Abstract
The project entitled ËœHierarchical data backupâ„¢ aims to design and develop a system for the reliable backup of the critical data. The current backup strategies for data backup are based on direct attached storage methods, in which we backup our data in a hard disk attached directly to dedicated centralized server. Our project aims to develop a more reliable, secure and dependable backup scheme based on a distributed and hierarchical storage of data. The project develops a system in which the data to be backed up is stored in a set of nodes in a LAN rather than in a single node or server, providing a distributed backup mechanism, extending this backup to provide a more reliable storage through an external storage device and to develop a protocol for the hierarchical backup of the data over the intranet through the introduction of the external storage device.
