We recommend the  3-2-1  backup strategy; at least three or four total verifiable copies of your data, two can be local but on different mediums, and two copies off-site. Back-up monitoring and verification is recommended but a disaster recovery must be in place, because you can still get infected, and data recovery is not guaranteed. Data loss is very real.
