Merge (maybe split) backups on stackip

Hi i’m new to this, i have multiple stackip account (TransIP | STACK - Jouw online cloud opslag each 1tb free) can i merge them to one ‘big’ backup account?

Any tips?

GitHub - trapexit/mergerfs: a featureful union filesystem might work for this… possibly together with rclone.org

The RAID backend #479 is a feature request for something like this. As usual, it may or may not be done.
Personally I worry about anything that makes Duplicati’s life more complex. It increases risk of problems.
Additionally, big backups means more potential loss if it breaks. Multiple small ones would be safer there.
