First of all, I took the full backup of my database. After that I executed some insert queries. Then I took the differential backup of my database.
Now I have created another database and tried to restore the differential backup that has taken before. But I got the following error message.
Restore failed for Server 'A'. (Microsoft.SqlServer.SmoExtended)
The log or differential backup can not be restored because no files are ready to rollforward. (Microsoft.SqlServer.Smo)
Please help me to sort out the problem.
