Major features in Vembu BDR Suite
Agentless VMware Backup and Replication
Vembu designed VMware backup protects vSphere and vCenter environments using VMware vStorage APIs (VADP). Users can backup and replicate unlimited VMs from VMware vSphere ESXi hosts without installing any agents inside VMs. Direct Hot-Add and SAN transport mode provides faster data transfer speed with less resource utilization. VMBackup will auto analyze the VMware environment and assigns the appropriate data transfer mode.
Agentless Microsoft Hyper-V Backup with Changed Block Tracking Incremental
Backup VMs running in a Hyper-V host without installing agent on individual VMs. Vembu’s proprietary Hyper-V CBT driver tracks the changed blocks in an efficient manner and runs incremental backups 5X faster!
Disk Image Backup for Windows Servers and Workstations deployed in Physical Environments
Backup entire image of physical Windows Servers and Workstations which includes operating system, application and user data in a periodic fashion which can be disaster recovered to same or new hardware as entire machines and can also instant accessed in any virtual environment via quick boot options.
File & Application Backup for Windows, Linux and Mac
Vembu supports file and application level backup for all Windows, Linux and Mac operating system running machines. Backup support to system folders such as My Documents, My Photos, Desktop, Browsers and etc., is also provided.
Application-Aware Image Backups
Vembu use application-specific VSS writers to take consistent snapshots of highly transactional applications like Microsoft Exchange, SQL Server, Active Directory and SharePoint during VM and disk image backup. Transaction log files are truncated at the end of each successful backup schedule.
Basic and Advanced (GFS) Retention Policies
The Multilevel GFS retention reduces the time taken to restore backed up machines and most importantly reduces the size of image files in storage location. It also helps to avoid long chains of incrementals, ensuring safety of backup data and allows you to meet the requirements of your retention policy.
Automatic Backups Verification
Vembu BDR Suite image verification process ensures that disk image backup data (physical disk image, vmware and hyper-v backups) are in a bootable state. The integrity of backup data can be easily verified by monitoring the screenshots of the boot screen everyday.
Advanced Reverse Incremental with Any-Point-In-Time Full
Since every incremental is a self-sufficient snapshot with pointers to the blocks in VHFS, any incremental is instantaneously available as a full backup. There is no extra processing to restore an incremental backup compared to a full backup (no need for a merge).
Quick VM Recovery
This provides the flexibility to boot any incremental VM and physical machine disk image backup instantly. For Windows based BDR backup servers, machines are recovered instantly with Microsoft Hyper-V. In the case of Linux based BDR backup servers, Quick VM recovery is done with the help of KVM.
Instant File Recovery
You can restore individual files and folders from VM and disk image backup without restoring entire backed up VM or physical Windows machine.
Permanent VM Recovery
The backed up VMware and Hyper-V VMs can be permanently recovered to the same or different hosts after any major disaster or VM crash.
Failover and Failback
The replicated VMware VMs from the target hosts can be instantly failover on target host during VM crash. Also, it can be failbacked to the source ESXi host at anytime.
The entire crashed physical system can be restored to same hardware or new RAW hardware by using Vembu Recovery CD.
Vembu Universal Explorer
Vembu developed an exclusive free tool called Vembu Universal Explorer to instantly recover the individual Microsoft application items from the backed up data. Be it physical or virtual machine data, Vembu Universal Explorer recovers application items from Microsoft Exchange, SharePoint, SQL and Active Directory without restoring the entire VM backup and disk image backup.
VMware Disk Level Recovery
VMware disk level restore allows you to restore only required disks during recovery instead of the entire VM. You can essentially restore any specific disks to the same VM or a different one.
Restore VMware, Hyper-V and Physical Windows Disk Image Backups in VHD,VHDX, VMDK, Flat-VMDK and RAW formats
Since VMware, Hyper-V and Physical Windows Disk Image backups are stored at block level in a neutral format, Vembu BDR Suite makes it possible to instantly restore any incremental backup in any virtual disk format including VHD, VHDX, VMDK, VMDK-FLAT or IMG.
Rebuild Vembu BDR Server After a Disaster
There are endless reasons why an OS can get corrupted, resulting in a disaster if you have not backed up your server machine. Vembu BDR has the ability to reconstruct all the backup metadata information from storage repositories and restore the entire backup server setup to its previous state.

Known Issues & Limitations
- VMware backup does not support backup of virtual machines with independent disks.
- Application aware backup is not supported for 32 bit Guest OS
- Vembu VMBackup does not support VMware backup for ESXi free versions as VMware APIs themselves do not support ESXi free versions
- VMWare backup is not supported if the virtual disk resides in RDM datastore
- VMWare backup is not supported if the Guest OS hardware version is lower than v7
- In VMWare backups, if any snapshot is reverted, further incremental backups will fail
- To use VMware Hot-Add Data Transfer mode , the agent must be installed on the Virtual Machine on the same ESXi server where the source VMs reside
- If the proxy VM in which the backup agent is running is on a VFMS3 datastore, the volume on the proxy VM should be formatted with appropriate block size given below, depending on the maximum disk size of the source VM(s)
- 1MB block size – support up to 256GB
- 4MB block size – Support up to 1024GB
- 8MB block size – Support up to 2048GB
- The disks that are to be Hot-Added must be SCSI. IDE drives are not compatible with hotadd
- The proxy VM should have installed VMware tools and VMware tools should be upgraded immediately to the available newer version

VMware VM Replication with FailOver & FailBack:
- CD/DVD drives of virtual machines will not be replicated to the target host
- Resizing virtual disks after initial replication in the primary site will result in replication job failure permanently. Users have to configure a new job again to perform replication
- Source VM’s VMXNET3 ethernet adapter configuration will not be replicated to the replica VM
- If the initial replication job fails intermittently during replication, users have to delete the replica VM in the target site and create a new job to perform the replication
- The VM should not be manually powered off or powered on after the FailOver & FailBack respectively. This may leads to data lose
- If the FailBack fails intermittently, users have to delete the FailBack VM in the target site and try again
