Hi @MTZ , #selfhosting could be a move in the right direction for you. I started managing my own servers over 10 years ago, locally, from my home, later VPS and finally again from my home. Eventually I moved toward @yunohost - it simplifies a lot of things! I documented some my experiences at https://wasi.ovh
Start small: setup file/photo sync (@nextcloud), calendars and contacts and gradually start adding data from old backups once you feel comfortable.
Have fun and good luck :)
