Uploading Veracrypt encrypted partitions/volumes to clouds

Hello everyone.
With the backup of my files in mind, I'm thinking about uploading some volumes to a cloud like Dropbox or Mega, but having no experience uploading such thing, I decided to ask here if it works normally like uploading any other type of file.

Say I want to backup my 100GB volume to Mega, for example, having their sync software already installed here in my computer, I assume I only need to move the volume to the syncing folder and wait until the uploading completes, right? Is it really that simple?
And if I later on mount this volume and put more files into its free space, will the syncing software recognize such new files and "update" the volume with its new contents as expected?

I did some research on this and couldn't find anything regarding the upload of encrypted volumes to cloud services. I apologize if this question was already answered and also for not having done these tests myself before making a new thread, I have a very slow upload speed.

Thank's in advance.

In VeraCrypt main window, go to Settings > Preferences, and look for "Preserve modification timestamp of file containers" and uncheck the box. By unchecking this option, you are telling VeraCrypt to allow the timestamp of the file container to be updated to allow the software sync to recognize that the file has been updated.

Also read the following and understand the risks.

A single 100GB container will mean that every tiny change of the container will result in a 100GB upload. This is true (as of now) for all providers except Dropbox. They are the only ones that offer the so called block level verification/uploads.
