By default, Carbonite Server Backup manages your encryption key for you using Advanced Encryption Standard (AES) 128-bit encryption. If you choose to manage your private encryption key, your backups will be encrypted using AES 256-bit encryption.
By default, Carbonite Server Backup manages your encryption key for you using Advanced Encryption Standard (AES) 128-bit encryption. In the event of a disaster recovery, you only need to remember your account username and password to access the files in your backup. If you choose to manage your private encryption key, your backups will be encrypted using AES 256-bit encryption.
 
Note: With Private Key Encryption, you are responsible for safe and secure storage of your encryption keys. Carbonite does not store your private encryption keys or passphrase anywhere. Replacement keys can be created if you remember your chosen passphrase. If you lose your private encryption key and forget your passphrase, neither you nor Carbonite will be able to decrypt your encrypted backup data.
 
If you decide to manage your own encryption key, we highly recommend that you store at least two separate copies of the key on removable media and store at least one copy of the key in a separate physical location, such as a safe deposit box. The encryption key (or passphrase) is required in order to restore your backed up data.
While managing your key, you will be able to create and save a backup set encrypted with the private encryption key.

To manage your private encryption key, open the Carbonite Server Backup user interface and click the Edit within the Advanced backup settings section in the Backup tab.

Within this window, you will be required to provide information for these fields:
  • Key Name - Enter the name of the private encryption key you are creating.
  • Passphrase - The passphrase will be used to generate the encryption key. It must be at least four characters in length.
  • Confirm Passphrase - This is to ensure that the passphrase you have entered above is the one you would like associated with your encryption key.
  • Save at - Displays the location where CSB will save this newly created key. By default, it will be saved in CSB's encryption folder located in C:\ProgramData\Carbonite\Carbonite Server Backup(x64)\zcb\encryption\. You have the option of choosing an alternate location.
After entering all the required information, click OK to proceed.
