Simple SQL Server backup script code

In general, we will use the database maintenance plan provided by SQL Server to define the backup.
However, sometimes the maintenance plan of some machine databases cannot be successfully backed up.
The error cause may be different. In this case, we can use a simple SQL Server backup script for backup.
SQL statement for generating a simple SQL Server backup script:
Use master
Select 'backup database' + name + 'to disk = ''' F: \ sqlserver_backup \' + name + '. Bak'' with init 'from sysdatabases
Bytes -------------------------------------------------------------------------------------------------
Backup database master to disk = 'f: \ sqlserver_backup \ master. Bak' with init
Backup database model to disk = 'f: \ sqlserver_backup \ model. Bak' with init
Backup database MSDB to disk = 'f: \ sqlserver_backup \ MSDB. Bak' with init
Backup database db_app1 to disk = 'f: \ sqlserver_backup \ db_app1.bak 'with init
Backup database db_app2 to disk = F: \ sqlserver_backup \ db_app2.bak 'with init
