With this release, VMware updated its licensing policy and asked its partners to follow these changes accordingly. On June 4, 2. 00. Veeam published the following press release As a longtime Premier Technology Alliance Partner and supporter of VMwares product strategy, Veeam Software takes great pride in creating innovative software products that enhance the customer value of VMware ESX, ESXi and ESXi Free, said Ratmir Timashev, Veeam president and CEO. One such example is support for the free edition of VMware ESXi in Veeam Backup Replication. Recently, VMware requested that Veeam discontinue support for ESXi Free in Veeam Backup Replication in order to comply with VMwares updated licensing policy, Timashev continued. In light of VMwares request, and our close technical partnership, Veeam Backup Replication will no longer support ESXi Free licensed ESXi is fully supported. We will still continue to offer support for ESXi Free to existing Veeam customers who purchased Backup Replication prior to version 3. Thus, starting from Veeam Backup Replication 3. ESXi 4. 0, these 2 products and their new versions dont work together. Fast forward to 2. Even though the world has changed a lot for example, ESX was discontinued in favor of ESXi the situation remains the same and the latest Veeam Backup Replication v. Microsoft Word Templates Project Charter Template there. ESXi 6. 0 environment. In the article below, I will explain from the technical point of view why it occurred that way and what can be done if you happened to use free ESXi. New features in ESXESXi 4. In order to overcome the limitations of traditional physical backup policies and legacy approaches, VMware used a VMware Consolidated Backup VCB in ESXESXi prior to version 4. VCB was a module that ran on a dedicated proxy backup server, gathered snapshots of each VMs disk image and backed them up by itself. The VCB feature was a step forward toward simplicity compared to traditional backups. However, in addition to requiring a separate server the proxy, it had some limitations, including the absence of incremental backups and the temporarily doubled IO load on production storage. Starting with ESXESXi 4. VMware replaced its VCB technology with innovative VMware v. Sphere Storage APIs VADP along with the Change Block Tracking CBT mechanism. VADP was next generation of VMwares data protection framework and extremely useful for backup utilities. Using VADP, the backup application triggers the API to kick off the snapshot process and then backs up the resulting data set by mounting the snapshot and storing the data in a backup file. This provides an easy way for the backup software to take image level backups of VMs directly. On the other hand, CBT allows applications to get a list of blocks that have changed since the last backup point or time point in the past and makes subsequent backups using the changed data only. This obviously requires less time and space for incremental files. Another great and important feature of ESXESXi 4. Hot Add. This mechanism adds disks on the fly from one VM to another. It allows users to copy data directly from one disk to another without using network stack, which significantly reduces network traffic and time needed for the process. Backup and recovery products can offload specific VM and storage management operations to compliant storage hardware so the host executes these operations faster and consumes fewer resources. With these advancements, backup solutions were able to perform their operations much faster, substantially reducing the backup window and decreasing the systems recovery point objectives RPO and recovery time objectives RTO. As a price for the innovations, VMware didnt make new APIs to be available with free ESXESXi, so Free ESXESXi have had several limitations ever since, including No support of v. Center agent VMware APIs are in read only state. VMware APIs, including VADP, cannot be launched. Unlocking these settings is easy if one applies a paid VMware license. The minimum VMware licensing VMware v. Sphere Essentials Kit does that, and it gives the administrators all of the beauty of modern virtualization technologies, including ability to use Veeam Backup Replication or Veeam Backup Free for VM data protection. Now, heres a quick Q A round. Q What if I use Veeam Backup Replication Veeam Backup Free for free ESXiA If you attempt to perform a backup operation with Veeam Backup Replication or Veeam Backup Free Edition for a VM running on free ESXi, you will see the following error message Error Cant create snapshot, current license or ESXi version prohibits execution of the requested operation. Veeam Backup Free and free ESXi 5. Q Ok. What about restore operations Is that the same A Restore operations like Instant VM Recovery, entire VM restore and hard disks restore fail with the same error. However, the VM files restore operation works fine. It will gently upload files as if you were doing it via the v. Sphere datastore browser. When the operation is complete, you will need to go to the host and register the restored VM by right clicking its VMX file and selecting add to inventory. At this point, the restored VM will be registered on the free host and youll be able to use it. This is a great tip if you want to play with a copy of your production VM at home. Q I use free ESXi already, how can I protect VMs A There is always a workaround, and in this case, its not that complicated. You still can treat VMs working on a free ESXi like you would treat physical servers. For instance, install Veeam Endpoint Backup FREE inside of Windows guest OS, select the backup scope and schedule the job. Data residing on such VM will be fully protected and ready to be restored at your convenience. Q What about my Linux VMs A As for the Linux VMs, you can use the manual VM export turn VM off and copy VM files from ESXi datastore to your backup storage. However, we are going to have a new product that will make the things much easier here Veeam Backup for Linux. We expect it to be available on the market soon. This product will take care of any Linux VM regardless of its nature physical or virtual, allowing you to protect the data easily and efficiently. Q Is there any other product helping me with free ESXi management A In addition to that, let me remind you that Veeam ONE Free Edition does support v. Sphere Hypervisor free ESXi. With this instrument, you get powerful monitoring, reporting and capacity planning of your virtual infrastructure allowing you to prevent issues before they have any operation impact on the system. Conclusion. VMware developed powerful APIs for v. Sphere hosts, but they are only available with a paid license. As a third party vendor, Veeam requires a licensed host to provide full ESXi backup and recovery support for 1. The backup and recovery support also relies on VADP and its features. This is the only VM backup and recovery method VMware recommends, and it establishes differences between physical and virtual environments, which allows admin to take advantage of agentless backup solutions in virtual infrastructures.
