Write a simple batch/shell-script that will copy the database file into your required location with timestamp prefixed to the file name. Schedule the batch/shell-script to be executed for the frequency you desire.
That overlooks the issue that running a backup every 1 minute would seriously hurt performance on a database. Scheduling a script to run a backup is fine, but every 1 minute would have serious consequences. This is one of those situations where there is a mismatch between the problem being solved and the proposed solution, namely that keeping a database in sync should not involve spamming backups but instead should rely on a replication pattern.
