rsync + cron

Miten pääsen editoimaan mokomia, jotta saisin seuraavan löytämäni backup- skriptin toimimaan:

backup to a central backup server with 7 day incremental


#!/bin/sh

# This script does personal backups to a rsync backup server. 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"
# [email protected]

# directory to backup
BDIR=/home/$USER

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

# the name of the backup machine
BSERVER=owl

# your password on the backup server
export RSYNC_PASSWORD=XXXXXX

BACKUPDIR=`date %A`

export PATH=$PATH:/bin:/usr/bin:/usr/local/bin

# the following line clears the last weeks incremental directory
[ -d $HOME/emptydir ] || mkdir $HOME/emptydir
rsync --delete -a $HOME/emptydir/ $BSERVER::$USER/$BACKUPDIR/
rmdir $HOME/emptydir

# now the actual transfer
rsync $OPTS $BDIR $BSERVER::$USER/current
