Show Suggested Answer

Suggested Answer: C

A snapshot is a read-only point-in-time copy of a file system. The copy-on-write design

of ZFS makes them essentially ''free'' - They are space efficient and instantaneous, providing an invaluable part of backup strategies and synchronizing data between systems.

Incorrect:

Not A: A ZFS vdev (aka 'virtual device') is either:

a single disk, or

two or more disks that are mirrored, or

a group of disks that are organized using RAID-Z.

There are also special kinds of vdevs like hot-spares, ZIL or cache devices, etc.

Not D:

Clones are writeable snapshots, ideal for storing many private

copies of shared data for operations such as data migration, test

and development, or backup.

Snapshots are perfect for testing too, they make it so easy to revert back to a previous state.
