SQL Server backup is a page-by-page physical copy of the database files. And, generally, the size of a backup is about the size of the database. However, there are several ways to cut the backup size substantially.
Reducing the backup size has the following benefits:
In this article, we will describe how to create a backup of a SQL Server that is installed on Linux.
You can create a SQL Server backup by running the T-SQL command BACKUP DATABASE.This command saves the backup file to a specified directory. SQL Server backups are created quickly because it requires just copying data from the database files to the backup file.
When creating a backup, you do not need to stop SQL Server or switch it to single-user mode, and the database continues to work as usual during this operation.
In order to backup MySQL Server via SqlBak you have to set a connection via TCP/IP. In other words, SqlBak communicates with a database through port 3306.
While making a database backup is not a difficult task, making one the correct way can be a little more involved. So if you’re new to the process, setting up and maintaining backups on multiple servers can initially seem intimidating.
There is no one-size-fits-all solution. Choosing a good solution depends on your individual architecture, resources and security requirements. In this article, we will discuss the main approaches to managing multiple database backups, and we’ll look at the pros and cons of each approach.
Starting from SqlBak app version 3.2.9, you can export a job to a JSON file and then import it using the SqlBak.Job.Cli.exe utility. This functionality is needed primarily for automated deployment of the SqlBak application and backup jobs creation. A simple tutorial on how to do this is described in the following blog post: How to deploy SqlBak app automatically.
The sqlbak.job.cli.exe utility is a programming interface for working with the SqlBak application. It is located in the root directory where the application is installed.
This tool can be used to register the application, manage connections to DBMS, and import jobs from JSON configurations.
When SqlBak is installed on a large number of servers, the deployment can be automated in 3 steps:
Storing backups only on a local disk is not a good practice, because you risk losing them if the disk becomes corrupted. It is recommended, therefore, that you send backups to multiple destinations to always be able to restore your databases. In this blog post, we will show how to create regular SQL Server backups and automatically send some of them to a local folder and some to the cloud (Azure Storage, for example) via SqlBak.
The BACKUP DATABASE command syntax allows performing backups by specifying a drive, a network folder or Azure storage as the destination. Although it is not possible to set an Amazon S3 bucket as a backup save point, you can transfer the file to S3 using a batch script or a third-party utility.
One of the primary responsibilities of the DBA is to create regular backups. However, maintenance of the database is not limited to this.
The mechanisms that enable a relational database to run fast are based on a complex storage system that degrades over time. It leads to a general database slowdown.
