五、恢復(fù)

假定我們需要恢復(fù)cp3上一些丟失的數(shù)據(jù)，首先用amandabackup帳號(hào)登錄cp2機(jī)器，創(chuàng)建/etc/amanda/amanda-client.conf文件，內(nèi)容如下：

#

# amanda.conf - sample Amanda client configuration file.

#

# This file normally goes in /etc/amanda/amanda-client.conf.

#

conf "FileBackup"# your config name

index_server "cp1.domain.com"# your amindexd server

tape_server "cp1.domain.com"# your amidxtaped server

#tapedev "tape:/dev/YOUR-TAPE-DEVICE-HERE"# your tape device

# if not set, Use configure or ask server.

# if set to empty string "", ask server

# amrecover will use the changer if set to the value

# of 'amrecover_changer' in the server amanda.conf.

# auth- authentication scheme to use between server and client.

# Valid values are "bsd", "bsdudp", "bsdtcp", "krb5", "local",

# "rsh" and "ssh".

# Default: [auth "bsdtcp"]

auth "bsdtcp"

#ssh_keys ""# your ssh keys file if you use ssh auth

然后使用root帳號(hào)運(yùn)行amrecover命令來(lái)初始化data恢復(fù)過(guò)程

[root@cp3 ~]# amrecover

AMRECOVER Version 2.6.1p1. Contacting server on cp1.domain.com ...

220 cp1 AMANDA index server (2.6.1p1) ready.

Setting restore date to today (2009-04-13)

200 Working date set to 2009-04-13.

200 Config set to FileBackup.

200 Dump host set to cp3.domain.com.

Use the setdisk command to choose dump disk to recover

amrecover>

接下的一些命令演示如何將特定的一些數(shù)據(jù)恢復(fù)到指定的目錄(這里指定/tmp)

amrecover> listdisk

200- List of disk for host cp3.domain.com

201- /opt/www/sites

200 List of disk for host cp3.domain.com

amrecover> setdisk /opt/www/sites

200 Disk set to /opt/www/sites.

amrecover> ls

......

我們看看/tmp下面是不是已經(jīng)有了我們剛才恢復(fù)的數(shù)據(jù)：

[root@cp3 ~]# tree /tmp/admin/domain.com/subdomains/ |more

/tmp/admin/domain.com/subdomains/

|-- 404

| |-- bin

| | |-- bash

| | |-- cat

| | |-- echo

| | |-- false

......

Ok,到此為止，Amanda備份配置基本完成，當(dāng)然我們很多的配置都是基于缺省定義，比如槽位數(shù)，備份周期等，更多詳細(xì)的定義，可以參考/usr/lib/amanda/example/amanda.conf文件。
