How To Backup PostgreSQL Database

You might be able to afford this kind of data loss once in a while, but now imagine it's an entire database with Terrabytes of information—not just one document. Especially if that information is in a production environment, the damage could be catastrophic, costing millions of dollars. Not even mature organizations can afford these mistakes, and database backups prevent precisely this kind of situation.

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
Master
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
Model
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
MSDB
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
TempDB
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
Resource
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

Backup a Single PostgreSQL Database

PostgreSQL provides the pg_dump utility to help you back up databases. It generates a database file with SQL commands in a format that can be easily restored in the future.

To back up, a PostgreSQL database, start by logging into your database server, then switch to the Postgres user account, and run pg_dump as follows (replace tecmintdb with the name of the database you want to backup). By default, the output format is a plain-text SQL script file.
