Use an online backup service to diversify how your Mac's data is kept safeWhat are the best online and offsite backup services for your Mac? Here are the ones that could literally save your bits. All of them!
Time Machine or another local backup tool for macOS should be your first line of defense. You should always have a way to recover if you delete an important file or if your hard drive fails. But backup hard drives can go bad. What's more, if you have a major catastrophe, like a robbery, house fire, or flood, you could lose your backups along with your primaries. To make sure your backup strategy is complete, you need to take it offsite and a simple way of doing that is to take it online. That's right — to the cloud!
