Setting Description
Encrypt transfer QTS encrypts the snapshot before replicating it.
• The job must be run by the NAS admin user
• The port used by this job must be the same as
the SSH port on the destination NAS
Compress transfer QTS compresses snapshots when replicating them.
This consumes more CPU and system memory, but
reduces the amount of bandwidth required.
Tip

networks, or if the NAS devices are
connected through a WAN.
Maximum transfer speed Limits how much network bandwidth this job uses
