Techniques disclosed herein provide an approach for creating snapshots and reverting to the same for virtual machine (VM) guest operating systems (OSes). In one embodiment, a snapshot module in a guest OS receives blocks for a snapshot of a guest OS volume. In turn, the snapshot module creates a snapshot file in a repository external to a virtual disk of the VM, and writes the received blocks to the external repository. By storing snapshot content outside the virtual disks of VMs, disk space limitations in local VM disks can be overcome, and it is also more difficult for malicious software to modify the snapshots and infect them. To reduce storage space requirements, snapshots stored in the external repository may be deduplicated with other snapshots stored therein, including snapshots from guest OSes running in other VMs and/or a host OS on which a hosted hypervisor runs.
A method of creating a snapshot of a guest operating system (OS) volume, the guest OS running in a virtual machine (VM) on top of a hypervisor, the method comprising:
A non-transitory computer-readable storage medium containing a program which, when executed by one or more processors, performs operations for creating a snapshot of a guest operating system (OS) volume, the guest OS running in a virtual machine (VM) on top of a hypervisor, the operations comprising:
A system, comprising:
