<p><span style="font-size: large;">這幾天一直在玩一些備份用的工具，像是rsnapshot / dsnapshot / zfs-auto-snapshot等等</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">不過都不是很滿意，有的是設定不方便，有的是速度太慢，有的是沒有dedup功能</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">本來是已經打算就加硬碟，用ZFS當檔案系統來處理</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">後來看到有這個軟體 </span><a href="http://www.obnam.org" title="OBNAM Offical Website"><span style="font-size: large;">obnam</span></a></p>
|
|
|
|
|
|
<p><span style="font-size: large;">看起來似乎滿強的</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">官網的介紹如下</span>
|
|
|
> <span style="font-size: large;">Obnam is an <strong>easy, secure backup program.</strong> Backups can be stored on local hard disks, or online via the </span><a href="http://en.wikipedia.org/wiki/SSH_File_Transfer_Protocol"><span style="font-size: large;">SSH SFTP</span></a><span style="font-size: large;"> protocol. The backup server, if used, does not require any special software, on top of SSH.</span>
|
|
|
>
|
|
|
>
|
|
|
> <span style="font-size: large;">Some <strong>features</strong> that may interest you:</span>
|
|
|
>
|
|
|
>
|
|
|
> * <span style="font-size: large;"><strong>Snapshot</strong> backups. Every generation looks like a complete snapshot, so you don’t need to care about full versus incremental backups, or rotate real or virtual tapes. </span>
|
|
|
> * <span style="font-size: large;">Data <strong>de-duplication</strong>, across files, and backup generations. If the backup repository already contains a particular chunk of data, it will be re-used, even if it was in another file in an older backup generation. This way, you don’t need to worry about moving around large files, or modifying them. (However, the current implementation has some limitations: see </span><a href="https://obnam.org/faq/dedup/"><span style="font-size: large;">dedup</span></a><span style="font-size: large;">). </span>
|
|
|
> * <span style="font-size: large;"><strong>Encrypted</strong> backups, using GnuPG. </span>
|
|
|
</p>
|
|
|
|
|
|
<p><span style="font-size: large;">吸引我的主要是snapshot / dedup 這兩個</span>
|
|
|
<div id="extendedEntryBreak" contenteditable="false"></div>
|
|
|
<span style="font-size: large;">CentOS 6.8 裝了epel-release 之後，就可以看到這個套件，所以安裝是很簡單的</span>
|
|
|
> <span style="font-size: large;">[root@syslog ~]# cat yum.txt |grep obnam
|
|
|
>
|
|
|
> obnam.x86_64 1.8-1.el6 epel
|
|
|
>
|
|
|
> [root@syslog ~]#
|
|
|

|
|
|

|
|
|
<span style="font-size: large;">接下來，就來測試看看實際執行的狀況</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">他的指令參數有點多，可以參考官方文件</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;"><a href="http://code.liw.fi/obnam/manual/manual.html">http://code.liw.fi/obnam/manual/manual.html</a></span></p>
|
|
|
|
|
|
<p> </p>
|
|
|
|
|
|
<p><span style="font-size: large;">首先，在家目錄底下新增一個檔案 .obnam.conf</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">裡面先寫好備份的來源、目的、LOG檔案等等參數</span></p>
|
|
|
|
|
|
<p>[root@syslog ~]# cat .obnam.conf
|
|
|
[config]
|
|
|
repository=/zp/backup #備份目的地
|
|
|
log=/var/log/obnam.log #log檔案
|
|
|
root=/var/log,/etc #備份來源</p>
|
|
|
|
|
|
<p>deduplicate=fatalist</p>
|
|
|
|
|
|
<p>kee=30d
|
|
|
[root@syslog ~]#</p>
|
|
|
|
|
|
<p> </p>
|
|
|
|
|
|
<p><span style="font-size: large;">接著就只要執行 obnam backup 就可以了</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">還原的方式，是先到備份目的目錄，執行 obnam ls 找到你要的檔案之後</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">執行</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">obnam restore –to=/tmp/my_files /backup_files</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">比如說 我備份了root 目錄，然後我現在要叫回其中一個叫做 abc123的檔案到 /tmp底下</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">那指令就會是這樣</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">cd /zp/backup #切換到obnam的備份目錄</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">obnam ls |grep abc123 #確認一下有沒有這個檔案</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">obnam restore –to=/tmp/ /root/abc123</span></p>
|
|
|
|
|
|
<p><span style="font-size: large;">這樣就可以了</span></p>
|
|
|
|
|
|
<p> </p>
|
|
|
|
|
|
<p><span style="font-size: large;">至於dedup 和 keep 的用法，還要測試驗證一下，尤其是 dedup ，有點難驗證啊…</span></p>
