Sync Is Not Backup — Know the Difference Before It's Too Late

If you delete a file on your laptop and it syncs to the cloud, the file is gone everywhere. Sync means your devices mirror each other — including mistakes. A true backup is a separate, independent copy that does not get overwritten when you make changes to the original.

Many people discover this distinction the hard way, after accidentally deleting or corrupting a file and realizing their cloud service faithfully replicated the damage. Use a real backup solution — one with versioning and offline copies — alongside your sync service. They serve different purposes entirely.
