Snapshot & Restore clarification

[shubham9799 (Shubham Agrawal)]

Files change during snapshot and restore process

I took second snapshot after adding some files and try to find the difference. I found that some files also got removed and some got modified. But if I am adding documents, why some files get removed from the backup? I am asking this because I want to copy the new files to a different location. If some files are getting modified or deleted, then I have no option left and copy the whole repository folder which will be very time consuming.

Here is the new thread as asked.
