Sync Cloud Storage

The simplest definition of a cloud-to-cloud sync is an exact copy.  To be more specific, syncing cloud storage is to sync data between different cloud storage so that any changes or updates to data and new uploads are all available across different clouds. Usually, we have no official tool to sync two or more clouds of different brands directly. But with the help of some excellent multiple cloud storage managers, you will be able to sync between cloud services with most ease.

Why Sync Cloud Drives or Storages?

You can find so many advantages listed below if you try to sync between cloud storage services.

Save Local Disk Space

Today, our work and life can’t live without computers, laptops, and pads. We create many documents, download videos and movies, take photos and store all of them on the hard disk. As time flies, the storage of our hard drives becomes crowded and crowded. Luckily, with the development of computer technology, cloud drive comes! It is the cloud computing era now. Although our local disks are full, we may save our data to the cloud without stress.

Access Cloud Drive Everywhere

The greatest advantage of a cloud drive is that we can visit our data everywhere through the Internet. Not only computers can connect to Internet, but also mobile devices, such as iPhone, Android phones, pads, handheld game players, and so on. With these devices, you can easily access cloud files without any barriers.

Put Double Security to Cloud File

When you can’t enter one cloud drive (forget a password or the service is during maintenance), you can get still access those data by entering another cloud drive that you have synced before.

Use Same File on Different Cloud Easily

If you prefer to use Google Drive (with a Google account, you can be free to log in to all Google services), while your company requires you to use OneDrive, which has a public account for you, you can sync Google Drive with OneDrive to conveniently access same files from different clouds.
