Bdataset

Csnapshot

Dclone

Epool

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.

Haha, who needs a file system when you can just take a snapshot and call it a day? C) snapshot all the way, folks!

I was gonna go with B) dataset, but I think Ashlyn's got the right idea. Snapshots are the way to go here. Gotta love those space-saving tricks!

Definitely C) snapshot. I've used those before, and they're super handy for quickly preserving the state of a file system. Beats having to make a full copy every time!

I agree, snapshots are a lifesaver when it comes to preserving file system states.

I'm pretty sure the correct answer is C) snapshot. That sounds like the best description of a read-only copy that doesn't take up extra space.

I think you're right, a snapshot makes sense for that description.
