目标：每日备份一次，然后上传至另外的服务器。
一、简单备份脚本
/home/tools/backup.sh：
/usr/bin/rm /var/opt/gitlab/backups/* -rf
/opt/gitlab/bin/gitlab-rake gitlab:backup:create
/usr/bin/scp /var/opt/gitlab/backups/* root@192.168.3.179:/home/backups/gitlabs
/usr/bin/scp /etc/gitlab/gitlab.rb root@192.168.3.179:/home/backups/gitlabs/gitlab.rd.`date +%Y-%m-%d.%k%M%S`.rd
ssh root@192.168.3.179 find '/home/backups/gitlabs/' -mtime +3 -type f -exec 'rm -f {} \;'
二、定时任务
[root]# crontab -l 0 1 * * * /usr/bin/bash /home/tools/backup.sh
