Features

Bacula Enterprise is an especially secure, scalable and modular backup and recovery software solution with a wide range of capabilities. Backup up KVM hypervisor(s) and its data in a comprehensive manner is one of its many qualities.

Bacula System’s KVM Module is fast, reliable, especially simple to use and establishes confidence in the backup system administrator.

The Bacula Enterprise KVM Plugin provides the following main features:

Automatic virtual machine discovery
File level backup of virtual machines
Full, Differential, and Incremental backup level support
The ability to handle inclusion/exclusion of files
Backup of virtual machines in a ’running’, ’paused’ or ’shut off’ state

KVM enables Linux to do the system grunt work, so it can focus on handling new virtualization instructions exposed by the hardware. Another key benefit for KVM is that it inherits any continuing system improvement from upstream in the larger Linux community.

It is crucial that the kernel modules do not emulate the virtual machine hardware that the guest OS runs on. KVM uses QEMU to build the virtual machines (VM) that interact with guest OS. Each VM is a regular Linux process, which means familiar Linux commands like ‘top’ and ‘kill’ can be used to manage and monitor the VMs.

KVM transforms Linux into a type 1 hypervisor, also known as a bare-metal hypervisor. Type 1 hypervisors directly access the computer’s hardware and replace the host OS. They are also considered secure because there is nothing between a hypervisor and a CPU that a potential attacker could tamper with. As part of the Linux kernel, KVM has all the OS-level components. This means that each VM works like a regular Linux process and has dedicated virtual components like memory, disks, CPU and network card.

Bacula Enterprise data backup and recovery allows you to back up not only KVM environments, but covers your entire IT estate through a single plane of glass. It brings unprecedented levels of security, business value benefits and low cost of ownership.
