The correct answer is D. all of the mentioned.
An unmanaged storage utility is a software program that allows users to store data on a remote server without having to manage the server themselves. This type of utility is often used for backups, as it can automatically back up data to the server on a regular schedule.
Xdrive, omnidrive, and freedrive are all examples of unmanaged storage utilities. They all allow users to store data on a remote server and back up data automatically.
Xdrive is a cloud-based storage service that offers a variety of features, including file sharing, synchronization, and backup. It is a popular choice for businesses and individuals who need to store and access files from anywhere.
Omnidrive is another cloud-based storage service that offers similar features to Xdrive. It is a good option for businesses and individuals who need to store large amounts of data.
Freedrive is a free cloud-based storage service that offers limited storage space. It is a good option for individuals who need to store a small amount of data.
All three of these services are examples of unmanaged storage utilities that can be used to do automated backups.
