I have been syncing my Windows library files (Documents, Downloads, Pictures, Videos) using Dropbox for years. But I keep getting messages about trying Dropbox Backup.
What is the difference? Will files in Backup sync and be available on multiple devices? Does Backup support versioning? In which case I don't need Sync.
Contrariwise, will files I'm syncing be backed up, in the sense that I can use them to restore my files in the event of a crashed computer? I know Sync supports versioning; I've used it. In which case I don't need Backup.
Which one, Sync or Backup, protects me best against malware or ransomware?
Or for extra protection, can I, and should I, use both Backup and Sync for the same folders?
