Instructor: So I just want to create some files

on this account, and I've given myself

Storage File Data Privileged Contributor

as well as SMB Share Contributor access.

And you go to the overview screen, say add directory,

and you can add a directory from here.

When I go to the browse section, I can see

that I've been able to create directories,

and obviously, I can upload files from here.

So I have chosen 16 sample files

from my local machine to upload.

Now, the purpose of this video

is really to show you about the concept of snapshots.

Now, snapshots are point-in-time, read-only versions

of your Azure file share.

This allows you to recover deleted or modified files.

And it's not a separate storage account,

it's actually gonna be your same storage account

that's going to store the snapshots as well.

So the snapshot is created manually,

or you can script it

so that you can run it at your own schedule.

These are stored as incremental backups,

so only when there's changes to those files,

then the snapshot gets updated.

The data can be retained for as long as you need.

And again, this is not a separate storage account;

it's all contained within the same snapshot here.

And once you have a snapshot,

then what you can do is restore

from a specific point in time.

So you can browse the snapshot contents,

copy files back to the active file share.

And there is such a thing

as a previous versions tab supported in operating systems

such as Windows.

So again, this is only for general-purpose v2 accounts

or for premium file shares.

So let's create a snapshot.

I'm in the snapshots operation under the file share,

and I'm gonna say add snapshot.

And I'm gonna say this is going to be previousversions.

And so now that we've created a snapshot,

we can actually go into the snapshot.

We can see the storage account file share

as it existed at the time the snapshot was created.

And if I wanted to restore this version of this file,

I can click this restore and it becomes the recent version.

So if this file has changed, has been deleted,

it's been updated since then,

I just navigate into the snapshot and I can then restore it

or download the specific version.

Now, I should point out that another way to get snapshots

is through backups.

So we'll see under operations it says backup.

Now, Azure Backup backs up its data

to a Recovery Services vault,

and I can even navigate into the Recovery Services vault.

Go under backup.

I can see backup items, Azure Storage,

Azure Files, one item.

But it's not a regular backup.

It's actually backing up as a snapshot.

So you'll see it even says Snapshot

within the Recovery Services vault.

If I go into the file share under Snapshots,

I can see the snapshot that I created manually,

as well as one that automatically kicked off

to do AzureBackup.

Now, the advantage of the automated backup

is that there's a policy,

and so the policy can say

that every day at 7:30 UTC in this example,

it's going to make a backup of anything

that's changed in the file share,

and it's gonna retain those backups for 30 days.

So I have a backup policy to automatically create snapshots

so that I can do the point-in-time recovery,

not only the ones when I can manually create a snapshot,

but I can also have it scheduled through backup.

So definitely a convenient way to keep copies

of your file share over time.
