Enabling Encryption

To enable encryption for the DR Series system, complete the following steps:
  1. Select Storage > Encryption . The Encryption page is displayed, which shows the current status of encryption of the DR Series system.
  2. Click Encryption Settings. The Encryption Settings dialog box opens.
  3. Next to Encryption , click ON.
  4. Next to Mode, select the mode of key lifecycle management from one of the following options:
    • Static — A global, fixed key is used to encrypt all data.
    • Internal — Content encryption keys are generated and rotated on a specified period of days.
  5. If you selected Internal as the mode of key management, next to Key Rotation Interval in Days, enter the number of days for key rotation when a new key is to be generated. In internal mode there is a maximum limit of 1023 keys. The default key rotation period is set to 30 days by default when the passphrase is set and/or encryption is turned on. You can later change the key rotation period from 7 days to 70 years for internal mode.
  6. Click the Submit Encryption Settings button.
After encryption is enabled, all of the data that is backed up is encrypted and is kept encrypted until it is expired and cleaned by the system cleaner. Note that encryption is an irreversible process.
