リモートバックアップ

ローカルディスクへの１日に１回のフルバックアップと、 １時間に１回の差分バックアップは出来たが、
それだけではディスクがクラッシュしてしまうと復元できない。
リモートマシンへバックアップを取る。

rsync サーバの設定

/etc/rsyncd.conf の設定

root@xhl:~# vi /etc/rsyncd.conf
	:
	:
root@xhl:~# cat !$
cat /etc/rsyncd.conf
[Backup]
        path = /mnt/Backup
        hosts allow = 192.168.1.0/24 192.168.2.0/24
[httpd]
        path = /home/httpd
        hosts allow = 192.168.1.0/24 192.168.2.0/24
root@xhl:~#

/etc/inetd.conf の設定

root@xhl:~# grep rsync /etc/inetd.conf
root@xhl:~# mv /etc/inetd.conf{,.orig}
root@xhl:~# cp /etc/inetd.conf{.orig,}
root@xhl:~# echo "rsync   stream  tcp     nowait  root    /usr/sbin/tcpd /usr/bin/rsync --daemon" >> /etc/inetd.conf
root@xhl:~#

inetd.conf の再読み込み

root@xhl:~# kill -HUP `cat /var/run/inetd.pid `
root@xhl:~#

rsync クライアント？の設定
