How to set up a database backup?

Question

SQL Server

What settings I have are not correct in the backup settings. I’m making a maintenance plan, specifying which bases to backup, for example, from No. 100 to 150, the base should be backed up, which is interesting, the backup appears in the folder from No. 100 to 120, the base number, and everything beyond 120 is not backed up. If you do a manual backup, then the tabular part does not indicate where to backup, I point to the network location \\192.168.1.20\f, then everything works.

Answer 1

"manual" - executes SQL Server, "maintenance plan" - executes SQL Arent using a different account.
