# Sample script template for setting up a Mageia mirror server.
#
# This script does the minimum tasks to rsync your local mirror
# from a Mageia source mirror.
#
# For that, please:
#  * define LOCAL_MIRROR and SOURCE_MIRROR vars;
#  * ideally, run this script every two hours for a public mirror.
#
# As soon as your mirror is ready, make sure to register it in our mirrors
# database on http://mirrors.mageia.org/new .
#
# For more information, see http://mirrors.mageia.org/ or join
# irc://irc.freenode.net/#mageia-sysadm
#

# Path to your local mirror repository.
# You will need to dedicate about 700 GB.
#
LOCAL_MIRROR=

# Remote rsync server you are using.
#
#  * if your mirror is public, please use one of our Tier1 mirrors, listed on
#    http://mirrors.mageia.org/?tier1
#
#  * if your mirror is for private/internal use, please use one of the Tier2
#    mirrors, listed on http://mirrors.mageia.org/?tier2
#
SOURCE_MIRROR=

#
RSYNC=`which rsync`

# Please at least use the following options:
# --archive / -a (needed)
# --hard-links / -H (needed)
# --spare / -S (nice to have)
# --delete-after (nice to have)
#
# Please do not use compression and checksum options, to not overload
# remote server.
#
OPTIONS="-aHS --delete-after"
