usage="$(basename "$0") [--dir] [--force_period] - plugin for check backups according to config plan using bkp list.

params:
    --dir           - configs location ( default: /etc/opt/bkp )
    --force_period  - d,w,m - daily,weekly or montly
                      tells that last backup must be not older then period + 1 day
example:
    check_bkp --dir /etc/opt/bkp/solusvm --force_period w"
