恢复 Postgresql pgBarman

编程问答 2022-05-10

问题描述

我已经设置了一个 postgresql 数据库，我想备份它。

我有 1 台服务器和 Barman 的主数据库和 1 台。 所有设置都在工作，我可以用酒保备份我的数据库。

我只是不明白如何在我每天进行的备份之间的确切时间点恢复我的数据库。

barman@ubuntu:~$ barman check main-db-server
WARNING: No backup strategy set for server 'main-db-server' (using default 'exclusive_backup').
WARNING: The default backup strategy will change to 'concurrent_backup' in the future. Explicitly set 'backup_options' to silence this warning.
Server main-db-server:
        Postgresql: OK
        is_superuser: OK
        wal_level: OK
        directories: OK
        retention policy settings: OK
        backup maximum age: OK (interval provided: 1 day,latest backup age: 9 minutes,59 seconds)
        compression settings: OK
        Failed backups: OK (there are 0 Failed backups)
        minimum redundancy requirements: OK (have 6 backups,expected at least 0)
        ssh: OK (Postgresql server)
        not in recovery: OK
        systemid coherence: OK (no system Id available)
        archive_mode: OK
        archive_command: OK
        continuous archiving: OK
        archiver errors: OK

当我备份数据库时

barman@ubuntu:~$ barman backup main-db-server

        00000005000000000000001C.00000028.backup

我不知道如何在两次备份之间的时间内恢复我的数据库：/

谢谢
