I would very much like to develop my own sovereign #cloud solution—one that is less about synchronizing or syncing files between devices but more about acting as a long term archive. As the storage backend, I would use #IPFS, and with IPFS Cluster it would be relatively easy to archive this data in a geo-redundant way and make it available long-term.
Unfortunately my developing skill are not the best. So maybe if you're interested for a potential collaboration feel free to contact me.
