FIELD: information technology.
SUBSTANCE: method involves sending to a virtual machine a request to create an application-coordinated snapshot of the virtual machine volume of said virtual machine, wherein the virtual machine is configured to create said application-coordinated snapshot while the virtual machine is being run; reception of the signal which indicates that the virtual machine has created an application-coordinated snapshot of the virtual machine volume; creating a snapshot of the host volume, wherein the virtual machine volume is stored as a file at the host; and extracting the application-coordinated snapshot of the virtual machine volume from the snapshot of the host volume.
EFFECT: efficient creation of application-coordinated backup copies without initial interruption or switching off of the virtual machine.
