What is an SQL database?

Databases are at the heart of many applications and IT systems. They make it possible to store, organize and retrieve data efficiently. Among the most common types of databases are SQL (Structured Query Language) relational databases.

Backing up SQL databases is a very important part of data management for many businesses. Data loss can have serious consequences, such as a service outage or considerable financial losses.

How do you create dumps (database copies)?

Creating a dump means making a copy of data, usually from a database or file system, in order to back it up or migrate it. Here are the general steps for creating a dump, whatever tool or technology you use:

  • Choosing the tool: Select the appropriate tool or method for the dump based on what you want to back up. Common tools include mysqldump for MySQL databases, pg_dump for PostgreSQL databases, or SQL Server Management Studio for SQL Server databases.
  • Preparation: Make sure the tool is properly installed. Also make sure you have the access rights needed to perform the dump.
  • Dump command: Use the appropriate command or syntax for the tool you have chosen.

Here are some examples:

  • For MySQL with mysqldump:

mysqldump -u [user] -p [database_name] > [backup_file_name].sql

  • For PostgreSQL with pg_dump:

pg_dump -U [user] -W [password] -f [backup_file_name].sql [database_name]

 

  • For SQL Server with SQL Server Management Studio, you can use the graphical interface to generate a backup (dump) of the database.

Note that the exact method may vary depending on the tool you use and the database or file system involved. Be sure to consult the relevant documentation for instructions specific to your case.

Backing up with KiwiBackup

The files produced by these commands must then be stored in a specific folder so they can be backed up with KiwiBackup.

Ideally, the dump should be created before the KiwiBackup backup runs. To do this, you can set up a scheduled task or a cron job that starts generating the dumps about an hour before the time scheduled for the KiwiBackup backup.

For example, if generating a full dump of your database takes about an hour, you could run the backup script at 9:00 p.m., then trigger the KiwiBackup backup at 10:15 or 10:30 p.m. This ensures there is enough time for the dumps to be fully generated before the KiwiBackup backup takes place.
