Do I understand snapshots and replication correctly?

I have 2 truenas systems: primary and backup. The primary one takes snapshots, and the backup pulls the snapshots from the primary. Once snapshots are replicated, they are considered backups. If I ever want to rebuild the main, I create a snapshot and replicate it back.

No need to create a snapshot. The entire snapshot history is already there. Just replicate the most recent one back.

Once replicated, do the files have a lifetime like snapshots?

You replicate snapshots of datasets, not individual files. The entire snapshots have the lifetime you define in the replication task. They are read-only at the destination. For restore, manually replicate back.
