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