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.

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: 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 (suppo[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.

A: Cloud-to-cloud backup tasks can be created on both the CBakup web app and CBackup desktop app. In addition, we can also create backup tasks from a PC’s local disk to a cloud drive on CBackup desktop app. For this type of task, we can only view it on the CBakup web app and cannot edit it. 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.
