ftpsync-cron  is part of the ftpsync suite for mirroring Debian and Debian-like repositories of packages.
       As there are way too many mirrors of Debian to populate them all from  the  machine  that  generates  the
       archive (“ftp-master”), mirrors are organized in a tree-shaped hierarchy.  Thus, every mirror has exactly
       one  upstream  from which it syncs, and each mirror can have any number of downstreams which in turn sync
       from it.

       ftpsync-cron is a wrapper around ftpsync itself, intended to be run out of cron at regular, frequent  in‐
       tervals,  such  as  hourly.  When started, it reads the corresponding ftpsync.conf configuration file for
       the archive in question and determines this mirror’s upstream.  It then fetches the upstream’s trace file
       via HTTP and compares it to the version on disk from the last mirror run, thus learning whether  the  up‐
       stream mirror has updated.  If it has, ftpsync is triggered.

       Example use in a user crontab:

       SHELL=/bin/bash 31 * * * * sleep $(( RANDOM %% 1800 )) && ./bin/ftpsync-cron
