A：CBackup is an online cloud backup software. The web app supports backing up your cloud data to other clouds, which currently supports Dropbox, Google Drive, OneDrive, FTP/SFTP. And, the desktop app can back up both your local data and cloud data to CBackup Cloud. More clouds and features will be supported in the near future.
No doubt, CBackup is safe. It uses three methods to ensure the security of your account and data.
(1) CBackup adopts 256-bit encrypted transmission technology for data transfer.
(2) CBackup's authorization system is based on OAuth, which is a standard authorization framework that enables third-party applications to establish connections to cloud services without requiring a username and password;
(3) Your data and files will not be stored on the CBackup server. They will remain in the original cloud drive. Only with your own permission, can CBackup access your cloud drive account. For more details, please refer to the CBackup Security Technology.
A: Both CBackup web app and desktop app are FREE of charge to back up your data to single or combined clouds.
Free account offers 10 GB CBackup Cloud space without any trial period. Meanwhile, you have total data traffic of 500 GB per month to backup or sync from one cloud to another, as well as backup or sync from local computer to cloud, including Google Drive, Dropbox and OneDrive, etc.

A: There's no trial limit of CBackup Cloud. Everyone can use CBackup to back up data to clouds for FREE. With a CBackup free account, you can have 10 GB CBackup Cloud storage.
As long as your backup data is under 10 GB, it will be free of charge. But do remember to log in now and then, for if you didn't log in in 180 days, your account will be deemed as inactive, and your backup data will be deleted automatically.
After a Basic or Premium account expires, your backup data will be stored for a grace period of 90 days. During the grace period, you should clear the backup data to be under 10 GB or renew the subscription. After 90 days, your data stored in CBackup Cloud will be deleted.

A: CBackup is currently suitable for cloud-to-cloud or PC-to-cloud file backup and restore. We will support mobile device files to cloud backup and restore in future program upgrade versions. Please keep an eye on the upgrade of our products.
A: The storage space of either CBackup web app or desktop app is based on the storage space of the public cloud drives you have bound. The more free cloud drives you bind, the more storage space you can use.

A: Please check your spam folder and try sending the verification code again. If you still do not receive the email, please feel free to contact us.
A: CBackup will determine whether you need to delete the backup data according to your selection. When deleting the cloud drive, CBackup will remind you whether to delete the backup data. If you do not delete the backup data, binding the cloud drive to CBackup again will not affect backing up or restoring files from the original task.
A: Don't worry, CBackup will not delete the original data in your cloud drive. In fact, deleting a cloud from CBackup is only to cut off the connection between CBackup and the cloud server.
CBackup web app supports offline backup and restore files. For cloud-to-cloud backup tasks, once the task has started or you set schedule tasks, you can close the web page and even your computer. For CBackup desktop app, you need to keep it running to perform backup.
The same speed scheme applies to both CBackup web app and desktop app.
The backup speed of CBackup Free account is set as normal, and Basic account gets a faster backup speed, and Premium account can enjoy the fastest backup speed.

A: Some files may be judged as malicious by OneDrive. CBackup cannot read these files and cause failure. Try downloading these files from the official OneDrive website. If they can be downloaded, they are not malicious files. In addition, OneDrive does not support files with a "." in the first character of the file name. Check if the file name contains special characters. If the file name contains special characters, change them and try again. If that's not your case, please contact us with task details or progress details.
A: For some technical reasons, CBackup currently does not support backing up Google Documents. We will resolve this issue in future versions.
A: When you log in CBackup account on website, it can’t delete the backup task created via desktop app. And, the desktop app can’t delete the backup tasks created on website. When you log in CBackup desktop app on B computer, it can’t delete the backup task created via desktop app on A computer. You need to log in CBackup desktop on the original computer that created the backup task, then you can delete the task.
A: When you restore backup to another computer, it will first need to verify data integrity. When the sources in the task are too many, the verification time is long. And, the verification process can’t be interrupted, even though you click “Cancel Restore”. It will wait until the verification ends.
A: Please check the error reason under Details of the task, then perform operations according to the error information. Or, you can contact our support team ([email protected]) to check the error further.
A: Backup feature will save your files to the destination based on the specific backup rules of CBackup. It will generate the backup versions, so you can restore them to the previous status. Backup files under every backup version can’t be accessed directly. You need to perform a restore, then you can use these files. Sync feature will directly copy files from the source to target cloud without history versions. You can directly access and use these files in the destination.
A: In order to improve the efficiency of the backup and the space utilization of the Storage Pool, CBackup will split larger files into 32MB file blocks to backup. And, you cannot directly open backup files in the destination. But, please be assured that this will not affect the integrity of the file. You can use these files when you restore them. If you want to directly copy files to the destination cloud without splitting, you can try to use sync features.
A: Please check if the destination clouds that saving backups are disconnected. Please try to re-connect it to CBackup, then try again. Please check if you move the backup versions to another location. If yes, please put them to original path in the target clouds. Please check if you have deleted the backup versions.

For other cloud-to-cloud backup tasks, we can edit them on both CBackup web app and CBackup desktop app.
A: Perhaps the source cloud drive or the destination cloud drive in the backup task contains FTP. Since CBackup desktop app does not currently support FTP, so backup tasks that include FTP cannot be displayed in CBackup desktop app. Similarly, for cloud drives that are supported by CBackup web app but not supported by CBackup desktop app, the backup tasks that contain these cloud drives created on CBackup web app cannot be displayed in CBackup desktop app.
