So I just upgraded from Truenas Core to Truenas Scale 24.10.1 and had to re-create my rsync setup between 2 truenas servers. I gave the rsync app a quick try and also tried setting up an ssh task between the 2 servers. I was able to get the ssh setup working, which leads me to this question: Is there a reason I should consider using the rsync app instead of ssh? The ssh option seems to be working fine, but I am curious if there are features I am missing.
Thanks for any feedback.
Rsync via “daemon mode” (modules) has less overhead, no encrypted stream. This uses less CPU and can result in slightly faster transfer times, especially for low-power systems. (My TerraMaster, for example, has a dual-core Celeron. Trust me when I say that large/numerous transfers over SSH consume most of the available CPU power.)
For a trusted local network, especially within your own home, unencrypted transfers are not a risk. SMB does not encrypt in-transit by default, either.
