After a while can't sync from mounted hdd help need pls.

[Chris]

Hi!
This is my first post here and I need a bit help about how to solve my problem.

Here is my problem:
OS: Lubuntu 18.04
Have to sync files&folders from win7 shared forledrs and I use smb to have access to win7...
I also use When scheduler to run the batch...

Everithyng works like a charm until I left the pc alone for a while.
Lets say I dont touch anything for 10min.
After that I got an error during the sync does the target folder, which is actually my folder on my win7 pc is unreachable.

I have to say, during the time where the Linux pc is untouched I'm working on the win7 pc, so to say that pc cant go into sleep etc. mode.

When I mount again the hdd from the win7 pc to the Linux pc the next triggered sync is working again for some time.

I think does my Linux dismount the win7 and maybe that cos the problem.

Any idea pls?
How can I auto mount the desired location on my LAN on boot time on Linux?
How can I make some alarm so to say and trigger the mount function again if for some reason the win7 was disconnected?

Thank you for any help or suggestion.
My best regards.
