Backups are useful only when all of the following are true: * Done regularly in an automated fashion (if it’s manual, you will forget); use what comes with your OS or buy a good paid backup application * Keeps older versions with a particular scheme (if you only sync, then your backups will pick up bit rot, and unintended deletions which are manual or through malware) * Have multiple backups on different media and different locations (external drives break, cloud services lose data, your friend’s house may get burgled); you must have local copies (fast) and online copies (physically remote) I have backups on external drives, a NAS and a cloud backup.
