One of the best ways to approach backup is to use the 3-2-1 data backup strategy. That means keeping three copies of your data, on two different media, and keeping at least one copy of your data off-site.
Start by taking a few minutes to think about your data and current backup needs. Also, think about how often you want to download data—you might want to test your backup process monthly. Finally, consider your budget.
