企业级的开源备份工具之磁盘柜存储配置

一、iscsi网络存储

1.1 配置FreeNAS

考虑专业的磁盘柜价格不菲，而使用服务器的方式一方面磁盘容量有限，另一方面IO的性能也很难保障。FreeNAS是一套免费的NAS服务器，它能将一部普通PC变成网络存储服务器。用户可通过Windows、Macs、FTP、SSH 及网络文件系统 (NFS) 来访问存储服务器。

我们通过它来组建符合企业使用的备份存储设备，该系统具体的安装步骤可参考相关资源。这里通过启用iscsi功能实现网络备份存储，相关设置如下图。

1.2 配置iscsi客户端

iSCSI的服务器端已经在FreeNAS上完成配置，接下来需要在linux系统上完成客户端的配置，实现在客户端对网络存储的挂载。

首先安装相关的系统组件并完成配置文件的修改。

yum -y install iscsi-initiator-utils  vi /etc/iscsi/initiatorname.iscsi  InitiatorName=iqn.2016-06.com.redhat:82367514497d#客户端的标记

接下来修改主要的配置文件。

vi /etc/iscsi/iscsid.conf

node.session.auth.authmethod = CHAP#根据freenas的设置修改 node.session.auth.username = myj.5.199 node.session.auth.password = testtesttest discovery.sendtargets.auth.authmethod = CHAP#根据freenas的设置修改 discovery.sendtargets.auth.username = backup.myj discovery.sendtargets.auth.password = testtesttest

完成设置后通过以下指令查看配置和连接情况。

iscsiadm -m discovery -t sendtargets -p 192.168.5.199 iscsiadm -m node -o show

1.3 配置开机自动挂载

完成iSCSI的配置后，接下来配置开机自动挂载及相应的服务自动启动设定，具体系统分区操作略。

systemctl enable iscsid.service iscsiadm -m node -T iqn.2005-10.org.freenas.ctl:backu-10ttarget -p 192.168.5.199 --op update -n node.startup -v automatic Ls -l /dev/disk/by-uuid Blkid /dev/sdc1

二、备份存储设置

2.1 配置bacula-dir.conf

JobDefs {   Name = "DefaultJob"   Type = Backup   Level = Incremental   Client = bak-192.168.0.97   FileSet = "Windows"   Schedule = "WeeklyCycle"   Storage = windows-file   Messages = Standard   Pool = Default   Full Backup Pool = full-pool   Incremental Backup Pool = inc-pool   Differential Backup Pool = diff-pool   SpoolAttributes = yes   Priority = 10   Write Bootstrap = "/var/spool/bacula/%h.bsr" } Job {   Name = "bak-192.168.0.97"   JobDefs = "DefaultJob" } Job{   Name = "bak-192.168.5.86"   Type = Backup   Level = Incremental   Client = bacula-fd   FileSet = "Bacula Set"   Schedule = "WeeklyCycle"   Storage = linux-file   Messages = Standard   Pool = Default   Full Backup Pool = full-pool   Incremental Backup Pool = inc-pool   Differential Backup Pool = diff-pool   SpoolAttributes = yes   Priority = 10   Write Bootstrap = "/var/spool/bacula/%h.bsr" } Job {   Name = "BackupCatalog"   JobDefs = "DefaultJob"   Level = Full   FileSet="Catalog"   Schedule = "WeeklyCycleAfterBackup"   # This creates an ASCII copy of the catalog   # Arguments to make_catalog_backup.pl are:   #  make_catalog_backup.pl <catalog-name>   RunBeforeJob = "/usr/libexec/bacula/make_catalog_backup.pl MyCatalog"   # This deletes the copy of the catalog   RunAfterJob  = "/usr/libexec/bacula/delete_catalog_backup"   Write Bootstrap = "/var/spool/bacula/%n.bsr"   Priority = 11                   # run after main backup } Job {   Name = "RestoreFiles"   Type = Restore   Client=bacula-fd   FileSet="Bacula Set"   Storage = linux-file   Pool = Default   Full Backup Pool = full-pool   Incremental Backup Pool = inc-pool   Differential Backup Pool = diff-pool   Messages = Standard   Where = /tmp/bacula-restores } FileSet {   Name = "Windows"   Include {     Options {       signature = MD5       compression = GZIP       IgnoreCase = yes     }     File = "e:/datatbak"   } } FileSet {   Name = "Bacula Set"   Include {     Options {       signature = MD5       Compression = GZIP     }     File = /var/lib/mysql   }   Exclude {     File = /var/spool/bacula     File = /tmp     File = /proc     File = /tmp     File = /sys     File = /.journal     File = /.fsck   } } Schedule {   Name = "WeeklyCycle"   Run = Full 1st sun at 23:05   Run = Differential 2nd-5th sun at 23:05   Run = Incremental mon-sat at 23:05 } Schedule {   Name = "WeeklyCycleAfterBackup"   Run = Full sun-sat at 23:10 } FileSet {   Name = "Catalog"   Include {     Options {       signature = MD5     }     File = "/var/spool/bacula/bacula.sql"   } } Client {   Name = bak-192.168.0.97   Address = 192.168.0.97   FDPort = 9102   Catalog = MyCatalog   Password = "IYN0eZTw2BrRcA/MNGCwGHb9OrHDRykMMF8jSxtA7zUF"          # password for FileDaemon   File Retention = 15 days            # 60 days   Job Retention = 1 months            # six months   AutoPrune = yes                     # Prune expired Jobs/Files } Storage {   Name = windows-file # Do not use "localhost" here   Address = 192.168.5.86                # N.B.

2.2 配置bacula-sd.conf

Device {   Name = FileChgr-windows   Media Type = File   Archive Device = /backup/windows   LabelMedia = yes;                   # lets Bacula label unlabeled media   Random Access = Yes;   AutomaticMount = yes;               # when device opened, read it   RemovableMedia = no;   AlwaysOpen = no;   Maximum Concurrent Jobs = 5 } Device {   Name = FileChgr-linux   Media Type = File   Archive Device = /backup/linux   LabelMedia = yes;                   # lets Bacula label unlabeled media   Random Access = Yes;   AutomaticMount = yes;               # when device opened, read it   RemovableMedia = no;   AlwaysOpen = no;   Maximum Concurrent Jobs = 5 }

三、图形界面配置

bacula默认的安装是字符界面（其实也有基于QT环境的GUI界面，考虑性能和所依赖的安装包太多，没有使用）。第三方的工具有基于WEB的界面报告，基本上可以满足日常需要。

3.1 安装相关组件

yum install httpd php php-gd php-gettext php-mysql php-pdo systemctl enable httpd.service systemctl start httpd.service firewall-cmd --permanent --add-port=80/tcp firewall-cmd --reload cd /var/www/html curl -O http://www.bacula-web.org/files/bacula-web.org/downloads/bacula-web-latest.tgz mkdir -v /var/www/html/bacula tar -xzf bacula-web-latest.tgz -C /var/www/html/bacula chown -Rv apache: /var/www/html/bacula cd application/config cp -v config.php.sample config.php chown -v apache: config.php

3.2 配置文件

vi config.php

$config['language'] = 'en_EN'; $config[0]['label'] = 'Backup Server'; $config[0]['host'] = 'localhost'; $config[0]['login'] = 'bacula'; $config[0]['password'] = 'verystrongpassword'; $config[0]['db_name'] = 'bacula'; $config[0]['db_type'] = 'mysql'; $config[0]['db_port'] = '3306';

vi /etc/php.ini

date.timezone = Asia/Shanghai vim /etc/httpd/conf.d/bacula.conf
