SQL Server automatic backup cannot delete expired backup files

SQL Server automatic backup cannot delete expired backup files

The Database Server backs up the database at two o'clock every morning and deletes the database backup file five days ago. Otherwise, the hard disk will pop up.

Windows logs provide the following information:
SQL Server scheduled job 'db maintenance plan "Database Maintenance Plan 1" DB Backup job. '(0x2da54a5bbefc2b4a874428b91602c52a)-Status: Failed-invoked on: 01:00:00-message: Job failed. Scheduling 28 (1st scheduling) wakes up and calls the job. The last step is Step 1 (step 2 ).

Logs in SQL Server:
Sqlmaint.exe failed [SQL state 42000]

It seems a bit confusing.

It was discovered that one of the databases to be backed up was offline. As a result, the database cannot be backed up or expired, I had to re-host it.
