UrBackup is an easy to setup Open Source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time.

Urbackup一个针对文件及系统镜像做备份的开源工具，完全及增量常规的备份方式都支持，且还提供WebUI管理。

服务端通过docker快捷部署

通过数据卷，将UrBackup的备份目录和数据库目录挂载到本地目录下，在下载urbackup镜像前，要在本地创建需要映射数据卷的目录，如/media/backups和/media/database，在/media/backups中将保存实际备份数据

docker run -d --name urbackup-server-1 -v /media/backups:/backups -v /media/database:/var/urbackup -p 55413-55415:55413-55415 -p 35623:35623/udp uroni/urbackup-server

客户端安装

在web管理页面上添加client，将自动提示跳转到client安装页面，可选择不同平台的安装，支持windows，MacOS，Linux

在下载安装完客户端后，客户端进程将自动启动，无需再手动启动一次，通过查看socket可以看到urbackupclient

netstat -antlp | grep urbackup
tcp        0      0 0.0.0.0:35621               0.0.0.0:*                   LISTEN      12504/urbackupclien 
tcp        0      0 0.0.0.0:35623               0.0.0.0:*                   LISTEN      12504/urbackupclien

在dnsmasq服务器上对osts文件备份,这里指定备份路径

urbackupclientctl add-backupdir -d /etc/hosts

查看当前urbackupclient的状态

urbackupclientctl status{"capability_bits": 65536,"finished_processes": [{"process_id": 1,"success": true}],"internet_connected": false,"internet_status": "no_server","last_backup_time": 1564998502,"running_processes": [],"servers": [{"internet_connection": false,"name": "10.x.x.60"}],"time_since_last_lan_connection": 23751}

查看备份目录路径

urbackupclientctl list-backupdirs
PATH       NAME  FLAGS

在客户端上执行完全备份

urbackupclientctl start -f
Waiting for server to start backup... done

进入容器，在服务端查看log，确认备份已成功
