Why I Don’t Rely on Time Machine
This is a good time to remind people about proper backups: the 3-2-1 rule.<p>3 backups.
2 backups (or more) should be on different mediums.
1 (at least) should be offsite (ie. home copy at work or in the cloud)<p>You need three backups.  If we assume that every copy has a chance small but real chance of failure, the chance of all failing at once becomes exponentially less with each copy.<p>You need at least two different systems (media) for backup to reduce the possibly that one of them appears to be backing things up, but is in fact corrupted.  So, two of some system, like Time Machine, Carbonite, Backblaze, Arq, rsync, etc.  Ideally, you need to be able to verify your backups.  Backups that stores things as files means you can periodically try pulling down some files to make sure they&#x27;re good.  Cloud backups should be in the mix, but consider them last resort for restoration as they are usually pretty difficult to verify everything is good.<p>You need one offsite to prevent your house burns down and takes your machines and local backups.  You can do this with physical media rotation (ie. have two machine backups swapping places with home and work) or have a backup to the cloud.
