Backup with date to azure blob storage url

Question

Im trying to do backups to an azure blob storage that have the date when the backup is made, that way the job does not fail when the backup is generated with the same name, I am concatenating convert(varchar(500),GetDate(),112) + '.bak') but im getting the next error in the job execution

Incorrect syntax near '+'. [SQLSTATE 42000] (Error 102). The step failed.

The script:

Backup database model to url = 'https:containerurl/azurecontainer/model' + convert(varchar(500),GetDate(),112) + '.bak') go

Answer 1

You can't do concatenation in the backup command. But you can have a variable for the file name, so construct the file name first into the variable and use that variable in the backup command.
