Several backup services offer free online backup plans. The only catch with a free plan is that, compared to their premium plans, you're restricted in how much data you're allowed to back up.
Aside from the relatively small amount of storage space you're allowed to use, a free online backup plan is usually identical to the paid plans offered by the same company. This means that, as long as a free plan has enough storage space for your data and meets your other criteria, you can get a complete and permanent backup solution for free!
