Replication

If the MSDP storage server is used for replication, the following considerations need to be reviewed:

  • The Data-in-transit (DTE) encryption feature is not integrated with MSDP storage for replication workflows and it is controlled by the OPTDUP_ENCRYPTION flag in pd.conf.

  • The job DTE mode depends on the image DTE mode or the global DTE setting of the source domain.

  • The correct values must be set for the DTE configuration settings and the OPTDUP_ENCRYPTION flag for the source and target domains.

For details on enabling encryption using MSDP, see the NetBackup Deduplication Guide.
