All computer users, from home users to professional information security officers, should back
up the critical data they have on their desktops, laptops, servers, and even mobile devices to
protect it from loss or corruption. Saving just one backup file may not be enough to safeguard
your information. To increase your chances of recovering lost or corrupted data, follow the 3-2-1 rule:
3 – Keep 3 copies of any important file: 1 primary and 2 backups.
2 – Keep the files on 2 different media types to protect against different types of hazards.
1 – Store 1 copy offsite (e.g., outside your home or business facility).
What to use: hard disk, usb thumb drive, cd, dvd, floppy, solid state drive, the cloud??? The the answer depends on your particular situation and needs. If you need assistance, Computer Guy Consulting can help you or your business figure it out. Don’t wait for disaster to strike. Backing up is way easier than emergency data recovery!
