#
# A script to use rsync to push AIM CIPS data to Hampton University
#
# Expected arguments
# $1 the source directory on the local system
# $2 the target directory on the remote system

TARGET_SYSTEM=aim_cips@aim.hamptonu.edu

# Set the options for rsync
# -a archive -- preserve almost everything
# -r recursive -- copy directories recursively
# -v verbose -- information about what files are being transferred and a brief summary at the end
# -q, --quiet -- suppress non-error messages
# -u, --update -- skip files that are newer on the receiver
# -z compress -- compresses any data from the files that it sends to the destination machine
# -e -- specify the remote shell to use
# --chmod=a+rx -- change the file permissions at the receiving end as specified
# --exclude  *prelim* -- ignore preliminary data
# --exclude *backup* -- ignore backup files
# --delete-excluded -- delete any files on the receiving side that aren't on the sending side;
#    also delete any files on the receiving side that are excluded
# -timeout -- if no data is transferred within the specified time then rsync will exit
#   300 seconds is in this case a heuristically determined timeout
RSYNC_OPTIONS="-arzu --chmod=a+rx --progress --exclude *prelim* --exclude *backup* --timeout=300"
