Since 1980, I have learned to keep multiple backups, using multiple independent software, stored in multiple locations, on multiple types of media, overseen by multiple people.
An overview of my personal backup system for my primary system a MacBook Pro:
* Boot able mirror to remote hard drive via Carbon Copy Cloner * Data backup using Arq to home file server with RAID, and Google Cloud (previously to Amazon and Microsoft) * Data backup using Backblaze * Data sync via Resilio to home server * Code stored in Git * Some stuff in DropBox primarily sync with iOS apps * FastMail IMAP email synced to a local backup store * I just stopped use of CrashPlan after 9 years
I have other backups going for the home file server.
And of course, my servers for work have a whole other multilayered backup system.
