A storage administrator is reviewing NAS volume space allocation and is concerned that the Snapshot copies that are recently created to protect the volumes are not storing the data from the volumes. One volume contains over 20 GB of data, although the latest SnapShot copy contains only 198 KB of data.
In this scenario, which statement is true?

Wait, only 198 KB? That’s surprising! What’s going on?

Totally agree with A! That's how ONTAP works.

A is correct! Snapshots use metadata, not data blocks.

B seems off. Snapshots usually capture all changes, right?

D doesn’t make sense. Snapshots are almost instant, not slow.

I vaguely recall something about Snapshots being created in the background, but I don't think that explains the small size. Maybe option D?

I practiced a question similar to this, and I think the key is that Snapshots only capture changes, so option B sounds plausible.

I'm not entirely sure, but I feel like the Snapshot policy could limit what gets saved, which makes me lean towards option B.

I remember that ONTAP uses metadata for Snapshot copies, so I think option A might be correct.

The Snapshot policy is probably the key here. If it's set to only capture recent changes, that would explain the small Snapshot size. I'll make sure to read that part carefully.

Hmm, I'm not sure about this one. The options all seem plausible, but I'll have to really think it through to pick the right answer.

Okay, let me think this through. ONTAP uses metadata to create Snapshot copies, so that must be the right answer here. I'm confident I can get this one.

I'm a little confused by the details here. The volume has 20 GB of data, but the Snapshot only has 198 KB? That doesn't seem right.

This question seems pretty straightforward. I think the key is understanding how ONTAP handles Snapshot copies.

Haha, so the Snapshot copies are just like those magic trick boxes - they seem empty, but there's actually a whole universe inside! Gotta love technology.

Restoring the volume from all the Snapshot copies? That's a lot of data to juggle. I hope the ONTAP wizards have a good system for that.

A) ONTAP references metadata when creating Snapshot copies instead of copying data blocks.

The background process for creating Snapshot copies? Sounds like a bunch of wizardry going on behind the scenes. I bet it's a real-time saver, though.

I don't think so, because if that were the case, the Snapshot copy should still contain more than 198 KB of data for a 20 GB volume.

But what about option B) The Snapshot policy is defined to create the Snapshot copy with only the most recent data changes? Could that be a possibility?
FL
Floyd

Hmm, I'm pretty sure the Snapshot policy is supposed to capture all the changes, not just the latest ones. This sounds like a tricky situation.

I agree with Gwenn, because if the Snapshot copy only contains 198 KB of data for a 20 GB volume, it must be referencing metadata.
GW

I think the correct answer is A) ONTAP references metadata when creating Snapshot copies instead of copying data blocks.

Wait, so ONTAP only stores metadata in the Snapshot copies? That's wild! The volume must be filled with some invisible data then.

D) The Snapshot copies are created by using a background process that takes time to build.
