How good are your linux skills? You can probably write a script to unshare something in the SAMBA server on a NAS and then re-share it all via CRON.
He! They are rusty. And for rusty I mean they are still called Unix skills
If shove came to push I suppose I could do that, or even directly use an old PC as backup NAS and program my way out of that. The entity of the problem is not so big for me as to spend so much time in it. I was hoping that some NAS had that feature incorporated, or easily programmable. Thanks anyway
