Avhd files and it will take up much storage space if you create multiple snapshots. Snapshots (or restore points) can capture state, data and hardware configuration of a running virtual machine, so you can quickly and conveniently restore virtual machine to its previous state. If you want to learn more methods, please refer to this virtual machine backup guide. Here I'll focus on a Guest-level backup method - it may be more economical in smaller virtual environments. Guest-level backup, on the other hand, protects files and applications by treating the virtual machine as physical assets.īoth of these forms have their advantages and disadvantages. Host-level backup works at the hypervisor level and backs up entire VMs, including their configurations, making management and recovery easier. Guest-level backup is similar to physical machine backup and requires an agent to be installed on each VM, but it allows you to select what to back up specifically, such as individual files. Host-level vs Guest-level Virtual Machine Backupīackup is a very broad concept, and when it comes to virtual machine backups, we can generally divide them into host-level backup and guest-level backup (or image-based backup and file-based backup). Simply put, host-level backup captures files, application data and virtual hardware.

Best Practices to Backup Virtual Machine for Free.Is VM Snapshot Equivalent to VM Backup?.Host-level vs Guest-level Virtual Machine Backup.Reduce business downtime. A fast and reliable disaster recovery solution is essential for your business. If your virtual machine is unavailable and cannot be recovered in the short term, the business loss could be incalculable. Suppose you have hundreds of virtual machines but never backed up your virtual machines, your loss will be immeasurable in case of system crash or other accidents such as virus attack, disk failure, hardware failure, etc.

Here are two main reasons:Īvoid critical data loss. And as the number of server virtualization grows, backing up virtual machines has become an increasingly important issue. Virtual machine provides customers a complete operating system based on virtual hardware, which is similar to physical computers.
