Vladan’s recent article, Vembu BDR Suite – Back to Business in few minutes with Quick VM Recovery is one among the series of articles written about Vembu’s flagship offering, Vembu BDR Suite and its comprehensive features. This specific article talks about one of the most important aspects needed for business continuity which is Recovery. Vembu VMBackup ensures industry best recovery time objectives (RTO) < 15 minutes by delivering quick recovery features, which helps to recover entire VM including OS and applications, individual files and individual items from Microsoft Applications. The detailed article by Vladan begins with an introduction of Quick VM recovery feature of Vembu which picks the backups (those are deduplicated and compressed) and boots them on the hypervisor of your choice which are VMware, Hyper-V or KVM. Then the article explains how the system reads the backup data from storage repository and creates immediately files which are exposed through the Vembu Virtual Drive. The files are created in VMDK, VHD, VHDX, IMG formats respectively. Vembu provides an option to store the backups as chunk files which are encrypted and de-duplicated are stored in Vembu Database using Vembu’s own file system, VembuHIVE. Once mounted, the files are exposed through Vembu Virtual Drive. Since it is a virtual drive, no physical storage is needed. With the virtual VMDK, you can create a VM on ESXi host and point back to the Vembu repository which is exposed as NFS datastore. Similar way you can also expose Hyper-V VM and pick a VHD/VHDX which allows you to create VM on Hyper-V host. Note that there are other file, with extension IMG, and those files can instantly create VMs which are created on KVM Hypervisor.
The article then moves to the steps of performing a quick VM recovery which comprises of mounting the backup, selecting the Instant VM Recovery option, options of selecting software for recovery, option to select vCenter server and ESXi host, target datastore and then running the recovery process. The process of Hyper-V is also explained subsequently. What is impressive is you can restore either on VMware ESXi or Hyper-V host (or even KVM) as you have those files at your fingertips. This is not a usual and common feature that every backup vendor can provide. The VM boots up directly from the backup file, but to maintain the integrity of the backup data, all the modifications after booting a VM are stored in a separate virtual hard disk file. Finally, Vladan explains about multiple recovery options available in Vembu BDR in physical windows system (You can simply enable Hyper-V or KVM role and you can use this server to instantly recover VMs from backups which lay on that particular server. You can also recover backups of physical machines and have them boot up as VMs) and windows VM (You can share the Vembu virtual drive by mounting via NFS, OR by using SMB share and do Instant Recovery of VMs (or physical machines) on any Hyper-V server running in your IT environment)
