With outages happening with multiple cloud services, including Google's Gmail and Microsoft Office 365, users should use cloud backup to help save their information in case of a prolonged outage. Windows IT Pro said a worst case scenario can lead to a system failure and a large backlog of email or missing information.

"No one controls the internet, so offline access to information is important because it allows users to continue working with locally cached data when problems occur," Tony Redmond of Windows IT Pro writes. "Microsoft is ahead of Google in terms of clients that are able to continue functioning when the network fails."

Redmond said no one can predict outages, but there can be questions about what kind of backup systems providers use, when changes will be made and how to measure what kind of cloud backup a business may need.

PCMag's website said online backup services can help businesses that are trying to prevent loss of information in case of a disaster. The website said online data backup securely store files at an off-site or cloud server, which helps in case of theft or disaster.
