Stay proactive and regularly check on your backup devices to check their integrity, ensure that your stored data is current, and to see if new, better methods for backing up your data are available.
Prioritize the data you back up to make sure that you are protecting the materials that are most valuable and irreplaceable.
Include one off site backup away from your computer, either using iCloud or an external hard drive, where you can retrieve your data should something disastrous take place near your computer.
iCloud may not offer enough space to back up all of your data, especially if you have lots of music, videos and photos. In that case, you may want to consider another cloud storage program such as Google Photos or Microsoft OneDrive.
Back up your data to multiple places, including external hard drives and iCloud storage, to ensure that you have a variety of options in case one backup fails.
Save your data on CDs, DVDs or Flash Drives as a supplementary backup.
