# Short-Description: backup and restore program
# Description:       Burp is a backup and restore program. It uses librsync in order to save onr
#                    the amount of space that is used by each backup. It also uses VSS (Volumer
#                    Shadow Copy Service) to make snapshots when backing up Windows computers.
