Backup Best Practices
1
Keep 3 total copies: your original plus 2 backups on different storage types
2
Store at least 1 backup offsite or in the cloud (encrypted!)
3
Test your backups regularly - a backup you can't restore is useless
4
Automate your backups so you don't forget
5
Use the 3-2-1-1-0 rule: add 1 offline/air-gapped copy and 0 errors in recovery tests
