Infinite Scale: How to copy files to decomposedfs via CLI?

Hi!

i’d like to copy my personal photo, video and music files from my backup hdd to infinite scale.

My intent is to perform something like this:

sudo cp -r /media/backuphdd/ /var/lib/ocis/storage/users/spaces/0e/
:boom: does of course not work because of the decomposedfs structure

Any idea how I can copy files to decomposedfs via cli?

Alternatives I’ve already considered:

I discarded both alternatives as they feel like short-term workarounds to me. I guess a FUSE overlay as described here (Storage drivers | ownCloud) would be the proper solution for my problem, but this does not exist.

Thanks for your help!
