How to Dump Database in SQL Server

What is SQL dump

SQL dump is a file that contains the SQL statements required to recreate a database or a specific set of data. It is essentially a textual representation of the database schema and/or data that can be used to restore or migrate databases across different environments. Dump Database SQL Server are typically used for backup purposes, version control, database replication, or sharing data with other systems. And there are several compelling reasons to dump database SQL server:

1. Disaster Recovery: It serves as a critical component of disaster recovery plans to dump database SQL server. By regularly dumping, you ensure that your database can be restored in the event of data loss or system failures.

2. Database Migration: When migrating, SQL dumps provide a convenient method to transfer the schema and data to the new environment.

3. Version Control: By storing periodic snapshots of the database in the form of SQL dumps, you can track changes, revert to previous versions and have a comprehensive audit trail.

What is the difference between dump and backup

Dump and backup are often used interchangeably in the context of data management, but there are subtle differences between the two concepts.

◆ Scope: Dumps are usually focused on specific database objects or subsets of data, whereas backups encompass the entire database or designated portions.

◆ Format: Dumps are often textual representations of SQL statements, while backups can be stored in various formats, including binary files or compressed archives.

◆ Purpose: Dumps are commonly used for replication, version control, or sharing data, while backups are primarily intended for disaster recovery, system migration, or ensuring data integrity.

It's important to note that the terminology and usage may vary depending on the specific database management system or industry context.

How to dump a database in SQL server

Except for SQL Server Management Studio dump database, the mysqldump command proves to be an efficient solution. Mysqldump is a command-line utility that is used to generate the logical backup of the MySQL database. It is a versatile tool that can be used to back up all databases, only data, only structure, all tables in the database, a single table, etc. The following steps outline the process:

mysqldump -u [user name] –p [password] -h [host name] [options] [database_name] [tablename] > [dumpfilename.sql]

▸ -u (or --user=[username]) represents the username required to establish a connection with a MySQL server.

▸ -p represents the password associated with the username used for server connection.

▸ -h (--host=[hostname]) specifies the name of the server to establish a connection for data dumping.

▸ options denote additional parameters that can be configured for the backup process.

▸ database_name corresponds to the name of the specific database intended for backup.

▸ tablename signifies the name of the table to be included in the backup process.

▸ < or > indicates the direction of the process, where ">" denotes the database backup, and "<" signifies database restoration.

▸ dumpfilename.sql refers to the file path where the database backup will be saved as an SQL dump file.

Note: Typically, the MySQL Server installation directory contains mysqldump. For instance, the directory's path for MySQL 8.0 is C:Program FilesMySQLMySQL Server 8.0bin. This is why we advise adding the directory to mysqldump command.

Examples of backup MySQL database using mysqldump command

✤ Back up all databases

To create a backup of all databases, execute the following command by adding the --all-databases parameter:

mysqldump --host=dbfmylast --user=root --port=3306 --p --all-databases > D:\backup_all_databases.sql

✤ Back up only data

Use the command with the -no-create-info parameter to take a backup of your data without the database structure. For instance, dump the sakila database's data.

mysqldump --host=dbfmylast --user=root --port=3306 -p --no-create-info sakila > D:\backup_data_only.sql

✤ Back up only structure

You might need to export the database or table structure without the data in some circumstances. Run the command with the -no-data parameter to accomplish that.

mysqldump --host=dbfmylast --user=root --port=3306 -p --no-data sakila > D:\backup_database_structure_only.sql

✤ Back up all tables in the database

By including the chosen table names in the command, the mysqldump command can create a backup of the database's whole collection of tables or only a subset of them. Remember that a space should be used to divide the table names. For instance, execute the following command to dump all tables:

mysqldump --host=dbfmylast --user=root --port=3306 -p sakila city country category > D:\backup_selected_tables.sql

✤ Back up a single table

Give the mysqldump command the name of the particular table if you want to take a backup of single table in the database. Take the inventory table from the Sakila database as an example.

mysqldump --host=dbfmylast --user=root --port=3306 -p sakila inventory > D:\backup_single_table.sql

Best alternative for SQL Server Management Studio

While SQL dumps serve as a reliable method to create backups of databases in SQL Server, it's important to consider comprehensive data backup solutions that provide additional features and enhanced security.

Next, the following part is about how to use AOMEI Cyber Backup to backup all of your SQL Server within simple steps.

Prerequisites to SQL Server backup

1. At first, please access to Source Device >> Add Microsoft SQL. It will automatically appear if the database is present and the version is compatible. Otherwise, you need download proxy program to local and click Already installed proxy and select the unadded proxies.

2. Click ... >> Authentication to validate the database instance. You can choose Windows Authentication or SQL Authentication. Enter the credentials and click Verify.

Then you can go to schedule and specify your SQL database backup.

Steps to backup SQL Database via AOMEI Cyber Backup

Click Backup Task on the left menu bar, then click Create New Task to start create database backup task. Please follow the simple steps to back up your SQL databases.

1. Choose backup type as Microsoft SQL Backup, and you could also try VMware Backup or Hyper-V Backup.

• Task Name: Set a name for your SQL backup task to make it easy to find.

• Device Name: Select the databases you want to backup.

• Target: Select a location as the destination path. You can choose a local or network path as a storage end.

2. Click Schedule Backup to run your SQL database backups automatically and regularly. And you can also specify the backup methods and time.

3. Backup Cleanup (optional): If you set up Backup Cleanup, it can automatically remove history backup versions based on rule to save storage space.

4. Email Notification (optional): If you set up Email Notification, you can receive email notifications when the task is abnormal or successful.

5. Finally, click Start Backup to create the backup task and perform backup.

Conclusion

In conclusion, this article has provided a comprehensive understanding of dumping databases in SQL Server, and has also explored the step-by-step process of backing up a MySQL database using the mysqldump command.
