Guard the media right by knowing your data is backed up safely.
Invest in an external hard drive or a network attached storage unit.
Then schedule backups on a regular basis.
So Macs, try using Time Machine which will automatically backup your data.
Also, make sure you have multiple backups, such as in the cloud and on physical media.
Also, remember your phone.
For photos, apps like GooglePhotos or Dropbox have auto upload features to backup images to the cloud.
Keep security software and operating systems up to date.
For Windows PCs, make sure you check for the latest patches by going to Windows Update and then check for update.
Finally, use the new year to change your passwords.
Use the combination of upper and lowercase letters, numbers, and symbols.
