CAN I USE THIS FOR BACKUP?

A lot of people try to use cloud drives for backup, and that’s something you can certainly do — if you do it right. At their base level, these are syncing tools, not backup tools. If you accidentally delete or modify something on your PC, it will also delete or modify it on the synced drive. That’s not ideal for backup.

But if you combine it with a backup application that takes care of versioning, it can work. Some vendors like Google actually provide these tools, but you can also use a third-party backup app and set your cloud drive folder as the backup target.
