Data protection software for ESXi Hypervisor 5.1, 5.5, 6.0, 6.5 & 6.7

Instant recovery, the only free differential backup tool for VMWare vSphere

Alert!  We offer support to free users through our community forum at Please, feel free to pose your questions and feature requests, we listen to our users.

Download here: free VMWare vSphere differential backup tool. Runs as a service in your ESXi host and backups your VMs automatically. Yes!, it does indeed backup VMs in unlicensed or free versions of the vSphere Hypervisor, AKA ESXi. XSIBackup is a free serious alternative to commercial software, it's used by governments and important institutions worldwide.

©XSIBackup works at the ESXi operating system level and uses the built in ESXi cron service to schedule backup jobs. It is managed through an SSH session as root, just as you would manage any Linux server. It has a minimum footprint on the server's resources yet offers close to hardware's theoretical limits at the time to backup data.

©XSIBackup is an extremely resilient piece of software, designed for professional system administrators that prefer reliable command line tools to fancy colourful windows. We nevertheless offer a more advanced version of the software that incorporates an SSH GUI to facilitate data input and minimize setup times.

• Compatible with the free and commercial versions of VMWare ESXi, from ESXi 5.1 upwards, including latest ESXi version 6.7
• Instant recovery of data, the backed up VMs are ready to be switched on.
• No limitations, no keys, no limit in the number of VMs you can backup.
• Cron programmable. Your backup tasks will be run automatically.
• Hot Backup of virtual machines, no downtime.
• Self contained, unattended backups of servers, no need for extra HW.
• Automatic provisioning of space, backup rotation, by deleting the older folders when backup disks are full.
• Detailed report per virtual machine (speed, space provisioning, times taken, etc...)
• Detailed log of every ESXi backup session.

XSIBackup is compatible with the following guest OS:

XSIBackup can backup any Operating System that is able to run in VMWare ESXi.

Compatibility depends mainly in the availability of ©VMWare Tools for the guest Operating System, if you want to perform hot backups with service quiescing.

Should ©VMWare Tools not be available for your OS, different options are available to still be able to perform hot backups: stopping services through a script or using warm or cold backup types.

In case of Linux Operating Systems, Open VM Tools service, which is an open source variant of VMWare Tools, is highly recommended.
