# Script allows to cleanup target machine's DML DB from foreign archives and backups
#
# Requirements:
#    - Installed Acronis Cyber Protection agent
#    - Running of the script requires admin rights
#
# Notes:
#    By default script 
#      - Will be running in report mode, to display statistics related to archives and backups that are bounded to a machine
#      - Uses agent's DML database, so script will try to stop MMS service first, apply required actions, then start MMS
#        override path with --db-path option (or -d), in that case MMS service will not be touched
#      - Uses machine ID's from registry, override it with --machine-id option (or -m)
#      - Cleanup mode is turned off, override it with --cleanup option (or -c)

# To run script in report mode for current machine
