Abstract
Methods and apparatus for updating virtual machines (VMs) on a provider network according to modifications made to a server in a client network. A version of the server may be currently instantiated and executing as one or more VM instances on the provider network. Agent(s) installed on the server in the client network intercept write requests to volume(s) attached to the server, and send blocks that include updates to the server volume(s) to a service on the provider network. The service stores the blocks to incremental snapshots, and generates timestamped machine images (MIs) of the server from the snapshots. A VM service updates the VM instances on the provider network according to the MIs. Thus, the VM instances can be kept up to date with changes to the server without having to upload the entire volume(s) to the provider network to perform each update.
