![]() ![]() This approach effectively saves significant resources and time that would have otherwise been consumed and required for backing up the previously backed-up old data. In cases where the old data undergoes minimal modifications, we can back up only the recently added and modified data in the database since the last backup was created. Differential backup: BACKUP DATABASEīacking up the whole database every time can be very time-consuming and unnecessary. In SQL, we use the BACKUP DATABASE command to create a full backup of the database, with which we also have to mention the name of the database that we wish to back up and the disk location where the backup needs to be created. Also, the restoration process becomes time-consuming.īut once the backup is created using a full backup strategy, at the time of necessity, the database can be restored to the state when it was being backed up. ![]() As the backup process involves backing up the entire database data, it may take some time, especially when dealing with a large amount of data. In this backup strategy, the query backs up all the database data to the specified disk or memory location. The types of backups in SQL are specified below. Many types of backup are available in SQL, and all differ in strategy, content, scope, and methodology of the backup and restore process. In this article, we will learn about the types of backups available in SQL and also study some of them in detail. Restoring the backup file using SQL backup will revert the database to its state at the time of backup creation. You must backup your database frequently to have the updated backup of your database available to you. It supports both single and multiple database backup scenarios. ![]() This utility is designed to create a logical backup consisting of SQL statements that can be executed to restore the database to its state when the backup file is created. Additionally, the database must be running. To utilize this utility, you must have access to the database and possess the select privilege assigned to its tables. For this reason, SQL provides us with a facility to back up the database using the SQL backup utility. ![]()
