Keep in mind a synchronized file vs a backup file are different things. Although they are similar to some, it's actually closer to a square vs rectangle argument. Most average people only need to sync files, most don't need to do a true "backup".

Sync means that you can go from one device to another no prob and keep going. But if you delete, it deletes it across devices. (ie: Drop box, One drive etc.)

Backup on the other hand once done is a frozen snap shot in time. Most people don't need true backup, just syncing. (ie: Copy/Paste into external drive until you over write the drive). Sometimes you want multiple backups to find a file in a certain stage in a previous time period. Truly backing something up means creating multiple copies of files.


Google drive is a weird in between one. It syncs, but also can create a "backup" of deleted items until you do the true delete of the "deleted files". I haven't had much experience with online backups because I prefer doing local backups like other users.
