Guide to Setting Up Permissions for Database Backup and Restore
In order to create database backups through SqlBak or SQLBackupAndFTP, the user specified when adding the connection must have sufficient privileges to perform the backup operation. Although you can use a superuser to create a backup without any problems, it is considered best practice to create a separate user specifically for this purpose.
Below are examples of SQL scripts for creating a backup user, as well as the necessary privileges for database recovery.
Please note that it is not necessary to grant recovery permissions immediately. This can be done when you need to restore the database.
Complete guide to SQL Server backup and restore using the command line
Creating backups of a SQL Server database is one of the most critical aspects of maintaining a system. There are various tools available for creating backups, such as SQL Server Management Studio, SqlBak, and SQLBackupAndFTP. However, performing backups via the command line interface can provide even more flexibility and customization options.
PowerShell and batch scripts can be used to perform SQL Server backups via the command line interface. PowerShell scripts offer advanced functionality, while batch scripts are simpler and easier to use. Command line backups provide more flexibility and customization options than GUI-based tools.
This article provides an overview of the process involved in performing SQL Server backups via the command line interface and discusses the advantages of using PowerShell and batch scripts.
SqlBak Guide: Backup Compression
If a database that should be backed up via SqlBak is not particularly large, then there is no need to set compression options in a specific way. It is recommended to use the default values.
The features below are designed to fine-tune compression for highly loaded systems and large databases.
SqlBak Guide: Backup Encryption
If you specify a password in the “Encrypt compressed files” section, then the backup files will be encrypted.
SqlBak Best Practice Guide
This guide contains recommendations for setting up a SqlBak backup job. This information has been developed and collected over years of interaction with SqlBak users. There will be no theory and formulas, only practical advice.
Note that these practices are not the only solutions. They are suitable in most cases, but can be fundamentally wrong under various circumstances.
Let’s consider the steps that are used to set up a backup job.
SqlBak Guide: SQL Server Differential and Transaction Log Backups
Differential and transaction log backups are available only for local SQL Server connections. If you backup SQL Server using SqlBak, then you can add differential or transaction log backups to your backup plan in the “Advanced backup schedule” settings.
SqlBak Guide: Which databases should be chosen in a backup job?
In one database management system, there can be multiple databases. When creating a backup job, you can choose which databases specifically need to be backed up. The backup of each database will be made independently from the other databases and placed in a separate archive.
SqlBak Guide: Backup Storage Selection
SqlBak supports sending to 16 different storage types. In one job, you can specify multiple backup storage locations, and for each storage location, you can specify the duration of backup storage on it.
Note:
SqlBak does not store your backups on its servers. Backups are sent directly from your server to the storage location.

SqlBak Guide: Optimizing Backup Job Execution Time
For large data volumes, backup job execution can take a lot of time. However, there are several tricks that can help optimize the time.
