We[^1] optimized the migration of a 120GB disk with 50% used data from roughly eight to about one minute. This could be accomplished by replacing the former solution mbuffer with our selfmade one. A HTTP server/client simplifies the connection handling by natively supporting encryption via TLS such as parallelity via concurrent connections. As our local storage is a thin provisioned lv, we could use a block map to only transfer used data.
