Title
(EN) RESTORING A DATABASE USING A FULLY HYDRATED BACKUP
(FR) RESTAURATION D'UNE BASE DE DONNÉES À L'AIDE D'UNE SAUVEGARDE ENTIÈREMENT HYDRATÉE
Abstract
(EN)
A backup of a database is determined to be performed. A backup of at least a portion of contents of a storage volume that includes data of the database is performed. The backup includes a step of creating a new metadata tree root node. Creating the new metadata tree root node includes copying from another metadata tree root node of a tree data structure corresponding to a previous backup instance, one or more references to one or more lower tier metadata tree nodes associated with the tree data structure corresponding to the previous backup instance.

Selon la présente invention, il est déterminé d'effectuer une sauvegarde d'une base de données. Une sauvegarde d'au moins une partie du contenu d'un volume de mémoire qui comprend des données de la base de données est effectuée. La sauvegarde comprend une étape de création d'un nouveau nœud-racine d'arborescence de métadonnées. La création du nouveau nœud-racine d'arborescence de métadonnées consiste à copier, à partir d'un autre nœud-racine d'arborescence de métadonnées, une structure de données arborescente correspondant à une instance de sauvegarde précédente, une ou plusieurs références à un ou plusieurs nœuds d'arborescence de métadonnées de niveau inférieur associés à la structure de données arborescente correspondant à l'instance de sauvegarde précédente.
