Rsnyc to a Specific Folder

For simplicity, I want to label a folder in each HDD as Media1, Media2, etc, and in that order in the rack. I'll have sub folders as I require. Movies, Documentaries, TV, etc. Because of the multiple folders (that will become sub folders) I think it will really aid sharing and permissions.

I created a folder, Media1 on the first HDD XXX, but I'm unable to "Move" the sub folders into it. They will only Copy and there's not enough room. So on the BackUp YYY, I created the folder Media1 and used the Rsync command.

rsync -auv /srv/dev-disk-by-uuid-XXX /srv/dev-disk-by-uuid-YYY/Media1/

I got a bunch of folders, Movies, Documentaries, etc, with Media1 being one of them. ...and Media 1 was empty. Obviously I don't understand what I'm doing. If truth be known, I don't understand much of anything.

I want all the folders (Movies, TV, etc) to be on disk YYY, and nested inside the Media 1. Then I'll mirror it back to the original HDD which will avoid the possible loss of data if I make a mistake.

Can someone be so kind to help me with this? Thank you so much.

I was originally going to use mergerfs but then I learned that while it keeps a full episode on one drive, it will stripe the series across various drives, using the drive with the most room. I want to keep all the episodes of a series together in a specifically labelled folder(s) on the HDD.

Mergerfs still won't solve the problem of so many shares, permissions, SMB, etc, for each folder. One root folder for each disk, with recursive attributes checked..... would seem to make it much easier for me, as just a home user.

If I share and give recursive permission to this one main folder, it makes things much simpler. Otherwise every single folder has to be done individually. ...and reversed when it becomes necessary.

That's the problem, I can't create the nesting with my Rsync job. Can you please tell me the syntax?

Yes, I set up the share Media1. I can see it. I set up the rsync job, but TV, Movies, etc don't end up nested in Media1. They end up as folders by themselves, with Media1 empty.

rsync -auv /srv/dev-disk-by-uuid-XXX /srv/dev-disk-by-uuid-YYY/Media1/

Can you please tell me what have I done wrong in the sytax?

I'm aware of the importance of placing slashes correctly. This was not my first Rsync attempt at this (the attempts of which I won't bore you) and consequently I set about learning the correct placement of those slashes. I thought I had them right and reading your link, I still think I have them placed correctly, but clearly they aren't.

My daughter's husband recommended I use the mv (Move)or cp (Copy) command, which I will try in command line.
