What is cloud storage?

If you have dozens of files (eg: from single documents to videos, even for games) on your computer, you may know the importance of having enough space. This is beyond physical disks, but unlimited cloud storage plans can help you. In a simple word, cloud storage is a great alternative to physical disk.

With cloud storage, your data is stored on a remote server and protected from local and natural disaster, such as, system crash, hardware issue, virus, fire, thieves, and more. Also, the cloud storage is full controlled by service provider, so you don’t need to worry about data security and have time to do more meaningful things. Besides, you can access the files on cloud storage anytime, anywhere.

Cloud storage types: traditional vs cloud sync vs cloud backup

Traditional cloud storage: This type of storage solution is used to keep virtually any type of file safe, and you can consider it as a cloud-based hard drive. Also, its provider allows users to access files from any device via providing desktop or phone apps and APIs.

Cloud sync: This is probably the simplest cloud storage and help users sync individual files when any changes are made, such as, photos, contacts, calendar data etc. And it’s highly suggested to make multiple copies of your important files, because you may delete then by mistake.

Cloud backup: Unlike cloud sync, cloud backup is always automatic and you don’t need to select files manually. And it will backup the entire device and save it to a remote server.

Essential features in the unlimited cloud storage options

Truly unlimited cloud storage space: When you search “best unlimited cloud storage”, “free unlimited cloud storage”, or “unlimited cloud storage”, you just want to get unlimited cloud storage. Please check the details and fine print of your preferred plan, you will get some useful warning messages, including file size limit while uploading, bandwidth limitations, etc.

Faster transfer speed: Almost all cloud storage requires a good internet connection, including local internet speed, provider’s features, and this determines how much time you will spend. A service use solid-state hard drives and up-to-date server will greatly accelerate internet connection speed. Besides, speed-focused feature like block-level transfer is also help, because it only backup the changed parts of files.

Security issue: This is another noteworthy feature for users who want to use unlimited cloud backup rather than physical storage. To prevent unwanted access, cyberattacks, or risk of data loss, you need to see if the provider has advanced security protocols, for example, zero-knowledge encryption, 256-bit AES (TLS/SSL) encryption, end-to-end encryption, two-factor authentication and the ability to remove login information remotely, etc.

Apps and accessibility: Flexible access is the key feature of most cloud storage services. But not all of them provide desktop apps for Mac, Windows, Linux or mobile apps for all iOS and Android. You need to check before using any cloud-based software.
