You can arrange them according to any timing you prefer, across multiple directories or all datasets at once. ZFS snapshots act as block-level changes, meaning they’re essentially free if nothing alters the data, using only the differences. When a folder updates, just the change is recorded. These snapshots stay permanently read-only and can only be removed through webUI or SSH—ZFS handles this internally, not specific to Truenas. I maintain several snapshots tailored to different data needs: every hour for short-term retention, every 10 minutes for longer periods, weekly intervals, up to six months. This lets me restore any point in time or rebuild a dataset from an older snapshot to recover files. ZFS also supports replication via snapshots, so you can back them up to a remote server using its built-in process: https://www.google.com/amp/s/klarasystem...plication/. This is why ZFS stands out—it’s a powerful solution, and switching to an LSI HBA would be wise.
I keep nightly backups on a TrueNAS machine at my brother's place using a PTP connection. Once I return from work, I'll set up Avahi.
IPMI isn't essential, but it's helpful when the server stops working and I can't reach the GUI. I intend to relocate the TrueNAS unit to a shelf above the stairwell so my toddler won't turn it off frequently. After implementing IPMI, I believe I'll eventually set up a NAS without it.
You're focusing on enabling communication between devices and network resources. Your brother's comment highlights the importance of security in IoT setups.
I’d capture more frequent snapshots since they’re free, and you probably meant a point-to-point VPN connection. If you both manage homelabs, create a direct VPN tunnel and add both Truenas boxes to it as an extra VLAN, then enable ZFS replication over that link. Haha, that’s a real scenario. I’d assign each device its own VLAN—both wired and wireless. My IoT devices use a separate SSID, which clearly belongs to the IoT VLAN subnet. I’m using three different SSIDs with one UniFi Wi-Fi 6 AP.
