  • Be prepared to change your mind…

    That first install of proxmox / nextcloud / whatever, will be removed and you will setup something else - this is a good thing.

    So, you’ll probably want to get onsite backups sorted early… even if that’s just cloning to an external drive first.

    IMHO don’t consider a NAS as your server - keep them separate. A cheap ebay PC with a couple of drives is fine.

    And, if you’re considering home automation you will want a UPS









  • Not really.

    I keep my data backups (docs, photos, etc) separate from the OS backups.

    So, depending on what you’re using to do the backup, often they can just simulate a restore and just check the backup’s not corrupted. Not really a restore, but at least you know it’s not trash.

    If you’ve backed up your data with a simple copy / sync (ie not a “backup” program), then you can restore your data somewhere else (maybe even jist a part of it) and do a compare.

    But, yeah, if you’re restoring the OS, then it might be ok restoring it in a VM to check it…

    I’m slowly moving towards no OS backups and using Ansible to be able to recreate the system(s) from scratch… of course I need to backup the ansible files too 😉


  • Write things down

    You will break something - and that’s good, it’s the best way to learn - but you’ll want to make a note of what you did / went wrong / how you fixed it.

    Future you will still break things and be grateful that you wrote that thing down

    You’ll buy something and find next year it was the wrong thing (too small, too large, too old, too new), so just get second hand stuff until you know what you need.

    Cabled networks are so much better than wireless, but then you’ll need switches and cables and shelves and stuff… so using today’s wifi is fine, but know where you’re heading.

    You need to store you stuff - that’ll be in a NAS

    You need something to run services on - that’ll be your server

    These might be the same physical metal lump (your 2nd laptop?), they might be separate… play around, break something and work out what feels right for you… and then put your data on there

    … and that’ll break too.

    Just be aware… if sync files between devices. That’s not a backup. (Consider you’ve deleted / corrupted something - it’s now replicated everywhere)

    Having a NAS with 10 drives in a RAID6 array, is not a backup. It’s just really robust against a drive failure, but a deleted file is still a deleted file.

    Take a full copy of your data off your system - then restore it somewhere else.

    Did it work? If so, that’s a backup.
