Restore

In the restore workflow, there can be two DTE scenarios:

  • When the image DTE mode is Off

  • When the image DTE mode is On

In either of the scenarios, there can be one or more media servers involved (if multiple images are selected) while restoring data on a client for single NetBackup job.

Image DTE mode is Off

Table: Media server DTE mode is On (default)

Image DTE mode is On

If the image DTE mode is On, the default behavior is to restore with data-in-transit encryption for 9.1 and later hosts and to fail the job if any DTE unsupported host involves in the workflow . However, you can still restore by ignoring the image DTE mode.

Use the DTE_IGNORE_IMAGE_MODE configuration option that is to be set on the primary server. Possible values: NEVER (default) | ALWAYS | WHERE_UNSUPPORTED
