What is ZFS?
If you don’t know, it’s a great time to learn. ZFS [1] was developed at Sun Microsystems in the early 2000s. ZFS is not just an on-disk data storage format like FAT or NTFS, but a complete storage software stack from stern to stem. Its purpose is applying the CIA triad to data. It is an alternative to RAID (both hardware and software).
