maximum account and prefix
The structure and configuration of your storage and backup plans are entirely up to you and depend on your goals and requirements. As long as you can access your backups and restore data successfully, there's nothing wrong with your configuration. Regarding the prefix, it serves as a unique identifier that links backup data to a specific computer. For instance, if you replace your computer, restore all the data from the old one, and wish to continue backing up to the same storage, the prefix will assist you in configuring that transition seamlessly.
