What Makes CBackup Stand Out ?

Free Online Backup Service Forever

You may find lots of free online backup solution providers. However, most of them only allow you to use the cloud backup services for 15 or 30 days, and ask for money if you want to continue.

Luckily, CBackup provides a permanent free cloud backup plan without any cost. Back up your precious files and memories to cloud without spending a penny now!

Combine Free and Paid Cloud Storage

CBackup enables you to combine multiple free cloud storage services into a larger, even unlimited cloud backup space without paying money to buy storage for critical data backup. For example, Google Drive provides 15GB free storage, so you can easily get 45GB backup storage by adding 3 free accounts of Google Drive into CBackup. Dropbox and OneDrive are also supported.

Besides, you can use the backup software to merge your paid idle storage into a larger backup space to protect your important data.

Protect Your Data with File Backup and File Sync

Both backup and synchronization are provided to protect your data from loss. Your important data is safe even if you accidentally delete them or your computer crashed.

With CBackup synchronization, you do not have to manually download and upload files between multiple cloud storages or accounts. It can be easier and faster for you to sync data between Dropbox and Google Drive or other clouds. You may find lots of free online backup solution providers. However, most of them only allow you to use the cloud backup services for 15 or 30 days, and ask for money if you want to continue.
