Hi @Muhammad Danial Nu'man Noorman,
Thank you for your reaching out and welcome to Microsoft Q&A!
Agree with Erland's answer, I would like to introduce the solution from Ola Hallrngren for database maintenance work. Using Ola Hallrngren' script's is a good method that many professionals use.
If you don't want to use it, you can try to create a new backup maintenance plan, use exactly the same steps and parameters as before.
In addition, you might find more details about what fails by executing the maintenance plan in the command line with the dtexec utility. You'll find the command parameters to use in the SQL Server Agent Job that runs the maintenance plan. In the properties of the job, edit the step that runs the maintenance plan.
Feel free to share your issues here if you have any concerns!
Best regards,
Lucy Chen
