SQL Server backups, in itself, is an immense topic; so tremendous. In this blog, we are going to concentrate on the types of backups that are accessible to us, and see how to pick what we need, and what perspectives we base that choice on. This comprehension would, thus, assist with choosing the backup-and-restore technique.

Know About Different Types of Backups in SQL Server and How to Create them

  1. Full Backups
  2. The most well-known kinds of SQL Server backups are full backups, also called database backups. These backups make a total backup of your database just as a major aspect of the transaction log, so the database can be recovered. This considers the least difficult type of database restoration since the entirety of the contents is contained in one backup.

    Create Full Backup

    1. Open SSMS and right-click on the database name.
    2. Click on the “Tasks” and then “Backup”.
    3. Choose “Full” in the backup types.
    4. Choose “Disk” for the destination.
    5. Click on the “Add” button and add the backup file and click “Ok”.
  3. Differential Backups
  4. A differential backup isn’t autonomous, and it must be founded on the most recent full backup of the data. That implies there ought to have a full backup as a base. A differential backup contains just the data that has changed since the differential base. Normally, differential backups are littler and quicker to make than the base of a full backup and furthermore require less disk space to store the backup.

    In this manner, using differential backups can spare accessible space and accelerate the way toward making incessant backups to diminish the danger of data loss. At restoration time, the full backup is restored first, trailed by the recent differential backup.

    Create Differential Backup

    1. Open SSMS and right-click on the database name.
    2. Click on the “Tasks” and then “Backup”.
    3. Choose “Differential” in the backup types.
    4. Choose “Disk” for the destination.
    5. Click on the “Add” button and add the backup file and click “Ok”.
  5. Partial Backups
  6. A Partial backup can be given for either a Full or Differential backup. This cannot be used for Transaction Log backups. In the event that a filegroup is changed from Read-Only to Read-Write, it will be remembered for the following Partial backup, yet on the off chance that you change a filegroup from Read-Write to Read-Only, you ought to make a filegroup backup since this filegroup won’t be remembered for the following Partial backup.

    Create Partial Backup

    A partial backup can be finished uniquely by using T-SQL. The accompanying models tell you the best way to make a partial backup.

    Create a SQL Server full partial backup

    BACKUP DATABASE TestBackup READ_WRITE_FILEGROUPS

    TO DISK = ‘C:\TestBackup_Partial.BAK’

    GO

    Create a SQL Server differential partial backup

    BACKUP DATABASE TestBackup READ_WRITE_FILEGROUPS

    TO DISK = ‘C:\TestBackup_Partial.DIF’

    WITH DIFFERENTIAL

    GO

  7. Transaction Log Backups
  8. On the off chance that your database is set “Full” or “Bulk logged” recovery model then you will have the option to issue “Transaction Log” backups. By having transaction log backups alongside full backups you can do a point in time recovery, so in the event that somebody incidentally erases all data in a database, you can recover the database forthright in time directly before the deletion happened. The main proviso to this is if your database is set to the “Bulk logged” recovery model and a bulk operation was given, you should recover the whole transaction log, so you can’t do a point in time restore using a transaction log backup that contains a bulk-logged operation.

    A transaction log backup permits you to backup the active piece of the transaction log. So, after you issue a “Full” or “Differential” back up the transaction log backup will have any transactions that were made after those different backups finished. After the transaction log backup is given, the space inside the transaction log can be reused for different procedures. On the off chance that a transaction log backup is not taken, the transaction log will keep on developing.

    Create Transaction Log Backup

    1. Open SSMS and right-click on the database name.
    2. Click on the “Tasks” and then “Backup”.
    3. Choose “Transaction Log” in the backup types.
    4. Choose “Disk” for the destination.
    5. Click on the “Add” button and add the backup file and click “Ok”.

    So, we have discussed Different Types of Backups in SQL Server and how to create backups. But if you don’t have any backup of your database and you are unable to access your database. And, also you want to recover the database. Then, no need to worry about this, you can recover your database without a backup image.

    So, in order to recover the database without backup files, the best and ideal approach is by using a third-party tool, for example, the Emaildoctor SQL Recovery tool. This tool is a widely used tool to recover the database without any backup image. Moreover, you can also recover the database if the database files got corrupted due to any reason. This software scans the database files and recovers the corrupted database easily.
