    • WHAT IS SQL SERVER DATABASE BACKUP It is a copy of your SQL server data and transaction log placed in backup devices. You can say that it is like a second life of your crucial data after a SQL server database failure. Backup helps in recovery of data if any uncertain corruption strikes to the SQL server database.
    • DO YOU NEED TO TAKE SQL SERVER DATABASE BACKUP? The simple answer is YES! unless you don't mind to loss your data. If your database is very important for you then It is very important to make a proper backup of your valuable SQL database and update it on regular time interval. Some people say that they don't need to take backup of their database because they have redundant copy of their database. But think what happen when redundant copy of database is corrupt also.
    • TYPES OF SQL DATABASE BACKUP If you are agree with me then you will think what types of SQL database backup you should need. Don't worry! I will guide you thoroughly. SQL server provides three options to take database backup: Full, Differential, & Transaction Log Backup. Full Backup: It contains all the data of your specified database at point-in-time. You can say that it is a combination of transaction log & differential backup. Full backup takes longer time to restore in comparison of differential backup. Differential Backup: It backs database changes since last full backup. This backup is faster and require less space to store because it back-ups the changes only. Transaction log Backup: It backs all the database changes since last transaction log backup. If you use simple recovery mode for your database then you can't perform transaction log backup.
    • HOW TO TAKE BACKUP? Execute below statement to create Full database backup: USE Database-Name; GO BACKUP DATABASE Database-Name TO backup_device [ ,...n ] [ WITH with_options [ ,...o ] ] ; Execute below statement to create Differential database backup: BACKUP DATABASE database_name TO <backup_device> WITH DIFFERENTIAL Execute below statement to create Transaction Log backup: BACKUP LOG database_name To database-name-log; GO
    • DO YOU NEED TO TEST YOUR BACKUP? YES, you need to test your SQL database backup after making it. It is very important to test your backup that ensures you have accomplished backup successfully and there is no any problem with backup. You can do this by running following command on your database. RESTORE VERIFYONLY FROM DISK=N'D:TestDB.bak’
    • HOW TO RESTORE BACKUP? If you have successfully accomplished backup of your database and verified that there is no any corruption in the backup file then you can restore it. Run below command to restore an entire database from a Full database backup RESTORE DATABASE { database_name | @database_name_var } [ FROM <backup_device> [ ,...n ] ] [ WITH {[ RECOVERY | NORECOVERY | STANDBY ]}] Run below command to restore a transaction log backup RESTORE LOG { database_name | @database_name_var } [ <file_or_filegroup_or_pages> [ ,...n ] ] [ FROM <backup_device> [ ,...n ] ] [ WITH {[ RECOVERY | NORECOVERY | STANDBY = {standby_file_name | @standby_file_name_var}]
    • WHAT TO DO IF DATABASE BACKUP FILE IS CORRUPT? Sometimes when you try to restore a database backup, you may get strange error message that prevent you to restore your database. Msg 3243, Level 16, State 1, Line 1 The media family on device 'E: YourDatabaseName.bak' was created using Microsoft Tape Format Msg 3013, Level 16, State 1, Line 1 RESTORE DATABASE is terminating abnormally. Above error message indicates that database backup file is corrupt and you can't restore it.
