In earlier versions of FreeNAS, there was the option to select a specific periodic snapshot task for the shadow copies export. So we could basically create multiple periodic snapshot tasks (daily/10y, hourly/2weeks) and export only the smaller one to the CIFS share as a shadow copy.
Now in 11.3, the option to select a periodic snapshot in the CIFS share seems to be gone. Where in 11.2 there was still a drop-down menu in which we could select the periodic snapshot to be exported as a shadow volume, now there is only a checkbox:
[x] Enable Shadow Copies.
This has multiple very unfortunate consequences, the first and probably worst is that in a scenario like mentioned above, the sheer amount of shadow volume copies that will be exported can cause a serious strain on the NAS when they are called from a Windows client using the "Previous Versions" functionality.
Secondly, sometimes there are older snapshots of a share that we explicitly do not want to share over CIFS.
Is there any way to select a specific snapshot to be exported - or deny another one from being exported - that I am missing here?
