  • I actually don’t know whether timeshift can just run easily from a live USB, but I don’t see why not.

    But of course that also requires you to have installed and set up timeshift before (which is obviously a good idea)

    It’s quite a different deal when the whole operating system it built around a timeshift-like concept.



  • ZFS doesn’t really support mismatched disks. In OP’s case it would behave as if it was 4x 2TB disks, making 4 TB of raw storage unusable, with 1 disk of parity that would yield 6TB of usable storage. In the future the 2x 2TB disks could be swapped with 4 TB disks, and then ZFS would make use of all the storage, yielding 12 TB of usable storage.

    BTRFS handles mismatched disks just fine, however it’s RAID5 and RAID6 modes are still partially broken. RAID1 works fine, but results in half the storage being used for parity, so this would again yield a total of 6TB usable with the current disks.









  • My home-assistant installation alone is too much for my Raspberry Pi 3. It depends entirely on how much data it’s processing and needing to keep in memory.

    Octoprint needs to respond in a timely manner, so you will want to have the system mostly idle (at least below 60 percent CPU at all times), preferably octoprint should be the only thing running on the system unless it’s rather powerful.

    If I were you, I would install octoprint exclusively on your Raspberry Pi 3, and then buy a Raspberry Pi 4 for the other services.

    I’m running Pi-hole and a wireguard VPN on an old Raspberry Pi 2, which is perfectly fine if you are not expecting gigabit speeds on the VPN.
