<div class="bbWrapper">I didn't see this issue in the forums since 1 Feb or in the changelog known issues. Is this a new intended design or did I mess something up?<br />
<br />
<b>Issue</b><br />
In 12.0-U8.1 I could see shadow copies for items inside nested datasets. This is not the case in 13.0-U1. Now "Previous Versions" only show for items accessed through SMB shares directly linked to the dataset.<br />
<br />
<br />
<b>Configuration & Test</b><br />
Tested below with two VMs. One with 12.0-U8.1 and the other a clone of the first and upgraded to 13.0-U1.<br />
<br />
I have a media dataset nested under a shared dataset.<br />

Two VMs running side by side. On the left the 12.0-U8.1 and the 13.0-U1 on the right. Snapshots are a mix of empty and non-empty. There are four "Previous Versions" windows, two for each VM. From left to right, #1 and #3 were accessed through the "shared" share while #2 and #4 were accessed through the "shared_media" share.<br />

<div class="bbWrapper">I'd have to see a debug of your server. File a ticket in jira and I'll take a look at it when it's assigned to me. This possibly a side-effect of symlink safety checks / VFS changes in Samba 4.15.</div>

</blockquote>This is one of the things I really love about TrueNAS - developers rapidly engaging with the users to fix issues <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":smile:" title="Smile :smile:" loading="lazy" data-shortname=":smile:" /></div>
<div class="bbWrapper">PM with WIP fix sent. Do note that I mostly tested to make sure that the build completed and produced a functional update file. I was able to connect to the samba share and things look right. So you'll be doing some alpha testing of this fix if you feel like checking it. We can continue conversation via private message.</div>
<div class="bbWrapper">Shadow Copies not visible with 13u3 neither !<br />
<br />
We updated from 12u8.1 last week. No Shadow Copies (except 2 shares. Odd!)</div>
<div class="bbWrapper">Take a look at 13.0-U3.1 <span style="font-size: 16px"><span style="color: rgb(20, 20, 20)">maybe that has something to do with your problem?</span></span></div>
<div class="bbWrapper">We will look into this update for sure.<br />
Odd that we experienced Shadow Copie issues from 11 to 12, then from 12 to 13 ! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=":wink:" title="Wink :wink:" loading="lazy" data-shortname=":wink:" /><br />
