Let's say FreeNAS A recursively replicates to FreeNAS B with "Delete Stale Snapshots on Remote System" option on, with a retention of 4 weeks. On FreeNAS B I setup a snapshot task for the same dataset with an 8 week retention period. Will FreeNAS B keep the snapshots for 8 weeks?
I'm asking this for my backup strategy. Let's say FreeNAS A is compromised. An attacker can delete everything on a dataset and send the empty snapshots to FreeNAS B. I assume with the question above I'd be safe from such scenario.
