Truck based replication, also known as disk shipping, is a means of preseeding a remote site with data to be replicated, by physically shipping storage media to the remote site. This is particularly suited for situations where
In such situations, without truck based replication, DRBD would require a very long initial device synchronization (on the order of days or weeks). Truck based replication allows us to ship a data seed to the remote site, and drastically reduce the initial synchronization time. See Section 5.6, “Using truck based replication” for details on this use case.
