在确保用户信息一致的情况下(否则在新机器上会显示用户的UID, GID)

sudo rsync -av /home bigMem1:/home

备份 (must be in root to preserve permissions).

You should start many rsync processes syncing different parts to speed up.

Only use -z compression option if you are in low bandwith.

Use sudo restorecon -r -p / to reset all security contexts (for SELinux).

So sshd will be able to read .ssh/authorized_keys when running as service.

在web0上定期备份loginNode:/home

在web0上的/mnt/loginNode/home以read only方式挂载了loginNode:/home, 使用了rsnapshot进行备份(yum安装)

参考文档: https://github.com/rsnapshot/rsnapshot

几乎所有的配置都在/etc/rsnapshot.conf中.

更新计划根据conf文件写入了crontab中:
