I backed up a folder that had a file (file1) and a subfolder containing another file (file2). Then I deleted everything and restored everything back in place.
After restoring you would expect everything to have the same exact creation/modified/accessed dates (in Windows) they did before being deleted. But instead, the subfolder’s creation date is changed to when it was restored, as is the creation date of the file within the subfolder (file2).
The file in the top folder (file1) retains all of the original timestamps. So at the very least, the behavior is inconsistent depending on whether the file is in a subfolder or not.
It seems like a small issue, but if you use creation timestamps to search or filter for files, you’d lose all of those creation timestamps if you ever had to restore from backup.
