Summary: In this article, we will show the right way to backup and restore SQL Server Database. The ways to backup and restore a database applies to SQL Server 2019, 2017, SQL Server 2016, SQL Server 2014, and SQL Server 2012. We will cover SQL Server on-premises and focus on SQL Server for Windows. SQL Server for Linux is a little different and will not be covered here. You cannot restore a database from a corrupted or obsolete backup. In that case, you can try repairing the corrupt SQL database using Stellar Repair for MS SQL software.
Here are few important points related to backup and restore SQL Server Database:
A good practice to back up a database is to do it automatically. We will usually automate the backup using the SQL Server Agent.
The SQL Server Agent is available in most of the SQL Server editions (Enterprise, Standard, etc. ) except in the Express edition:
The best time to backup is at night when there are not many users online. Backup consumes a lot of resources and it might be slower the performance when people is using it.
Once the backup is complete, restore your database with another name to verify that the backup is working fine. This practice will help you restore the database from the backup without any issue.
It is possible to automate the backup and restoration using the SQL Server Agent. You can use one step to backup and on success, you can try a restoration. Use another name of the database to restore in order to avoid problems with the database online. In general, use another machine to test the restoration if possible.
Differential backups can save you a lot of space instead of many full backups. Especially, if not many changes were done in the database.
Also, you can backup per files or filegroups instead of full backups.
Do not ever store your backups in the same hard drive or server than the data files of your current database. Always keep the backups in another server and if possible, make sure that the other server is in another city, office or country. You never know if a natural disaster will occur. If possible try to store the backups in a safe place.
If possible, use the compress option to compress your backup. Not all the SQL Server editions support this feature, but if it supports, use it. It will save a lot of space:
In order to have security, you can use Transparent Data Encryption to secure your backups and store your data. This feature will avoid someone to get your data from your database.
If the database is corrupted and you cannot back up it, you can always use Stellar Repair for MS SQL. This software allows repairing corrupt databases. Once repaired, you can successfully create a backup.
