Title (EN) PROVIDING A SNAPSHOT OF A SUBSET OF A FILE SYSTEM
(FR) INSTANTANE D'UN SOUS-ENSEMBLE D'UN SYSTEME DE FICHIERS
Abstract:
(EN) A system, method and computer readable medium for providing a snapshot of a subset of a file system. A first snapshot of a first set of source files in a file system is generated. The first snapshot includes an inode corresponding to each source file in the first set of files. Stored in each inode is a first identifier associated with the first set of files and a second identifier associated with the time of the first snapshot. Next, a second snapshot of a second set of source files is taken. The second snapshot includes an inode corresponding to each source file in the second set of files. Stored in each inode are a first identifier and a second identifier. Subsequent snapshots are taken every first period and every second period for the first set of files and the second set of files, respectively.
(FR) L'invention concerne un système, un procédé et un support lisible par un ordinateur, permettant d'obtenir un instantané d'un sous-ensemble d'un système de fichiers. Ce procédé consiste à produire un premier instantané d'un premier ensemble de fichiers source d'un système de fichiers. Le premier instantané comprend un inode correspondant à chaque fichier source du premier ensemble de fichiers. Chaque inode renferme un premier identificateur associé au premier ensemble de fichiers et un second identificateur associé à l'heure du premier instantané. Le procédé consiste ensuite à produire un second instantané d'un second ensemble de fichiers source. Le second instantané comprend un inode correspondant à chaque fichier source du second ensemble de fichiers. Chaque inode renferme un premier identificateur et un second identificateur. Les instantanés suivants sont produits à chaque première période et à chaque seconde période pour le premier ensemble de fichiers et le second ensemble de fichiers, respectivement.
