Abstract: front page image
(EN) The invention relates, in particular, to the replication of data between a source system and a destination system. After having calculated a signature for a fragment of data to be replicated, the source system transmits same to the destination system. The latter determines whether or not said signature is known, i.e. whether or not a fragment is associated with said signature. If so, the data to be replicated is reconstructed (with respect to fragment in question). If not, a message indicating that the signature is unknown is transmitted to the source system, which then transmits the corresponding fragment to the destination system. The latter stores and reconstructs the data to be replicated (with respect to the fragment in question).
(FR) L'invention a notamment pour objet la réplication de données entre un système source et un système destination. Après avoir calculé une signature d'un fragment de donnée à répliquer, le système source la transmet au système destination. Ce dernier détermine si cette signature est connue, c'est-à-dire si un fragment est associé à cette signature. Dans l'affirmative, la donnée à répliquer est reconstruite (vis-à-vis du fragment concerné). Dans le cas contraire, un message indiquant la signature inconnue est transmis au système source qui transmet alors le fragment correspondant au système destination. Ce dernier le mémorise et reconstruit la donnée à répliquer (vis-à-vis du fragment concerné).
