Batch file for archiving files with different names?

Question

cmd/bat

Please tell me an example of a batch file code that will archive in 7z appeared in the "F:\Microsoft SQL Base Backup\" directory - a file with a type name: KA_backup_**********_ ********* **** bak
The file in the directory appears daily.
Moreover, if there is already an archive in 7z, then do not archive it. You can see an example of the files on the screenshot.

Answer 1

On this resource, no one will write and search for you. In order to help, you need to lay out what you have already done and point to a specific place where something does not work out.

Answer 2

Base MS SQL in 7z - WHY??? MS SQL has its own system of backup and recovery, it is necessary to use it. On setting up - search for help, but there is nothing complicated, it is configured in a couple of minutes.
If you make backup copies of MS SQL databases, then you must first stop it, make a backup copy, then start it, but why make downtime in the operation of databases?
