How to create a backup of the Postgres Database in DigitalOcean?

Postgres, also known as PostgreSQL is a free and open-source relational database management system with an emphasis on flexibility and SQL conformance. It is regularly employed to store and modify data relevant to websites and applications.

It is crucial to develop a backup plan in order to guard against data loss, as with any valuable data. In this article, we will discover the steps to create a backup for the Postgres database in DigitalOcean.

Pre-requisites

Ubuntu 12.04 VPS with PostgreSQL 9.1.

Backup Process

We can use the pg_dump tool in PostgreSQL to export database data to a file for backups. Using the Linux command line, we execute the pg_dump command. The command runs as the superuser since a user who has access to view all database data can only execute it.

Remember that pg_dump also has the same authentication constraints as any other client software. This implies that we have to make sure the login information is current for the systems we’re trying to back up. The syntax of pg_dump is as follows:

pg_dump name_of_database > name_of_backup_file

We can log in as the “postgres” user and issue the following command on the default database, also known as “postgres,” for a practical illustration. From a remote system, we can execute this command as long as that system has access to the database because it is essentially a PostgreSQL client application.

sudo su - postgres pg_dump postgres > postgres_db.bak

We can pass the “-h” argument to specify the remote host and the “-p” flag to define the remote port if we want to backup a distant system:

pg_dump -h remote_host -p remote_port name_of_database > name_of_backup_file

If necessary, we can also use the “-U” option to designate a different user. The syntax is as follows:

pg_dump -U user_name -h remote_host -p remote_port name_of_database > name_of_backup_file
