World backup systems

[Minerpro205]

What problem does this feature solve?

The ability to make a world or multiple worlds automatically backup into a separate folder on timed intervals, likely with a limit on the backup amount that can exist at once (only "configured amount" existing at a time, older ones getting deleted for newer ones). For those moments where something majorly gets screwed up, a world gets deleted that shouldn't have been, or any other situation where you'd need a backup. This should likely be it's own separate command with it's own permission, as it would only be useful to owners/developers, unless the backups are accessible to be changed in-game.
