After the initial backup – during which the complete organization data gets backed up for the first time – our application backs up new versions of file/folder only when there are changes, based on the last modified date.
If you have only moved the file/folder to a different location without any changes to the content, then the last modified date will remain the same.
If and only when you make changes to the content in the file/folder, it will be detected, backed up by our application, and saved to its new location in the Drive backup archive.
