SimpleDirBackup

From RdiffBackupWiki

A very simple script to backup a directory (in this case, a CVS repository) to another partition in the filesystem. Some parts based on TroelsScript

#!/bin/bash
# simple_backup.sh: a very simple script to backup CVS repository to another partition
# I added this script to cron:
# 35 13 * * *  /etc/simple_backup.sh &> /var/log/bkp/`date +%m%d-%H%M`.log

# -------------
# CONFIG
# -------------

TIMESTAMP=`date +%m%d_%H%M`

# Backup Destination is a mounted partition on /backup
DST="/backup/cvs"

# The disk where this partition is located
DISK="/dev/hdb4"

# The directory to backup
SRC="/opt/cvsrepository"

# How long to keep backup history
# In this case, the user can recover the backup state as it was 9 months ago (maxage)
MAXAGE="9M"

# Path to rdiff-backup binary
RDIFF="/usr/bin/rdiff-backup"

# Log file directory - needs to be created
LOG="/var/log/bkp"

# Some basic configuration options; see the manual
OPTIONS="--print-statistics --no-change-dir-inc-perms"
