# ==========================================================
# Description:
# View, create, edit, enable/disable, delete and run on-demand
# the PVE backup jobs normally found under
#   Datacenter > Backup
# This is a thin wrapper around the official `pvesh` API
# (/cluster/backup), so jobs created/edited here show up exactly
# the same in the native PVE web UI and vice versa.
