My first job was in a Big Iron shop in the late 80's, where I was in charge of backups. We kept Three sets of backups, on two different media, one on hand, one in a different location in the main building, in a water and fireproof safe, and one offsite. We had a major failure one day, and had to do a restore.

Both inhouse copies failed to restore. Thankfully the offsite copy worked. We were in panic. That taught me to keep all my important data on three sets. As the old saying goes: Data loss is not an if question, but a when question. Also, remember that "the cloud" simply means someone else's remote servers over which you have no control.
