Recovery from system data deduplication can be slower than modern tape drives, and restores from other systems of deduplication can be faster tape could ever dream de.Dans this topic, you learn what you need to do to ensure your system de-duplication is located on the right side of these two extremes.
To explain why there are that many call a "de-duplication fee", we need to go back in time to when there is was no data de-duplication technology.Before de-duplication, we wrote data to tape or disk block contiguous .(Écrire_deles_de_blocs_contigus_de_données_de_sauvegarde_sur_disque_nécessite_un_système_de_fichiers_vide_ou_un_système_de_disque_conçu_à_cet_effet,_comme_une_librairie_de_bandes_virtuelle).All blocks containing a given backup were located near each other.
Backup data may also perform a full backup, a synthetic full backup, or otherwise colocaliser files needed for full recovery (for example, active IBM TSM data pools) .these behaviors typical of backup systems meant that much needed to restore a system blocks would all be placed contiguously on disk or tape, do a restore full of this very easy to implement System.
