edition of Vembu BDR Suite on a 30 days free trial. Click here.
