Simple backupscript utilizing rsync and hardlinks

Synopsis

Backup remote machines using ssh and rsync, utilizing hardlinks for files that has not changed since last backup

Configuration

BACKUPUSER=backup
BASEDIR=/backup/
CONFDIR=/usr/local/etc/backup
DIR="/etc /usr/local/etc"

setting	description
backupuser	is the user rsync users to connect to the remote machine, change this to the user you want to use
basedir	is the directory your backups are stored in. A file hieracy will be created here /{basedir}/{servername}/{date}/{directory}
confdir	is the directory with local configuration files (excludes and per-host configuration)
dir	default directories to backup - this can be changed on a per-host or hostgroup basis

For per-host configuration you need to create hostconf.sh in $CONFDIR (default is /usr/local/etc/backup/hostconf.sh)

This file needs a host_conf function which will be called with the hostname as an option backup script will run fine without this initial configuration

example:

host_conf()
{
case ${1} in
 web*)
  DIR="${DIR} /usr/local/www"
  HOSTGROUP="web freebsd denmark"
 ;;
esac
}

Furthermore the system looks for exclude files named: exclude.default exclude.servername exclude.hostgroup

using the above example and a hostname of web01.example.org, the following files would be included (if they exist):

exclude.default
exclude.web01.example.org
exclude.web
exclude.freebsd
exclude.denmark

note: if you specify DEFAULT_EXCLUDE=0 for a host, exclude.default will not be loaded.

These files need to hold regex or fullname of files to exclude example:

*.zip
*.t[gb]z
*.flv

or look at my example files: hostconf.sh exclude.default exclude.web exclude.mysql Hint: you can use zfs (or another file system with compression enabled) to have your easily compressed files etc compressed on-the-fly

Syntax

$path/backup.sh host1 host2 host3
