This recipe will discuss the differences between local and remote filesystems, as well as the core differences between Btrfs and ZFS.

The backbone of an operating system (OS) is the local filesystem. It enables efficient storage and management of files and directories on a computer or server using a hierarchical structure. This structure allows users and programs to easily create, modify, and access files on local storage devices such as hard disks, solid-state drives, and storage logical unit numbers (LUNs) from a local storage area network (SAN) or cloud provider.
