<article>
|
|
|
<p>很久以前就有看到這個用來備份postgresql 的 pgbarman</p>
|
|
|
|
|
|
<p><a href="https://www.pgbarman.org/">https://www.pgbarman.org/</a></p>
|
|
|
|
|
|
<p>前幾天老闆在slack 上面又提到，所以這次就花了點時間來玩玩看</p>
|
|
|
|
|
|
<p>不過呢，雖然有弄起來，但是還真不知道有些問題是怎麼解決的…</p>
|
|
|
|
|
|
<p>pgbarman 的備份有分兩種</p>
|
|
|
|
|
|
<p>streaming && rsync/SSH</p>
|
|
|
|
|
|
<p>原理就不說了，我一直沒搞懂 postgresql 的 streaming ..</p>
|
|
|
|
|
|
<p>依照官方網站上的說法，比較推薦 streaming 備份的方式</p>
|
|
|
|
|
|
<p>原因是，設定相對簡單，WTF !</p>
|
|
|
|
|
|
<pre><code>On a general basis, starting from Barman 2.0, backup over streaming replication is the recommended setup for PostgreSQL 9.4 or higher
|
|
|
The reason why we recommend streaming backup is that, based on our experience, it is easier to setup than the traditional one
|
|
|
</code></pre>
|
|
|
|
|
|
<p>事實上呢，設定的確是很簡單，可是有個致命的缺點</p>
|
|
|
|
|
|
<pre><code>Because Barman transparently makes use of pg_basebackup, features such as incremental backup, parallel backup, deduplication, and network compression are currently not available. In this case, bandwidth limitation has some restrictions - compared to the traditional method via rsync.
|
|
|
</code></pre>
|
|
|
|
|
|
<p>如果要做差異/增量備份， streaming backup 不能做</p>
|
|
|
|
|
|
<p>所以每次備份都是完整備份，也因此，barman server 需要準備很大的硬碟空間</p>
|
|
|
|
|
|
<p>以我測試的資料庫來說，一次備份，目前是133G ，如果一天四次，保留七天</p>
|
|
|
|
|
|
<p>就需要 133 x 4 x 7 = 3724G</p>
|
|
|
|
|
|
<p>咦，這樣看起來，其實也還好啦 XDD</p>
|
|
|
|
|
|
<hr />
|
|
|
|
|
|
<p>現在開始設定的部份</p>
|
|
|
|
|
|
<h4 id="設定-postgresql-server">設定 postgresql server</h4>
|
|
|
|
|
|
<p>IP: 192.168.11.19
|
|
|
hostname: hqs019</p>
|
|
|
|
|
|
<h5 id="在postgresql-建立相關帳號">在postgresql 建立相關帳號</h5>
|
|
|
|
|
|
<p>streaming backup 需要先在postgresql Server 上建立一個具有 superuser 權限的帳號</p>
|
|
|
|
|
|
<p>以及一個用來做replication 的資料庫帳號</p>
|
|
|
|
|
|
<p>這裡就簡單帶過</p>
|
|
|
|
|
|
<pre><code>sudo su - postgres
|
|
|
psql
|
|
|
|
|
|
create user barman with login superuser login password 'barmanpassword';
|
|
|
CREATE ROLE stream_barman WITH REPLICATION PASSWORD 'password' LOGIN;
|
|
|
</code></pre>
|
|
|
|
|
|
<h5 id="鄉改-pg-hba-conf">鄉改 pg_hba.conf</h5>
|
|
|
|
|
|
<p>然後修改 pg_hba.conf，加入底下兩行</p>
|
|
|
|
|
|
<pre><code># for barman test
|
|
|
host database_name barman 192.168.11.192/32 md5
|
|
|
host replication stream_barman 192.168.11.192/32 md5
|
|
|
</code></pre>
|
|
|
|
|
|
<p>當然，如果不考慮安全性問題， md5 直接改成用 trust ，可以省去一些麻煩。</p>
|
|
|
|
|
|
<h5 id="修改-postgresql-conf">修改 postgresql.conf</h5>
|
|
|
|
|
|
<p>接著修改postgresql.conf</p>
|
|
|
|
|
|
<pre><code>### for barman test
|
|
|
max_wal_senders = 5
|
|
|
max_replication_slots = 3
|
|
|
wal_level = 'archive'
|
|
|
archive_mode = on
|
|
|
</code></pre>
|
|
|
|
|
|
<p>重起 postgresql service</p>

<p>barman 在18.04 中，已經被放到標準repository 中</p>
|
|
|
|
|
|
<p>所以只要直接</p>
|
|
|
|
|
|
<pre><code>sudo apt install barman
|
|
|
</code></pre>
|
|
|
|
|
|
<p>就可以了</p>
|
|
|
|
|
|
<h5 id="設定-barman-conf">設定 barman.conf</h5>
|
|
|
|
|
|
<p>安裝完成後，在/etc/barman.d/ 底下會有兩個範例檔案</p>
|
|
|
|
|
|
<pre><code>streaming-server.conf-template
|
|
|
ssh-server.conf-template
|
|
|
</code></pre>
|
|
|
|
|
|
<p>複製 streaming-server 檔案</p>
|
|

<pre><code>sudo cp /etc/barman.d/streaming-server.conf-template /etc/barman.d/hqs019.conf

<p>restore 的部份，暫時沒有測試，我想應該是要找時間測試看看怎麼還原才對</p>
|
|
|
|
|
|
<p>不過呢，前面有提到，用streaming backup ，每一次備份都是完整備份，非常的佔用空間、時間、頻寬</p>
|
|
|
|
|
|
<p>所以還是要來試試看用rsync/SSH 備份的機制</p>
