Interested in your thoughts.
Is snapshot and replication to a different TrueNAS system at a different site officially a ‘true’ backup?
Please explain why either way.
IMHO
Is part of very good backup strategy, yes… But depending on situation not at all, cuz be on different site don’t ensure that you can fast recovery/access data

Replication to a different system yields a full, valid and validated, copy of the data to a different system. I do not see why it would not count as a genuine backup.
Or you have to explain your definition of “backup”.

How do you define “officially a ‘true’ backup”?
Great question as this statement seems to mean different things to different people. Let me re-word it. In your opinion is this a backup that is comparable to something more traditional such as Commvault or Veeam taking a backup of your data and storing it in another location?
Well, it’s a copy of your data, byte for byte, in another location. I consider that to be a backup. But again, it’s really a question of definitions.

It is a backup, but it can still differ from Kopia or other backup systems in that it depends on his retention and schedule if it’s basically “equivalent”, and you might consider encryption. But it certainly should be equivalent. And it may be better in the sense that you have bitrot protection, depending on the compared to backup system (a lot of people seem to use rsync to a non ZFS system).
Where it’s different is you may have several pools or datasets replicated, vs, one backup via some other tool. So sort of multiple backups vs one. Same result though.
A backup strategy as others have mentioned is what you need if you don’t have one. I use the 3-2-1 backup rule and have several forms of backups.
