How to restore PostgreSQL database from backup

The first step in restoring a PostgreSQL database from backup is to restore the database files from storage to a temporary directory. These files will then be imported into the PostgreSQL database environment.

To restore files backed up using a file-level backup plan follow this guide. If your database was backed up using an image-level backup, use granular recovery to restore it as described in this article.

Xopero recommends restoring the database files to their original directory to avoid potential permission issues in a different location.

Once the database files are restored, the next step is to import them into the PostgreSQL environment.

1

Log in to your database server using SSH.

2

Enter the following command:

psql dbname < dumpfile.sql

This command does not create the database. If you want to import the database dump file into a non-existing database, you must create the database first. If you want to restore the dump file to an existing database, you must drop the database, create it again, and then import the dump file.
