An improved method for backup and recovery based on linked file repositories (210, 212, 214), each representing an own file system capable of storing one version of a file and being connected to a least one server system (102) is claimed; wherein each file repository (210, 212, 214) is placed in a certain position storing a certain version of said file; wherein positions of said file repositories (210, 212, 214) are continuously numbered; wherein a number of the certain version of the file is determined by the position of said corresponding file repository (210, 212, 214); wherein a version-movement process over all file repositories (210, 212, 214) is implemented to perform a file write operation; and wherein a version-recovery process over all file repositories (210, 212, 214) is implemented to perform a file-read operation of a certain file version. |
