Hi all,

I'm looking for a data backup solution that is to be applied on 3 PCs on one physical locations, to a net-share (provided by a NAS).
The 3 PC do have Windows 10 (22H2 ++) (the NAS is right now not defined, but should be Linux based as there are other tasks foreseen for that as well, but should not be of concern here!).

The Idea should be:
  • that on the Windows Clients, there is a Program/Script that is configured and can run time triggered and manually on demand.
  • the script should "synchronize" the defined folders (no need for an image based backup!!!) to the remote configured net share.
  • On the net share the Windows Clients Backup user (the user that is used to perform the login on the NAS for backup) do only have write access, but no delete/overwrite.


The "synchronize" should in fact:
  • create on the net-share folder a directory with name pattern as PC Name - date - time (e.g: PC-123_2023-07-30_16-12-13)
  • check what was there on last execution
  • create sym links for files that:
    - are existing in the old Backup
    - are existing in the live machine
    - have not been altered on the live machine since last backup
  • copies over all new and changed files form the live machine.


After a certain amount of time (e.g.: once a year) or manually triggered, the "synchronize" should create a full copy without the sym-links.

There should be a second user for the NAS net-share, that has only read access, that can brows the folders to retrieve the files needed.

What is not wanted:
  • solution based on Image creation
  • solution based on non-common file formats (for archives, etc)
  • solution based on closed source application


Is there any set-up that can does what is described here?
