Move data/images from SSD to shared folder? - Nextcloud VM

I found a how-to here:

But VM is not supported, but there is another solution:

  • The official Nextcloud VM has the data already located on a separate ZFS partition, which you can easily raise in size or even add a new drive to the ZFS pool. Thanks for the hint @jeremy_fritzen.

But my issue is that this partition also is located on my small SSD (my VM’s are on my SSD).
The “even add a new drive to the zfs pool” does make me hopeful, but not sure this is what I’m looking for either…

The lonely wolf continues his search.

edit: I shutdown the vm and copied it to my hdd. Starting it now. Seems to work fine, but not sure if this is the right way to do it. Maybe it running on my SSD would be better and saving stuff to HDD as I was thinking to do it. But it looks like everything is working.
Since this would be my photos/videos from iphone I was thinking to have it easily accessible in Windows so I could upload it to a second backup location, maybe Onedrive… Not that easy the way it is now I assume. But there is still external storage that can be used I guess…
