This feature is called Granular Backup and an example setup is found here.Īnother great characteristic of Granular Backup is that there is no need to create a network share to access VM-internal files from the outside. The backup runs on the host and files are read directly from a consistent view of the VM’s hard drives, without the VM being aware of the process and without any interference. In other words, if the virtual machine contained a virus or ransomware, it will not affect the host because the host will never get into contact with contaminated files.īecause BackupChain doesn’t mount the VM’s hard drive, there is no way for the Windows operating system on the host to automatically start any executable code that may be infected inside the VM. Unlike other technologies, however, BackupChain does not mount the virtual disk contents to the host system. Through a unique feature in our server backup solution, it’s possible in BackupChain to back up folders and files from the host that are stored inside the VM. Unfortunately this is not a secure method because an infected VM may infect the host server and thereby gain access to the host’s internal system and LAN. Are you wondering whether secure virtual machine file backup is possible and what can be done to protect against viruses and ransomware? Many backup solutions use a risky method to access VM files, namely direct mounting of the VM’s disks to the host server.
