一、iscsi網絡存儲
1.1 配置FreeNAS
考慮專業的磁盤櫃價格不菲，而使用服務器的方式一方面磁盤容量有限，另一方面IO的性能也很難保障。FreeNAS是一套免費的NAS服務器，它能將一部普通PC變成網絡存儲服務器。用戶可通過Windows、Macs、FTP、SSH 及網絡文件系統 (NFS) 來訪問存儲服務器。
我們通過它來組建符合企業使用的備份存儲設備，該系統具體的安裝步驟可參考相關資源。這裏通過啓用iscsi功能實現網絡備份存儲，相關設置如下圖。
1.2 配置iscsi客戶端
iSCSI的服務器端已經在FreeNAS上完成配置，接下來需要在linux系統上完成客戶端的配置，實現在客戶端對網絡存儲的掛載。
首先安裝相關的系統組件並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#客戶端的標記
接下來修改主要的配置文件。
vi /etc/iscsi/iscsid.conf
node.session.auth.authmethod = CHAP#根據freenas的設置修改 node.session.auth.username = myj.5.199 node.session.auth.password = testtesttest discovery.sendtargets.auth.authmethod = CHAP#根據freenas的設置修改 discovery.sendtargets.auth.username = backup.myj discovery.sendtargets.auth.password = testtesttest
完成設置後通過以下指令查看配置和連接情況。
iscsiadm -m discovery -t sendtargets -p 192.168.5.199 iscsiadm -m node -o show
1.3 配置開機自動掛載
完成iSCSI的配置後，接下來配置開機自動掛載及相應的服務自動啓動設定，具體系統分區操作略。
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

}三、圖形界面配置
bacula默認的安裝是字符界面（其實也有基於QT環境的GUI界面，考慮性能和所依賴的安裝包太多，沒有使用）。第三方的工具有基於WEB的界面報告，基本上可以滿足日常需要。
