Google Drive

The free 15 GB is shared with Gmail and Google Photos, so a busy inbox quietly eats your file space. Paid tiers step up through 100 GB and 2 TB. The Drive desktop app for Windows and Mac lets each folder either stream, using almost no disk space, or mirror a full local copy, a genuinely useful choice on a small laptop drive. Recovery is the weak point. An older version of an ordinary file can be deleted after 30 days or once 100 newer versions exist, unless you mark it to keep forever. Google offers no official Linux client. Pick it when your household already lives in Gmail, Docs and Android, and keep a separate backup of anything you cannot lose.
