Abstract: An integrated circuit includes a host interface coupled to a host device executing a tenant operating system (OS) on bare metal and hardware accelerator(s) coupled to the host interface and a network interface. The hardware accelerator(s) receive, over the host interface, a snapshot request relating to a snapshot of tenant OS. Snapshot request includes a location, in a physical memory of the host device, of a swap file having contents of random access memory of the host device. The hardware accelerator(s) encrypt the swap file and initiate transfer of the encrypted swap file to a network storage device coupled to a cloud-based server. The hardware accelerator(s) send, over the network interface, to a snapshot manager hosted by the cloud-based server, metadata associated with storing the encrypted swap file in the cloud-based server, to allow the snapshot manager to manage the snapshot of the tenant OS.
