BOS is a backup and restoring application installed on a dedicated server. The server is present in the network and accessing every object you want to backup according to a defined schedule. The access and backup operation is performed in the simplest possible way: without any agents involved, any special hardware required and any noticeable interruption to the system functions. It uses the local hard drive as backup media. It manages the backed up files and data in one single folder. This folder contains the network structure (machines), folders and files of each machine, each file's different versions, and also the BOS (patent pending) tiny and unique database.
