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.
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.
Fig. 1 System Databases
There are five system databases, these databases are created while installing SQL Server.

PALO ALTO, Calif., June 9, 2020 – ScaleGrid, a leading Database-as-a-Service (DBaaS) provider, has just announced support for their MySQL, PostgreSQL and Redis™ solutions on DigitalOcean. This launch is in addition to their current DigitalOcean offering for MongoDB® database, the only DBaaS to support this database on DigitalOcean.
MySQL and PostgreSQL are the top two open source relational databases in the world, and Redis is the top key-value database. These databases are a natural fit for the developer market that has gravitated towards DigitalOcean since its launch just nine years ago in 2011. The open source model is not only popular with the developer market, but also enterprise companies looking to modernize their infrastructure and reduce spend. DigitalOcean instance costs are also over 28% less expensive than AWS, and over 26% less than Azure, providing significant savings for companies who are struggling in this global climate.
ScaleGrid’s MySQL, PostgreSQL and Redis™ solutions on DigitalOcean are competitively priced starting at just $15/GB, the same as DigitalOcean’s Managed Database solution, but offer on average 30% more storage for the same price. Additionally, ScaleGrid offers several competitive advantages such as full superuser access, custom master-slave configurations, and advanced slow query analysis and monitoring capabilities through their sophisticated platform.

In a production environment, no matter how large or small your PostgreSQL database may be, regular back is an essential aspect of database management. In this article, you will learn how to backup and restore a PostgreSQL database.
We assume that you already have a working installation of the PostgreSQL database system. If not, read our following articles to install PostgreSQL on your Linux distribution.
Let’s get started…
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.
