I'm really loving Scale as more of my background is in Linux, although I had the issue I'm about to link to on both platforms!

I made a post last night to stackexchange detailing my situation - but I thought it might be better placed here.

I am just starting out with FreeNAS/TrueNAS in preparation for a set of builds I will doing this month. I'm very excited about the new zfs encryption and the marketed ability to send an encrypted dataset to an offsite TrueNAS without also sending the encryption keys. Unfortunately, I ran into an...

Thanks in advance to anyone who responds!

I solved this myself after RTFM.

Code:

foo@BAR:~# zfs send --verbose -I tank/data@auto-2020-11-24_20-50 tank/data@manual-2020-12-09_11-14 | zfs recv -Fv reservoir/data
total estimated size is 619G
receiving incremental stream of tank/data@auto-2020-12-01_00-00 into reservoir/data@auto-2020-12-01_00-00
