On this Valentine's Day episode of TrueNAS Tech Talk, Kris and Chris discuss the recently-released TrueNAS 25.04 Fangtooth BETA (available now!), explain some of the differences between the various methods of backup in TrueNAS, from file to S3 to replication (RAID is not a backup!) and tackle a couple of viewer questions, from the base distro choice to a breakdown of Special VDEVs, from sizing to redundancy to small file allocations.
