<p>前面測試了用pgbarman / pgbackrest 來備份 postgresql</p>
<p>最近在準備升級client 的作業系統，從 ubuntu 14.04 準備升級到 18.04 或明年的 20.04</p>
<p>這次改從system file level 來下手</p>
<p>因為公司政策的關係，所以現在要連接internet ，需要申請</p>
<p>採用zfs 的快照來備份、還原postgresql 資料庫</p>
<p>然後 user 再去系統的proxy 設定新增一個 PAC 檔</p>

<p>但是這個動作其實是去叫NetworkManager 這個服務</p>
<p>可是在18.04 上，我會把這個服務關掉，因為他會干擾我的DNS設定</p>
<p>所以想試試看有沒有辦法不使用 NetworkManager 服務</p>
<p>又能夠在 user level 修改 proxy 參數</p>
<p>就想到了用 dconf 來做</p>

<p>很久以前就有看到這個用來備份postgresql 的 pgbarman</p>
<p>最近都在弄postgresql</p>
<p><a href="https://www.pgbarman.org/">https://www.pgbarman.org/</a></p>
<p>備份、還原測試得差不多了，就等著看到時候要用什麼方式</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>前幾天看到 pg_auto_failover 這個postgresql 的extension</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&hellip;</p>

<p>感覺挺不錯的，看起來設定很簡單，雖然之前已經測試了 keepalived 做 HA</p>
<p>不過，反正當作練功嘛，多測試一套也不錯！</p>

<p>因為老闆說要試試看用GPU 來跑postgresql 威力</p>
<p>前幾天在淘寶上買了個 SSK 的USB 3.1 Gen2 (type-c) NVME SSD 外接盒
手邊也剛好有一條多的intel 600p nvme ssd 就順手來做個比較
目標是看看有沒有可能直接用外接的SSD來跑postgresql</p>
<p>手邊剛好有一張 geforce gt 720</p>
<p>一開始沒想太多，看到有這張卡的驅動程式，然後CUDA也有支援</p>
<p>就直接從桌機拔下來，接去LAB Server ，然後就開始一連串的難關了&hellip;</p>
