Which form of backup is considered a valid daily method for protecting data?

Cloud backup is recognized as a valid daily method for protecting data due to its ability to securely store data off-site, which mitigates risks associated with local hardware failure, disasters, or security breaches. This approach often includes automated scheduling, which means backups can occur frequently without requiring manual intervention, ensuring that data is consistently updated and protected.

Additionally, cloud backup solutions typically offer redundancy and versioning, allowing users to recover previous versions of files if needed. This flexibility and security make cloud backup a preferred choice for many businesses and individuals looking to safeguard their data on a daily basis.

In comparison, while RAID configurations can protect against hard drive failures, they are not a true backup solution as they do not safeguard against data corruption, accidental deletion, or catastrophic events like fire or theft. Sneakernet involves physically transferring data using portable storage devices, which is not practical for daily operations due to the likelihood of human error and the time involved. Flash drive backup offers portability but lacks the automation, security, and redundancy that cloud backup provides, making it less viable for consistent daily data protection.
