If you have a reasonable internet connection at home this might be the moment to get your own server. Next to online storage (Nextcloud/Owncloud, Seafile) it can host your mail (postfix/exim w/dovecot + spamassassin + sieve), source repo (gogs/gitea), miscellaneous web things you might want to host, media streaming server (airsonic, ampache, etc), personal VPN (openVPN) and more. This gives you far more flexibility (and storage) than commercial online storage/sync solutions for the price of some work to set it up and the electricity to power the thing.
