Pg-dumpall generates a single script file with SQL commands that can be entered into psql to restore PostgreSQL databases. Only one database at a time is dumped by pg-dump, and neither roles nor tablespaces information is included. ![]() Pg-dump is a utility for backing up a PostgreSQL database even when the database is being used simultaneously and it doesn’t prevent other users from accessing the database. ![]() Generally, there are several PostgreSQL tools for database backup and recovery: pg_dump /pg_dumpall and plsql, pg_restore. How do you backup and restore the PostgreSQL database? We can migrate Oracle DB, MySQL, and SQL Server to PostgreSQL and vice versa. Long-term benefits: The initial investment in database backup may seem costly, but it produces long-term benefits, for instance, backup saves time, money, and energy trying to retrieve lost data.ĭata research: Saved data could be used to research on market and customers, generate annual audits or reports, and plan for the business's future.ĭatabase migration: Sometimes, we just need to backup and export data for migration. Additionally, as the basis and source of disaster recovery, database backup brings peace of mind facing data loss.īusiness continuity: Being the intangible core asset of a company, frequent database backup ensures data availability and therefore, business continuity. Too many reasons to list here that necessitate database backups for later data recovery.ĭata loss prevention: Having regular database backups minimizes data loss in the event of ransomware attacks, system failures, or other disasters.ĭisaster recovery: Backup is the safest, simplest, and most reliable way to restore lost data after disasters. We all know those database backups are the bottom line and safety net for data loss prevention and disaster recovery in case of any mishap, but not all of us really understand the necessity and stick to the business continuity plan based on backups. With it, you can establish the data types, customize your functions, control the metadata, and write code in a different programming language (Perl, Tcl, and Python) without having to recompile the database. ![]() Working with a number of technologies such as Multi-Version Concurrency Control, hot backups, point-in-time recovery, asynchronous replication, query planner, fault tolerance, etc., PostgreSQL differentiates it with extensibility and compliance from others. Data points are kept in rows with columns acting as various data properties. The database runs on multiple widely used operating systems like Linux, Windows, Mac OS, FreeBSD, and OpenBSD. PostgreSQL, or Postgres, is an extensible open-source relational database management system (RDBMS) that supports SQL and JSON querying. But before that, let me take you through what is PostgreSQL and find out why it is used so extensively. Also, you’ll get the hang of their uses, and another easier substitute available is provided afterwards. In this article, you’ll learn various PostgreSQL backup and restore techniques with built-in tools and why you need to do so. Database backups, which copy data from a database and store them elsewhere for data retrieval in event of cyberattacks, human errors, and accidents, are one of the methods databases keep the data safe and business in operation.
