NAME

       ftpsync-cron - Wrapper around ftpsync for use in cron(8)

SYNOPSIS

       ftpsync-cron [ARCHIVE]

DESCRIPTION

       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
       intervals, 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
       upstream mirror has updated.  If it has, ftpsync is triggered.

EXAMPLE

       Example use in a user crontab:

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