Frequently asked questions
Can I try the service before purchasing a plan?
Yes. A 30-day free trial is available.
How is my device backed up?
All files on your PC will be backed up to C2 Backup servers, including the operating system, installed applications, documents, and media files. If disaster strikes, you can choose between restoring the entire system or downloading specific files or folders.
How do I manage user accounts?
Our optional cloud directory service, C2 Identity, can create and administer user accounts. C2 Identity provides a self-service portal where users can manage passwords and other application services.
How long does it take to back up data?
Since backup time depends on available bandwidth, network traffic status, and the number and size of files being backed up, we are not able to precisely predict how long your backup will take to complete. Please also note that a full backup will be required the first time, while incremental backups will be performed afterwards. Indicatively, backing up 500 GB of data for the first time may take up to 11 hours at an upload speed of 100 Mbps.
How many devices and Microsoft 365 tenants can I protect with a C2 Backup subscription?
As many as you need. However, if the number of concurrent backup tasks exceeds 40, new tasks will be queued until at least one ongoing tasks is completed. As an example, 3 devices and 4 Exchange user accounts count as 7 tasks.
