Replication Setup

Before you set up the D2D for replication it is important to understand the concept of slot mapping,
because this is how replication is administered. It is also important to understand your cartridge
rotation scheme because the replication is all predicated on knowing that weekly backups go to Tape
X in Slot Y, that daily incrementals go to Tape A in Slot B and so on. Replication is triggered by a
tape being ejected from a virtual tape drive in the D2D. HP D2D replication ensures than minimum
bandwidth is used for incremental backups being replicated from the same tape, by only transferring
the incremental manifests associated with each "session" of incremental backups appended to the
same tape.
