更新時(shí)間：2021年02月01日 15:36:58 作者：岳麓丹楓001
這篇文章主要介紹了PostgreSQL物理備份恢復(fù)之 pg_rman的用法說明，具有很好的參考價(jià)值，希望對大家有所幫助。一起跟隨小編過來看看吧
簡介
類似oracle 的 rman, 用于 postgres的備份與恢復(fù)
下載
https://github.com/ossc-db/pg_rman/tree/V1.3.9
安裝
tar zxvf pg_rman*.tar.gz chown postgres.postgres -R pg_rman* su - postgres cd xxx/pg_rman* make && make install
使用
開啟歸檔
[postgres@node_206 /postgresql/pgsql/archive_log]$tail -3 /postgresql/pgsql/data/postgresql.conf #for pg_Rman archive_mode = on # enables archiving; off, on, or always archive_command = 'test ! -f /postgresql/pgsql/archive_log/%f && cp %p /postgresql/pgsql/archive_log/%f'
重啟 PG
pg_ctl restart -m fast
初始化
pg_rman init -B /postgresql/pgsql/pg_rman_backups
全量備份
pg_rman backup --backup-mode=full -B /postgresql/pgsql/pg_rman_backups
實(shí)例

總結(jié)
在 基于時(shí)間點(diǎn)恢復(fù)時(shí), 如果之前做過恢復(fù)，那么此時(shí)DB與之前的備份已經(jīng)不在同一時(shí)間線上?；謴?fù)默認(rèn)只沿著基礎(chǔ)備份建立時(shí)時(shí)間線恢復(fù)而不會切換到新的時(shí)間線，如果不做處理，恢復(fù)結(jié)果將和前面的完整恢復(fù)一模一樣，恢復(fù)不出新插入的數(shù)據(jù), 所以建議在恢復(fù)之后,可以接著做一個(gè)全庫的備份
恢復(fù)之后, 數(shù)據(jù)庫可能處于 read-only狀態(tài),此時(shí)可以用超戶執(zhí)行select pg_wal_replay_resume(); 或者在啟動數(shù)據(jù)庫實(shí)例前在postgresql.conf中添加recovery_target_action=‘promote'
pg_rman init 之后會生產(chǎn) pg_rman.ini文件, 此時(shí)可以編輯該文件并添加備份策略,
我們以一個(gè)例子來說明：總共保留兩周的數(shù)據(jù)，即14天的數(shù)據(jù)，每周進(jìn)行一次全備，每周一和周三的2:00做一次增量備份，每天進(jìn)行一次歸檔備份，這樣我們需要對pg_rman.init中做如下配置：
KEEP_DATA_GENERATIONS=2 KEEP_DATA_DAYS=14 KEEP_ARCLOG_DAYS=15 KEEP_SRVLOG_DAYS=180
因?yàn)槲覀冃枰獌蓚€(gè)全備份，所以KEEP_DATA_GENERATIONS=2
兩周的數(shù)據(jù)所以KEEP_DATA_DAYS=14，而可以把WAL日志多保留一天，所以KEEP_ARCLOG_DAYS=15
至少保留1000個(gè)WAL文件，每個(gè)WAL為16M，所以大約16G，占用空間不算大。
KEEP_SRVLOG_DAYS=180，通常程序日志不太，所以保留180天的日志，即3個(gè)月。
建議備份時(shí)添加參數(shù) -C -Z
建議恢復(fù)時(shí)添加參數(shù)–hard-copy
如果沒有指定這個(gè)參數(shù)，pg_rman實(shí)際上是把在歸檔目錄中建一個(gè)軟鏈接 指向恢復(fù)中要用到的WAL日志文件。如果指定了這個(gè)參數(shù)，則執(zhí)行真的拷貝。
過程中遇到的問題
Linux 系統(tǒng)時(shí)間與 PG 中的時(shí)間不一致
解決方法：
rm -f /etc/localtime ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教。
