■ Optimized duplication jobs failover to other FT paths if they exist. If no other FT
paths are available, they failover to the Ethernet network. If no FT connection
or IP connection exists, optimized duplication jobs fail.
■ If no FT connections exist, NetBackup uses an IP connection for new jobs.
About SAN client backup and restore paths
Figure 1-7 shows the possible backup and restore paths for a NetBackup SAN
client.

The following items describe the paths in Figure 1-7:
■ FT between the client and the 52xx or 53xx appliance. The backups reside on
disk storage on the appliance. You can use FT both for backups to deduplication
storage and backups to AdvancedDisk storage.
■ FT between the client and the 50xx deduplication appliance through the 52xx
or 53xx appliance. The traffic travels through two different SAN zones. The
backups are deduplicated and reside on disk storage on the 50xx deduplication
appliance.
■ FT between the client and a 52xx or 53xx appliance, and then FC between the
appliance and the tape library. The traffic travels through two different SAN
zones. The backups are not deduplicated.
