Do you need a backup of individual files when they are changed under Windows 10 (hooking the save function)?

Question

Backup

Required: A program that intercepts access before overwriting files in a previously defined folder and first saves a copy of the old file before granting permission to overwrite.
What is it for: incorrect changes are periodically made to files (in most DOC, XLS, DWG) and instead of saving under a new name, they are saved under the old one.
why the win10 built-in backup is not suitable: the built-in backup first makes a snapshot of the entire folder - about 20gb (the ssd disk on the laptop does not allow you to allocate that much, it is also not possible to change the ssd), the file can be changed 1 year after lying down and saved - in such cases win10 overwrites the previous version when the size of the impression is limited.

Answer 1

In any case, this is just to write it yourself.
Unless of course you need a backup.
In the event that a copy of the file on the same disk is enough for you, then it is easier to use shadow copying.
In the case of a backup, you can sketch a script that will -
1) make a shadow copy of the data disk in the morning
2) in the evening all changed files will be pulled out of the shadow copy.
3) and then whatever you like - compress, arrange deduplication or increment, send to storage.

Answer 2

File History in Windows 10 .

file can be changed after 1 year.

And for this you need to make backup copies of files.

Answer 3

Can't think of anything with a git, can it?
