In case of Google Drive the file is accessed in a team of ID and file name. Please refer to these links: 1 , 2
As far as we know it is possible to rewrite the file on Google Drive without changing its ID. Here is an example.
If you just modify the file with the same Id and name, Skyvia will handle this.
If you overwrite the file with the same Id, but change its name, Skyvia will not handle this - Import task stores name and Id of the file added to the task.
If you delete the file and create new one with the same name, Skyvia will not handle this, too.
Make sure that file has the same ID and is not overwritten.
