How to properly backup your data:
Experts recommend the 3-2-1 rule for backup: 3 copies of your data, 2 local (on different devices) and 1 off-site.
What to do:
- Keep the original data on your computer
- Backup on an external hard drive
- Backup up on a cloud service
A good backup system requires redundancy, with multiple copies of your important data so the data isn’t lost forever if disaster strikes.
