From what I can tell (yeah it's pretty unclear), Dropbox Backup is a Backblaze-like plan that keeps a backup copy of your files without counting against storage capacity. I'm not sure if they also have a policy to delete backup files for deleted local files after X days, though. EDIT: FAQ[1] for "what if I accidentally deleted a backed-up file" mentions the same "restorable up to 30 days" line as normal Dropbox, so I'm guessing anything you delete locally is gone from backup as well. 1: https://help.dropbox.com/installs-integrations/desktop/dropbox-backup-faq https://help.dropbox.com/installs-integrations/desktop/dropb...
