Method and system for backup and recovery

An system for data backup and recovery based on linked file repositories, wherein the system includes at least one of:

• at least one server system;
• the linked file repositories, wherein each of the linked file repositories representing an individual file system capable of storing at least one version of a file, and in communication with the at least one server system;
• and
• at least one processor device, in communication with each the linked file repositories and the at least one server system, operable in the system, wherein the at least one processor device:
• places each of the linked file repositories in one of a plurality of positions for storing the at least one version of the file,
• continuously numbers each of the plurality of positions of each of the linked file repositories,
• determines a number of the at least one version of the file by the one of a plurality of positions of the one of the linked file repositories, and
• implements a version-recovery process over each of the linked file repositories to perform a read operation of the at least one version of the file.

A computer program product of data backup and recovery based on linked file repositories with each of the linked file repositories representing an individual file system capable of storing at least one version of a file and being connected to at least one server system, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

• a first executable portion that places each of the linked file repositories in one of a plurality of positions for storing the at least one version of the file;
• a second executable portion that continuously numbers each of the plurality of positions of each of the linked file repositories;
• a third executable portion that determines a number of the at least one version of the file by the one of a plurality of positions of the one of the linked file repositories;
• and
• a fourth executable portion that implements a version-movement process over each of the linked file repositories to perform a read operation of the at least one version of the file.
