Instant VM Recovery. Granular Restore. Low Price.
VMware Backup and Disaster Recovery Solution

Ahsay's VMware backup and disaster recovery solution promises quick, safe and easy protection for the entire VMware environment of your customers. With our VM Run Direct instant recovery and Granular Restore capabilities, as well as some third-party tools and your expertise in IT network management, MSPs are well positioned to offer a total Disaster Recovery as a Service (DRaaS) solutions to your end customers.



  • Get started easily - by simply provisioning a VMware ESXi host for disaster recovery (DR host) in your datacenter along with your AhsayCBS backup server
  • Give a peace-of-mind to customer - by remotely monitoring the health of your customer's production host with free third-party's monitoring tool
  • Meet tight RPO - with our VM Continous Backup feature
  • Meet tight RTO - by instantly spinning-up your customer's VMs on your DR host, and switching the traffic to the spun-up VMs on your DR host when customer's production host failed
  • Easy failback - by quickly switching back the traffic back to your customer's production host after on-premises environment is repaired
  • New recurring income opportunities - by converting the customer to use your hosted VM service after the disaster
  • Comprehensive endpoint backup options, e.g. Exchange, SQL, Oracle, MySQL, Lotus Domino, VMware, Hyper-V, Office 365, cloud to cloud, etc.
  • Fast multi-thread incremental backup to your datacenter or your public cloud storage account
  • Data retention policy and file versioning
  • Daily and per job email reports to clients
  • End to end encryption, compression, in-file deduplication

Granular Restore of files from Guest VMs

Granular Restore enables you to access and restore any files from a single pass backup, without the need to restore an entire VM, boot up the VM, or perform a secondary redundant backup. This dramatically reduces the recovery time objective (RTO) and storage resources on a second file level backup.

Spin-up VM instantly

If a backed up VM is failed or deleted accidentally, our VM Run Direct feature allows you to keep the downtime within minutes, as you can run the VM directly from its backup file on its original or standby host, without the need to restore the full backed up image file first.

Live VM migration with or without vMotion

With the VM Run Direct feature, you can choose to migrate the running backup VM to its original or an alternate host machine with or without VMware vMotion license.

Point in time VM restore

Our VM Run Direct or full VM restore allow you to run or restore a VM from any point in time that it was backed up. The VM booted up or restored will appear on the VMware ESXi host you selected for restore.

Backup through vCenter or a standalone machine

Ahsay VMware backup solution can be deployed in VMware environment with or without a vCenter server, therefore highly flexible. Even you just got one or two ESXi host without vCenter, you can still properly backed up them.

VMware VDDK / CBT supported

Our solution supports the latest VMware's native VDDK and CBT (changed block tracking) technologies that enable fast incremental backup and recovery of your Guest VMs.

ESXi free version supported

Unlike other backup solutions which only support ESXi paid version, Ahsay VMware backup solution extended our support to ESXi free version users. Although you can't use Granular Restore or fast VDDK mode with CBT for Run Direct , you can still make use of our non-VDDK mode to back up all your VMs.


The multi-threading implementation in Ahsay VMware backup solution will utilize the computing power of multiple CPU cores for creating multiple backup and restore threads to give you super-fast VM backup and restore performance.

Multi-destination backup to local and cloud destinations

You can back up the VMware Guest VMs to multiple destinations to minimize the risk of data loss, including local drive (of the vCenter or standalone machine), network share, FTP/SFTP server, and public cloud storage sequentially or concurrently. Granular Restore supports all destinations, whereas Run Direct supports AhsayCBS and local storage destination.

Flexible retention policy

Ahsay VMware backup solution allows you set flexible retention policies, including daily, weekly, monthly, yearly policies to suit your IT audit and compliance needs.

Manage all backup users through a centralized web console

In case you have many VMware hosts managed by many system administrators, Ahsay VMware backup solution allows you to create multiple backup user accounts for these administrators in a centralized management software, and centrally monitor and manage their activities through a web console. Clear audit trail is available for compliance purpose.

Fully rebrandable for MSPs

All graphics and wordings in the AhsayCBS centralized backup server and AhsayOBM client backup application are fully rebrandable and customizable for MSPs.

Preparation :

Deploy AhsayCBS backup server in your datacenter. Since you are going to offer DRaaS to your customers, this AhsayCBS machine has to be very powerful for simultaneously spin-up multiple guest VMs.
Provision a VMware ESXi host in your datacenter as a DR host.
Prepare an AhsayOBM machine in your datacenter to backup the running VMs on the DR host.
We also suggest you to manage the DNS settings for your customer's production VMs so that you can quickly change the settings during disaster recovery.
In your customer's environment, use free remote monitoring tool like Zabbix to monitor the health of your customer's production host.

Deployment :

For each guest VM, create a VMware backup set with AhsayOBM installed on the vCenter or a standalone machine that is on the same network as the production VMware ESXi host. Enable Granular Restore and VM Run Direct features in the backup set, and set to back up to two destinations, one to local / mapped drive, and the other to your AhsayCBS backup server in datacenter.
When customer needs to restore individual files within a backed up VM, use the Granular Restore feature to open and/or restore the desired files quickly, without the need to spin-up the whole backed up VM.
If a particular VM failed on the production VMware ESXi host, use the VM Run Direct feature to spin-up the backed up VM from the local backup destination to the production ESXi host, and at the same time migrate the VM back to the host with our Live Migration feature.
When a disaster strikes the whole production ESXi host of your customer, you can spin-up all the backed up VMs on the DR host through AhsayCBS' agentless restore feature within minutes, and at the same time migrate those VMs to the DR host with our Live Migration feature.
After all the backed up VMs are migrated to the DR host, edit the DNS records to fail over the traffic to the spun-up VMs on your DR host.
Use your AhsayOBM machine in your datacenter to keep backing up the guest VMs running on the DR host.
After customer's site has been restored with all the original machines in place, customer can take the datacenter's guest VMs backup set to restore the VMs to the original production VMware ESXi host.
Change the DNS records to switch the traffic of the VMs from the DR host to the original production host.
