Backup script using rsync

# Taken from http://samba.anu.edu.au/rsync/examples.html

# This script does personal backups.  You will end up with a 7 day 
# rotating incremental backup.  The incrementals will go into 
# subdirectories named after the day of the week, and the
# current full backup goes into a directory called "current".

# directory to backup
BDIR=$HOME

# excludes file - this contains a wildcard pattern per line of files
# to exclude
EXCLUDES=$HOME/local/etc/backup_exclude

# the backup location
BLOCATION=/Volumes/Storage/Backups

# set to the location of directory containing additional
# backup scripts to be run prior to backing up
SCRIPTS_DIR=$HOME/local/etc/backup.d
