Why we got “BACKUP LOG cannot be performed because there is no current database backup” in SQL Server?

Before performing a Transaction log Backup, you should first be aware of the following:

  • As a mandatory pre-request, you must perform a database full backup before performing a transaction log backup.
  • Log Backup is working with Full or bulk-logged recovery models. it’s not working with a simple recovery model.
  • You may need to perform a full/differential database restore when you perform a restore for the transaction log backup.

In this example, we will perform a bundle action to take a full database backup then take a transaction log backup at once.

BACKUP DATABASE [SharePoint_Config] TO DISK = N'C:\SharePoint_Config.bak'
GO
BACKUP LOG [SharePoint_Config] TO DISK = N'C:\SharePoint_Config_log.bak'
GO

Restore a database from an older SQL Server version to a new version

You may also get this error “BACKUP LOG cannot be performed because there is no current database backup” if, you are trying to perform a database restore from an older SQL Server version to a new SQL Server version.

Actually, this issue occurs if you first have created an empty database with the same name, then you have tried to restore your backup. In this case, to be able to restore the database backup to a newer version, you have two options:

  1. Delete the newly empty created database and try to restore the backup from the Device.
  2. or leave it and just make sure to do the following:
    • In “Restore Database” Dialog, in the “Options” tab.
      • Check “Overwrite the existing database (With Replace)”
      • Uncheck “Take a tail-log before restore”.
