  • Yes when it comes to RAID, a UPS is a must.

    Linux MDADM is not resiliency against power lose. And will overwrite from master if they are not equal.

    Cow system ZFS, LVM, BTRFS and similar, have separate metadata table to compare against. But even then they can be affected by write hole in the event of a powerloss.

    If you are thinking it for “backup” for redundancy in case of disc error, a solution can be to use something like borg backup, and a source disk as a BTRFS file system so you can be notified if there is checksum errors.

    A cheap UPS is 60€, it will work good enough.








  • You write that you need help. From the questions it sound like you need experience. You may not like my answer.

    BTRFS and ZFS are very similar, try them out figuring out.

    Try LXC if it doesn’t work for you, use standard VM.

    There is nothing wrong with have all in one machine, one VM per service or a hybrid.

    There is nothing wrong with using a WLAN as long as you accept the consequences of that.

    I think you should try it out and get some experience, what is the worse that can happen? You learn something and try something different.
