Title
(EN) SYSTEMS AND METHODS FOR ALLOWING INCREMENTAL JOURNALING
(FR) SYSTÈMES ET PROCÉDÉS PERMETTANT UNE JOURNALISATION INCRÉMENTIELLE
Abstract
(EN)
In one embodiment, systems and methods are provided for incremental journaling. In one embodiment, order-independent operations are journaled incrementally for the same storage location. In one embodiment, partially ordered operations are journaled incrementally for the same storage location. In one embodiment, order-independent operations and partially ordered operations are journaled incrementally for the same storage location. In one embodiment, incremental journaling is used to update data that represents accounting, ctime, and parity.

Dans un de ses modes de réalisation, l'invention concerne des systèmes et des procédés permettant une journalisation incrémentielle. Dans un mode de réalisation de l'invention, des opérations ne dépendant pas d'un ordre donné sont journalisées de manière incrémentielle pour le même emplacement de stockage. Dans un mode de réalisation de l'invention, des opérations partiellement ordonnées sont journalisées de manière incrémentielle pour le même emplacement de stockage. Dans un mode de réalisation, des opérations ne dépendant pas d'un ordre donné et des opérations partiellement ordonnées sont journalisées de manière incrémentielle pour le même emplacement de stockage. Dans un mode de réalisation, une journalisation incrémentielle est utilisée pour mettre à jour des données représentant une comptabilité, le temps (ctime) et la parité.
