Cloud Backup and Restore

Note: Cloud backup requires a backup license from CTERA.
The CTERA Edge Filer provides cloud backup for the local files to the cloud:

• Simplicity
  Cloud backup requires a one-time configuration. Once configured, cloud backup runs automatically according to the desired schedule, without any need for user intervention.
• Security
  In cloud backup, the data is automatically encrypted and fingerprinted. For even stronger security, you can configure a secret passphrase for accessing the backed up data.
• Versioning
  Cloud backup preserves multiple versions of the data, enabling you to restore the version of your choice.
• Restore Options
  Cloud backup offers multiple restore options:
  • Restore some or all files and folders to a previous version from within the CTERA Edge Filer user interface.
  • Restore individual files or folders.
  • Download files from the CTERA Portal account.

If CLOUD BACKUP was not selected when setting up the CTERA Edge Filer, you have to enable cloud backup in the CONFIGURATION tab, by selecting Cloud Backup > Control Panel in the navigation pane and then clicking Configure it now.
Cloud drive folders are synced with the CTERA Portal and these folders are backed up from the CTERA Portal and not from the CTERA Edge Filer.

The first time cloud backup runs, the CTERA Edge Filer performs a full cloud backup for the selected local folders. Depending on the size of the dataset, this might take a long time. Subsequent backups are performed incrementally and take less time than the initial backup since only data that has actually changed is uploaded.

CTERA Edge Filer backup uses data compression and data deduplication techniques to ensure that the backup happens as quickly and efficiently as possible.

In addition to backing up the files, when cloud backup runs the configuration of the CTERA Edge Filer is automatically backed up to the CTERA Portal, from where it can be easily downloaded and used to restore the configuration settings, as needed.

Backed up files are kept according to the retention policy defined on the portal. For details refer to the CTERA Portal Team Administrator.

Data Security

In addition to using AES encrypted TLS (Transport Level Security) connections all of the data is encrypted using 256-bit AES encryption to ensure that the data is protected against eavesdroppers.

For even stronger security, you can use a secret passphrase. If you use a secret passphrase, the data will not be readable by anyone or any entity without knowledge of the secret passphrase.
